Abraxan 
A breed of flying horse; the Abraxan is a gigantic, extremely powerful Palomino (FB). The winged horses that pulled the Beauxbatons carriage were Abraxan (cf GF15 ff.); Madame Maxime breeds them (OP20). 
                                             
acromantula  
 
XXXXX 
(CS15, FB) 
A gigantic black spider (legspan may reach up to 15 feet) with a poisonous bite, the acromantula is an anomaly in the
                                             beast / being classification system. While capable of human speech, the acromantula is classified as a beast rather than a
                                             being due to its violent tendencies. It is native to Borneo (FB), where it is believed to have been a wizard-bred species, serving as an example of why the Ban on Experimental Breeding
                                             was put into effect. 
                                             
Note that all spiders, including acromantulas, fear the basilisk above all other living things. 
                                             
An acromantula was stationed at the center of the Triwizard Tournament maze, guarding the Cup (GF31, OP16).

A breed of winged horse, chestnut in color, which lives mainly in Britain (FB) 
                                             
armadillo  
 
(GF27) 
The bile of this creature is used for making potions, including Wit-Sharpening Potion. 
This reference to the armadillo being part of the Wit-Sharpening
                                             Potion may be in homage to a particularly funny advertisement which ran on British television. In the advert, a devastatingly
                                             dim country fellow is offered a Dime candy bar, which is "smooth on the outside, crunchy on the inside." He says that he prefers
                                             to eat armadillos, which are "smooth on the inside, crunchy on the outside!" The presenter says "You're a bit thick, aren't
                                             you?" and the country bumpkin nods happily. Thanks to Wayne Childs for noting this connection. 
                                             
 Ashwinder
 Ashwinder  
 
XXX 
(FB) 
A thin grey serpent with glowing red eyes which comes out of magical fires and lives long enough to lay fiery hot eggs
                                             in some dark and secluded spot. These eggs, while valued as potion ingredients, are very dangerous. If they are not found
                                             and frozen in time, they will set buildings on fire. 
"Ash" comes
                                             from the color of the serpent and also as a reference to it's connection to fire. "Winder" recalls the sideways movement of
                                             some kinds of snakes, such as the rattler. They are sometimes called "sidewinders." 
 
 
                                             
Augurey(Irish Phoenix)  
 
XX 
(FB) 
Thin and mournful-looking bird somewhat resembling a vulture, greenish-black in color, native to Britain and Ireland.
                                             Normally remaining hidden in its nest in brambles and thorns, flying only in heavy rain, the feathers of the Augurey repel
                                             ink. Its distinctive cry was once thought to be a death omen, but it is now known that the Augurey's cry foretells rain. The
                                             augurey eats insects and fairies. 
"augury" - Eng. generally, the art of divination, but specifically, the art
                                             of the augur (one who interprets omens based on the behaviour of birds) 
                                             
 
 
banshee  
 
(PA7, GF21, FB) 
A Dark creature with the appearance of a woman with floor-length black hair and a skeletal, green-tinged face. Its screams
                                             will kill. Seamus Finnigan is particularly afraid of banshees (PA7). The Bandon Banshee was supposedly defeated by Gilderoy Lockhart (CS6) but was actually defeated by a witch with a harelip (CS16). 
                                             
basilisk (the King of Serpents) 
 
 
XXXXX 
(CS16 ff., FB) 
A wizard-bred Dark creature of enormous power, this extremely poisonous giant serpent (up to 50 feet in length) is brilliant green in color with long thin saber-like fangs and bulbous yellow eyes (see more below).
                                             A basilisk can live for at least 900 years given an adequate food supply, and as it can eat most vertebrates (including humans),
                                             this is not difficult to achieve. The male can be distinguished from the female by the scarlet plume on its head, but basilisks
                                             are usually magically rather than normally bred. 
                                             
Basilisk-breeding has been outlawed since medieval times and in the present day falls under the Ban on Experimental Breeding, but this law has rarely been broken even by Dark wizards, since only a Parselmouth can control a basilisk. 
                                             
"Of the many fearsome beasts and monsters that roam our land, there is none more curious or more deadly than the
                                             Basilisk, known also as the King of Serpents. This snake, which may reach gigantic size and live many hundreds of years, is
                                             born from a chicken's egg, hatched beneath a toad. Its methods of killing are most wondrous, for aside from its deadly and
                                             venomous fangs, the Basilisk has a murderous stare, and all who are fixed with the beam of its eye shall suffer instant death.
                                             Spiders flee before the Basilisk, for it is their mortal enemy, and the Basilisk flees only from the crowing of the rooster,
                                             which is fatal to it." (CS16) 
 
 
                                             The phoenix seems immune to the basilisk's deadly gaze (CS16 ff.) The basilisk which lived in the Chamber of Secrets could be controlled only by the true Heir of Slytherin rather than just any Parselmouth (CS/f). When unleashed by the Heir
                                             using Parseltongue, the basilisk searched the castle for its prey, Muggle-born students, which it could identify by smelling
                                             their blood ("I smell blood..." the creature cried as it wandered the pipes). When its eyes were pecked out by Fawkes,
                                             it attacked Harry using its keen sense of smell. Harry killed the basilisk by thrusting a sword through the roof of its mouth.
                                             Harry's arm was pierced by one of the basilisk's fangs, the poison of which nearly killed him. 
                                             
Apart from its specific magical powers and long lifespan, many of the characteristics of the basilisk follow naturally
                                             from its being a serpent (see). Like more mundane serpents, the basilisk sheds its skin at intervals, and its varied diet is typical of the larger
                                             snakes, which tend to pursue larger and larger prey according to their own size and capabilities. It's quite possible that
                                             had Harry been more experienced in Defense Against the Dark Arts, he might have lost his battle against the basilisk in attempting
                                             to use Stunning Spells; although not explicitly stated, the basilisk's skin probably has the same armor characteristics as dragon skin, leaving
                                             its eyes and the inside of its mouth as its only vulnerable points. 
                                             
 "...the basilisk was portrayed as a serpent with a crown or a white spot on its head. Cobras,
                                             which have such marks, may be the origin of the basilisk legend..." (pp. 21-22) (c.f. pp. 95-96)
"...the basilisk was portrayed as a serpent with a crown or a white spot on its head. Cobras,
                                             which have such marks, may be the origin of the basilisk legend..." (pp. 21-22) (c.f. pp. 95-96) 
                                             
"basilisk" Eng. in the legendary sense means this creature, but also
                                             comes from L. "basilicus" royal, so the nickname "King of Serpents" is particularly apt. The detail about males being crested
                                             appears to come from the real-life basilisk, which is a kind of iguana.

Horn of this creature is used as a potion ingredient. The name "bicorn" suggests a creature with two horns. The Bicorn is a mythical demonic creature which eats human flesh.

Billywig  
 
XXX 
(FB) 
A magical insect, native to Australia.It is about a half-inch long and vivid blue in color. A Billywig's sting causes
                                             giddiness and levitation. For this reason, the Billywig's sting is highly sought after by Australian wizards. Dried Billywig
                                             stingers are useful as a potion ingredient.

Blast-Ended Skrewt 
(GF13 ff.) 
Magical creatures bred by Hagrid prior to the autumn of Y14 by crossing manticores with fire-crabs. Blast-Ended Skrewts are some of the most revolting creatures ever seen. 
The name "Blast-Ended Skrewt" may be a reference to the term "blasting off" which is slang in some parts of Britain
                                             for breaking wind.

The Ministry of Magic keeps some albino bloodhounds around to be used against Nogtails (FB). 
                                             
Blood-Sucking Bugbear  
 
When roosters were being killed at Hogwarts (Y12-Y13), Hagrid suspected that the culprit might be a blood-sucking bugbear (CS11). See also bugbear. 
                                             
boarhound - Fang  
 
Hagrid's pet Fang is a black boarhound, "a large dog, specifically the great Dane, used in hunting wild boars". He, like Hagrid, looks a lot
                                             fiercer than he is. Fang accompanies Hagrid into the Forbidden Forest and also went with Harry, Hermione, Neville, and Draco when they served detention in the Forest. Hagrid told them that Fang is a coward, but this may have been more an oblique comment on Draco's behavior
                                             than the strict truth about Fang. When Harry and Ron followed the spiders into the Forest and encountered Aragog, Fang accompanied with them. When Hagrid resisted arrest late in Harry's fifth year, Fang was injured in attempting to protect
                                             Hagrid, but recovered. 
                                             
boggart 
 
 
A shape shifter that prefers to live in dark, confined spaces, taking the form of the thing most feared by the person
                                             it encounters; nobody knows what a boggart looks like in its natural state (although Moody recongnized one using his magical
                                             eye to spot it as it hid in a corner desk at number 12 Grimmauld Place. One wonders what it was that Moody actually saw...).
                                             A boggart appears to feed on the emotion of fear rather than simply deploying this ability as a defense mechanism, hence its
                                             classification as a Dark creature (PA7). Many Muggle children may have encountered boggarts as "the monster under the bed", though this is not stated explicitly
                                             in the text. 
                                             
Lupin taught his third year Defense Against the Dark Arts class to fight this with the Riddikulus spell (PA7), and used a boggart as a substitute for a Dementor in tutoring Harry (PA23), an experience Harry felt the D.A. really needed in order to learn to cast the Patronus Charm under something resembling realistic conditions (OP27). A boggart was one of the obstacles in the Triwizard Tournament maze (GF31), and a boggart was found infesting a writing desk in the drawing room at Grimmauld Place (OP9). 
 " Often they are house spirits, and in those cases the only way to get rid of them is to move...The
                                             more frustrated the family becomes, the more fun the boggart has." (pp. 33-34)
 " Often they are house spirits, and in those cases the only way to get rid of them is to move...The
                                             more frustrated the family becomes, the more fun the boggart has." (pp. 33-34) 
Apparently, Alastor Moody knows what a boggart looks like when it's hiding and away from people, since he used his
                                             magical eye to look up through several flights of stairs and into a writing desk with a boggart inside it. He told Molly Weasley
                                             they what was in that desk was in fact a boggart, so he obviously saw and identified it. On the other hand, it's possible
                                             that when he looked he saw nothing but a blur and therefore knew that--since he couldn't even see it--it had to be a boggart.
                                             
                                             
boomslang  
 
African snake, Dispholidus typus, with extremely nasty venom. The skin, which is mostly green in males and mostly
                                             brown in females, serves the snake well as camouflage, and is used for polyjuice potion. Snape keeps boomslang skin in his private stores (CS, GF). 
"boomslang"
                                             is an English loan-word from Afrikaans, whence it was in turn formed from two Dutch words, "boom" Du. tree + "slang" Du. snake
                                             [NSOED] 
                                             
bowtruckle  
 
XX 
A small (maximum height 8 inches) insect-eating tree-dweller with long sharp fingers
                                             (two on each hand), brown eyes, and a general appearance of a flat-faced little stickman made of bark and twigs, which serves
                                             well as camouflage in its native habitat. 
                                             
Found in western England, southern Germany, and Scandinavia, a bowtruckle serves as tree-guardian for its home tree, which
                                             is usually a tree whose wood is of wand quality. The twiglike fingers of the bowtruckle appear to be primarily an adaptation
                                             like that of a woodpecker's beak, allowing it to more effectively dig out its preferred food of wood lice from its home tree,
                                             but they also serve as an effective weapon against the eyes of an opponent. Although ordinarily peaceful, a bowtruckle will
                                             attack a human if provoked (which includes perceived assaults upon the bowtruckle's tree as well as the bowtruckle itself).
                                             A witch or wizard seeking to take leaves or wood from a bowtruckle-inhabited tree should offer wood lice or fairy eggs to the bowtruckle to placate and distract it (FB, OP13). 
"bow" several English senses, but the obsolete Scottish dialect
                                             sense traces back to much older words meaning "dwelling", while some senses come from the same root as the English word "bough",
                                             meaning the limb of a tree + 
"truckle" Eng. to take a subordinate position 
                                             
bugbear  
 
See Blood-Sucking Bugbear. 
"bugbear" Eng. a type of magical creature (possibly resembling a bear) in legend
                                             that was supposed to eat naughty children; the term (through being used generally as a label for any imaginary being used
                                             to scare children) has come to mean any exaggerated fear based more on imaginary than real danger 
 
 
                                             
Bundimun  
 
XXX 
Greenish fungus with eyes. An infestation of Bundimuns can destroy a house, as their
                                             secretions rot away the foundations. This same secretion, in diluted form, is used in some magical cleaning solutions (FB).

 Centaurs are very mysterious creatures. They avoid Muggles and Wizards alike (FB). Centaurs watch and read the signs in the stars and planets and they do not take sides in the events unfolding around them,
                                             which they have foreseen. They prefer simply to observe (PS15). The Centaurs have chosen to be considered Beasts by the Ministry (FB) and do not take part in governing at all.

This arboreal creature resembles a cross between a monkey and a frog. Its smooth skin
                                             is mottled green. The Clabbert has short horns and a wide grinning mouth. Its long arms and webbed hands and feet allow it
                                             to move gracefully through the trees. On the Clabbert's forehead is a large pustule which flashes red when the Clabbert senses
                                             the approach of danger, including Muggles.

                                             It resembles an ape with large, black eyes and long, silky hair. This hair can be woven into Invisibility Cloaks. The Demiguise is native to the Far East (FB). 
                                             
 Diricawl
 Diricawl  
 
XX 
This plump, flightless bird escapes danger by vanishing in a burst of feathers. Muggles
                                             knew this bird as the "dodo" and believe that it is extinct, being unaware of its ability to vanish at will. Because this
                                             belief (and associated guilt) has spurred more enlightened attitudes toward the animal world among many Muggles, Wizards have

The Doxy is a small fairy-like creature that is covered with black hair. They have
                                             sharp vemonous teeth (FB). Doxies are pests. They can infest houses, taking up residence in the draperies. Removing them requires a good supply of
                                             Doxycide. It's a good idea to have an antidote for Doxy venom on hand as well (OP6).

Dragons, large flying reptiles which breathe fire, are some of the most awe-inspiring
                                             and dangerous of all magical beasts. There are ten varieties of dragons in the world today.

This strange creature looks like just another hunk of dead wood floating in the marshes
                                             in which is lives. The Dugbog has finned paws and sharp teeth with which is attacks small mammals. The Dugbog is particularly
                                             fond of Mandrakes (FB).

XXXX 
The Erkling is a small elf-like creature native to Germany. Its high-pitched laugh
                                             is particularly entrancing to children, which Erklings like to eat. Erkling killings have decreased dramatically over the
                                             last few centuries as the German Ministry of Magic has put in place strict controls over the creatures (FB). 
 "Rowling has transposed a few letters in the name of the Erl King... of German legend. Otherwise,
                                             her description holds true. It is an evil creature in the Black Forest of Germany that tries to snatch children." (p. 26)

This huge African magical beast resembles a rhinoceros. Its horn, which can pierce
                                             almost anything, contains a fluid which explodes, destroying what it has hit. Because male Erumpents frequently blow each

Tiny creatures that look like perfectly

                                             Flitwick decorated his classroom with them (PA10) and the garden was decorated with them for Yule Ball (GF23). Fairies have their own weak form of magic which they use primarily to avoid being eaten by predators. (FB) According to Scamander, fairies are held to have very limited intelligence, and they do not use any form of language that
                                             humans understand (but see languages).

                                             to turn a Boggart into it (PA7). Hagrid once needed a repellent for Flesh-Eating Slugs which were getting into the cabbages, and went shopping for it in

                                             it exudes is used to thicken potions. Hagrid, after losing his nerve with the hippogriff debacle, had his third year students
                                             raise these for a semester, which was completely pointless as they prefer to be left alone and to do nothing (PA6, FB).

Full-blooded giants are about twenty feet tall (GF24). The race of Giants now lives mostly in remote mountain areas, but there was a time when they were a force to be reckoned

See list of non-wizard characters - giants for a list of giant characters. Rubeus Hagrid and Olympe Maxime are both part giant, and are counted as wizard characters

XXX 
The Glumbumble is a magical furry insect. It produces a fluid which causes melancholy.
                                             This fluid is used as an antidote for the hysteria which results from eating Alihotsy leaves. Glumbumbles eat nettles. 
                                             
gnome (garden) 
 
 
XX 
The gnome is a common garden pest resembling a potato with legs. Gnomes live in gnome-holes
                                             underground, where they dig up plant roots and generally cause a mess; their presence is also a dead give-away that a home
                                             belongs to a witch or wizard (Sch1). Every so often, a garden must be "de-gnomed," which involves grasping the gnomes by the ankles, swinging them around a
                                             few times to disorient them, then tossing them out of the garden. Gnomes are rather dim, so when they realize a de-Gnoming
                                             is going on, they all come rushing up out of their holes to see what's going on, making them a lot easier to catch (CS3). Crookshanks loved chasing gnomes around the Weasleys' garden and the gnomes seemed just as much to love being chased (GF5). (also FB)

                                             Graphorn 
XXXX 
A large, grayish-purple creature which lives
                                             in the mountains of Europe. Graphorns have two extremely sharp horns. They are extremely dangerous animals. Graphorn horns
                                             are useful for potions and Graphorn hide is even tougher than dragons' and also repels spells (FB). 
                                             
griffin  
  
 
XXXX 
Strange creature with the front body of an eagle and hindquarters of a lion. Griffins
                                             are used to guard treasure (FB). 
There is a statue of a griffin in a corridor in Hogwarts, near the girls' bathroom where Harry, Ron, and Hermione faced
                                             a Mountain Troll (PS10). 
Godric Gryffindor, the founder of Gryffindor house, may have gotten his name from this beast. The griffin-shaped knocker
                                             on the door of Dumbledore's office may be a pun on Gryffindor's name. 
                                             
Grim (barghest)  
 
The Grim is a ghostly image of a large dog-like beast; seeing one portends death (PA6). 
 
 
                                             
grindylow  
 
XX 
A grindylow is a pale green creature that lives in the weed beds on the bottom of
                                             lakes in Britain. It is also known as a water demon. Grindylows have long, brittle fingers which they use to grip their prey,
                                             sharp little horns, and green teeth. Lupin taught his third year students about them (PA8) 
                                             
Grindylows in the lake near Hogwarts attacked the Triwizard champions during the second task. However, some grindylows appear to have been domesticated by merpeople (GF26). 
                                             
Griphook 
Griphook is a goblin working at Gringotts Wizarding Bank. He escorts Harry and Hagrid down below the surface in the cart, stopping first at Harry's vault, then at vault 713, a high
                                             security vault (PS5). 
                                             
Gytrash 
The Gytrash is a huge, spectral hound which lives in the forest. 
The Gytrash, in the form of a huge dog, horse, or mule, haunts solitary places; it is found in
                                             the folklore of Northern England.

                                             hag  
 
Female human-like magical being, but less adept than a witch at disguising herself from Muggles (PA4, GF19). Hags are what one might refer to as "fairy tale witches." Hags are wild in appearance, and they have been known to eat
                                             children (FB, DP, fw), although at the Leaky Cauldron Harry once saw a hag eating raw liver (PA4). Hags can be quite frightening, apparently, since Quirrell had a "nasty bit of business" with one during his year off for
                                             first-hand experience in fighting the Dark Arts (PS5). Interested parties may also consult Gilderoy Lockhart's book Holidays with Hags (CS4), which probably can be picked up quite cheaply at Flourish and Blotts, Diagon Alley, London, UK these days. 
                                             
hellhound  
 
Muggle name for the sleepless three-headed dog who according to their mythology guards the gates of Hades. The dog's
                                             name was Cerberus, and the only time when he was ever overcome save by brute force was when the great musician Orpheus sang
                                             him to sleep. Hagrid had a huge three-headed dog which he called Fluffy (PS9, PS11, PS16), who now is reported to be living in the Forbidden Forest near Hogwarts (BP). [NOTE: The name "hellhound" does not appear in the books; that is the name given to this type of creature in Muggle mythology.
                                             In the books, the Fluffy is simply refered to as a "giant three-headed dog.] 
                                             
hinkypunk  
 
A little one-legged creature, with the appearance of being made of smoke, the hinkypunk carries a light with which it
                                             lures travelers into bogs (PA9). 
                                             
 hippocampus
 hippocampus 
 
 
XXX 
A Mer-horse, with the head and forequarters of a horse and the hindquarters and tail
                                             of a giant fish (FB). 
hippocampus = (from hippos (horse) + kampos sea-monster) a legendary
                                             Greek half-horse half-fish creature often shown in art drawing the chariot of Poseidon (NSOED). 
                                             
hippogriff 
 
 
XXX 
A flying creature with the head, wings, and forelegs of a giant eagle and the body
                                             (including hind legs and tail) of a horse. The eyes are orange, while individual hippogriff colours vary as those of mundane
                                             horses do, including black, bronze, chestnut, grey, and roan. An adult hippogriff's wingspan is approximately 24 feet (PA6, FB). 
                                             
Hippogriffs are carnivorous and are extremely dangerous until tamed, which should only be attempted by a trained witch
                                             or wizard. That said, hippogriffs can and do live on insects, birds, and small animals such as rats and ferrets (FB, GF27, OP6). 
                                             
A person wishing to approach a hippogriff should maintain eye contact and should bow first; if the animal bows in return,
                                             it can be touched and even ridden. Hippogriff owners are required to keep them under Disillusionment Charms to prevent Muggles
                                             from seeing them (PA6, FB). 
                                             
Hogwarts has access to at least a dozen hippogriffs for Care of Magical Creatures lessons; see Buckbeak for an example (PA6). 
                                             
horklump  
 
X 
This garden pest resembles a pinkish mushroom covered
                                             with bristles, but is actually a carnivorous animal rather than a plant. Horklumps are the favourite food of gnomes (FB). 
                                             
 horned toad
 horned toad  
 
Neville once had to disembowel an entire barrel full of horned toads while in detention with Snape. Afterward, Ron fantasized
                                             about Mad-Eye Moody turning Snape into a horned toad, similar to the 'amazing bouncing ferret' punishment inflicted on Draco
                                             Malfoy (GF14). Horned toads are really lizards, and very fearsome-looking lizards at that. Poor Neville had quite an evening, I think.

human-like creatures 
Creatures that look like normal human beings but which are not (at least
                                             some of the time in the case of werewolves).

The imp is similar to the pixie and the fairy. It is about seven inches tall and is
                                             colored dull brown or black. Imps live in damp or marshy areas. They have a somewhat slapstick sense of humor and they love
                                             to trip people so they fall into a stream. They eat small insects. (FB)

Jarvey  
 
XXX 
Resembling an overgrown ferret, the Jarvey is one
                                             of the few beasts that can actually talk. Its speech, however, consists entirely of rude phrases and insults. Jarveys chase
                                             gnomes (FB). 
"Jarvey" is an old slang term for a cab-driver, dating from the days when cabs were
                                             horse-drawn [NSOED]. 
                                             
Jobberknoll  
 
XX 
A tiny blue speckled bird which makes no sound until the moment of its death, when
                                             it lets out a long scream consisting of all the sounds it has ever heard; their feathers are important ingredients in making
                                             potions that affect memory (FB). 
"Jobbernowl" means a stupid person (NSOED). 
                                             
kappa

A water-dweller resembling a scaly monkey with webbed hands, a kappa will grab and
                                             strangle waders in its pond (PA8). According to Snape, the kappa is commonly found in Mongolia (PA9), but the Care of Magical Creatures textbook states that the kappa is a Japanese creature (FB).

Lockhart once gave Hagrid unsolicited advice on how to get kelpies out of a well
                                             (CS7). The world's biggest and most famous kelpie is the Loch Ness Monster, although it is often mistaken for a sea serpent (FB).

This very intelligent cat-like creature can detect unsavory or suspicious persons
                                             very well and will react badly to them. However, if a kneazle takes a liking to a witch or wizard, it makes an excellent pet.
                                             The kneazle has spotted fur, large ears, and a lion-like tail (FB). Crookshanks is part kneazle (Nr, JKR).

                                             the leprechaun is one of the occasional anomalies of the beast/being classification system. Although they alone of the "little
                                             people" have the ability to speak human language, they are classified as beasts, and have remained in that category as they
                                             have never requested re-classification (although they appear to have made no political statement by this, unlike centaurs
                                             and merpeople. They are able to produce a gold-like substance that vanishes after an hour or two (GF8, GF28). Leprechauns are the Irish National Quidditch Team's mascots (GF8).

This dangerous beast resembles a half-inch thick black cloak which moves along
                                             the ground at night, hunting its prey. It attacks sleeping humans, smothers them, then digests them, all in their bed, leaving
                                             no trace at all. The only defense against a lethifold is a Patronus Charm. Thankfully, this frightening creature is rare,
                                             only found in the tropics (FB).

                                             a venom that is instantly fatal to a victim of its sting. A manticore's skin repels virtually all known charms, so it is extremely
                                             difficult to subdue by magic (FB). In 1296, a manticore seriously wounded someone but was let off because no one dared go near it (PA11). Hagrid bred the Blast-Ended Skrewt from a manticore and a fire-crab; it is unknown how he persuaded the manticore to cooperate
                                             (GF24). 
                                             
Manticores originated in Greece (FB). In the opinion of the Bestiary's assistant editor, they like the acromantula probably originated as a wizard-bred species
                                             specifically created to guard treasures, strongholds, and the like, and serve as an example of why the Ban on Experimental Breeding is so important.

merpeople  
 
XXXX 
Sentient beings who live underwater in villages at the bottom of lakes and seas.
                                             Merpeople speak Mermish, a language which sounds like a horrible screeching noise but which is understandable underwater.
                                             They sometimes use lobalugs as weapons. Merpeople are also known as sirens (Greece), selkies (Scotland), and merrows (Ireland) (FB). The merfolk who live in the lake near Hogwarts are led by Merchieftainess Murcus (GF25). 
                                             
In 1949, some merpeople caught a hippocampus off the coast of Scotland and domesticated it (FB). Some of the merpeople living near Hogwarts keep grindylows as pets (GF25).

 XX 
A strange creature that lives in a burrow. It only comes out at the full moon, when it
                                             dances on its enormous flat feet, sometimes leaving intricate patterns in wheatfields (much to the confusion of Muggles).
                                             The silvery dung of the mooncalf, if collected before the sun comes up, makes an excellent fertilizer (FB).

mummy  
 
The preserved remains of an animal body, possibly human, from which fluids have been removed. Although mummification
                                             can occur through natural processes in very dry conditions, the most common conception of a mummy is that of one deliberately
                                             embalmed as a preparation for burial, for which additional preservative measures have been performed. In ancient Egypt, mummification
                                             was performed on the bodies of humans and of cats, and was considered a necessary step in preparing the deceased for the afterlife.
                                             
                                             
It is unclear whether the type of mummy Parvati Patil fears (which the boggart impersonated during her first Defence Against the Dark Arts lesson with Remus Lupin, PA7), is an actual mummy animated or some Dark Creature resembling a mummy. If the latter is the case, a mummy is a frightening
                                             creature, bandaged, bloody, and sightless, possibly a manifestation of a curse left behind by ancient wizards (PA7). (Of course, if Parvati was exposed to Muggle entertainment as a child, she may just have watched too many horror movies.)

murtlap  
 
XXX 
A seashore-dwelling rodent native to Britain, this ratlike creature has on its back
                                             a growth resembling a sea anemone, which when pickled can be used to promote resistance to curses. The murtlap will attack
                                             anyone who steps on it, although it usually eats crustaceans, not people's feet (FB). 
                                             
Hermione treated Harry's cuts after his detention with Umbridge with murtlap essence (OP15). Harry later recommended the same treatment to Lee Jordan, who in turn suggested it to the Weasley twins when they were
                                             seeking a solution to the problem of the boils caused by their prototype Fever Fudge (OP18, OP26).

XXX 
A black fluffy long-snouted creature which burrows
                                             in dirt as if it were water. Nifflers are strongly attracted to anything shiny, so they can be very useful for finding treasure,
                                             and are often kept by goblins for this purpose (GF28, FB). Native to Britain, nifflers live in lairs up to 20 feet underground
                                             and have litters of 6 - 8 young (FB). 
                                             Fred and George left a couple of nifflers with Lee Jordan when they left school. He levitated them into Umbridge's office
                                             through her window, where they cheerfully trashed the place and attacked her when she walked in (OP31). Although nifflers
                                             are gentle and even affectionate (FB), Umbridge had a habit of wearing rings, and nifflers are prone to attempt to bite off jewelry (GF28).

nogtail  
 
XXX 
Found in rural areas across Europe, Russia, and America; a Dark Creature (classified
                                             as a demon) resembling a piglet, but stunted with narrow black eyes, a thick stubby tail, and long legs. Nogtails curse farms.
                                             A nogtail slips into a pigsty and suckles an ordinary pig; the longer it goes undetected, the longer the curse that falls
                                             upon the farm. The nogtail is very fast and difficult to catch, but if chased off the farm by a pure white dog it will never
                                             return. See the Pest Sub-Division of the Regulation and Control of Magical Creatures for assistance with nogtail problems

XXXXX 
Considered by many to be the most dangerous beast in
                                             existence, the nundu is a gigantic leopard, native to East Africa, whose breath carries disease and death. Whole villages
                                             have been wiped out by the nundu, and no nundu has ever yet been subdued by fewer than a hundred wizards working together
                                             (FB). Compare this with the dragons of the First Task of the Triwizard Tournament in Harry's fourth year, each of which - an
                                             agitated nesting mother - could be stunned by a team of fewer than ten wizards (GF). 
                                             
occamy  
 
XXXX 
A beautiful, carnivorous creature native to India and the Far East, resembling a
                                             winged snake, but plumed, having two legs, and reaching up to fifteen feet in length. As occamy eggshells are formed from
                                             pure soft silver, the occamy's reputation for aggression may be overstated, as most of its interaction with humans probably
                                             has consisted of defense of its eggs (FB).

owl  
 
These birds provide postal service for the Wizarding World. Although Muggles know about them, they are obviously magical
                                             to some extent, since their ability to find the recipient of their letters is extraordinary indeed.

 phoenix 
XXXX 
Swan-sized bird with
                                             gold or red plumage (apart from its golden tail), golden beak, and golden talons. The scarlet plumage glows faintly in darkness,
                                             while the golden tail feathers radiate heat to the touch (CS15). Phoenix tail feathers are suitable for use as wand cores
                                             (PS5), while phoenix tears have healing powers (FB, CS12). According to Scamander (FB), "phoenix song is magical; it is reputed to increase the courage of the pure of heart and to strike fear into the hearts
                                             of the impure". 
                                             
Like the diricrawl, the phoenix is herbivorous; the XXXX rating given to this gentle creature does not indicate ferocity,
                                             but rather the rarity of successful attempts to domesticate it. Another point of similarity with the diricrawl is that the
                                             phoenix can disappear and reappear at will (FB). Phoenixes can carry immensely heavy loads in flight (CS12, CS17). 
                                             
The phoenix's most unusual characteristic is that after its body begins to fail, it dies in a burst of flame, to be reborn
                                             from the ashes. This occurs not only on a phoenix's natural Burning Day, but if the phoenix receives a fatal injury, such
                                             as being hit with a Killing Curse (OP36). 
                                             
Found in Egypt, India, and China, phoenixes nest on mountain peaks (FB). 
                                             
The Moutohora Macaws have a phoenix for a mascot. His name, appropriately enough, is Sparky (QA8).

                                             with a sense of hopelessness until the human collapses, at which point the pogrebin attempts to devour them. The Pogrebin
                                             resembles a grey rock with a small hairy body and it hides by crouching down and pretending to be nothing but a harmless stone

Found in Dorset, England and in southern Ireland, this short (about two feet high when fully grown),
                                             shaggy creature walks on two cloven-hoofed feet and feeds on grass. Its small arms end in four fingers. 
                                             
The porlock lives to guard horses and will be found with a herd or curled in the straw of stables, although
                                             it is so distrustful of humans that it is seldom seen at all (FB).  
                                             
Porlock is a town located along the north coast of Devon, on the edge
                                             of Exmoor National Park. According to the site "What's On Exmoor," "A large group of feral goats lived in this coastal area until about 1910 and their milk, skins and meat were traded at
                                             Porlock Weir..." Perhaps it is this bit of history which suggested the Porlock to Rowling.

                                             are often kept as pets, particularly by wizarding children; Ron Weasley used to own one until Fred used it for Bludger practice.
                                             As scavengers that will eat anything from leftovers to spiders, they are very easy to care for. There was a nest of dead puffskeins
                                             under the sofa of the drawing room of Number 12 Grimmauld Place (OP6).

One of the most dangerous of magical beasts, the quintaped is found only on the Isle of Drear off the
                                             north tip of Scotland. There is a fascinating legend about the origin of quintapeds, which involves a feud between two wizarding
                                             clans and a poorly thought-out magical attack. The reader is urged to read the full account in a reputable source such as
                                             Fantastic Beasts and Where to Find Them by Newt Scamander. The Isle of Drear has been made Unplottable to protect the unwary (FB).

A fat white

                                             in which the performer pulls a rabbit out of a top hat). It is unclear if this is a magical creature or if it had simply been

Red Cap 
 
 
XXX 
Small, goblin-like/dwarflike creatures, Red Caps love bloodshed, and will attempt
                                             to beat to death Muggles lost in dungeons or on battlefields on dark nights. (As red caps can be repelled easily by charms
                                             and hexes, Muggles rather than adult wizarding folk face the most danger from them (PA8, FB).) 
                                             
According to A Field Guide To The Little People (Nancy Arrowsmith

Some of the most bloodthirsty Scottish elves are the Lowland
                                             castle spirits. They are called Red Caps...and by some accounts are said to live only in castles with a history of violence.
                                             Others say they live in all Lowland peel-towers [fortified houses or towers]. It may well be that both accounts are true...The
                                             Red Caps' main occupation is colouring their red caps, which they dye with human blood. They throw boulders on to travellers
                                             from their towers, then catch the blood in their caps. As soon as the blood dries and the colour fades, the Red Caps look
                                             for new victims. They also foretell disasters by making a loud noise like the beating of flax. The only things that discourage
                                             them are crosses, cross-handled swords, and words from the Bible (p. 47).
                                             These Red Caps are described as short, old elves with a sturdy build
                                             and long grey hair. They are about four feet tall and have red eyes.  
                                             Re'em 
 
 
XXXX 
Native to the wilds of North America and the Far East, this extremely rare golden-furred
                                             giant ox's blood gives the drinker immense strength. However, since demand far exceeds supply, re'em blood is found on the
                                             open market only rarely. 
                                             
JKR borrowed the idea of the Re'em from ancient writings, although she created her own description of this mysterious beast.
                                             From The Truth About Unicorns by James Cross Giblin. 
                                             
"In the original version, the Hebrew writers referred seven times to a powerful animal called the re'em. One of
                                             these references appeared in the description of Joseph.... Not knowing what animal the Hebrews had in mind, the authors of
                                             the Septuagint translated re'em as monoceros, the Greek word for unicorn. "There's no reason to believe, however, that the
                                             Hebrews thought of the re'em as one-horned. Some later scholars argued that it was probably the African antelop, the oryx.
                                             They pointed out that the Arabic word for oryx was the similar rim" (page 41). 
                                             The reference to Joseph is from the Biblical book of Deuteronomy: "His Glory is like the firstling of his bullock, and
                                             his horns are like the horns of unicorns...." (Deut. 33:17). (Thanks to Pigwideon on the Lexicon Forum for this information) 
According to the NSOED's historical information
                                             about the word 'unicorn', "re'em" was Hebrew for 'wild ox'. The accompanying derivation in the NSOED tallies with the above.
                                             
                                             runespoor  
 
 XXXX
 XXXX 
A magical three-headed, snake commonly reaching a length of 6 - 7 feet, coloured livid
                                             orange with black banding; native to Burkina Faso, where several forests are designated as preserves for its sole use. The
                                             runespoor is unique among known magical beasts for producing its eggs through its mouths (FB). 
                                             
Runespoors rarely live to a great age, as each head contains an independent brain serving a different purpose, and they
                                             tend to attack each other. The right head is the planner, the middle head is the dreamer, and the left head is the critic.
                                             The planner decides where the runespoor goes and what it will do next, although the dreamer's visions often lead to a runespoor
                                             remaining stationary for days, lost in its imaginings. The critic, the fangs of which are extremely venomous, hisses continually
                                             (and irritably), evaluating the efforts of the planner and the dreamer. Often, the other two heads will gang up on the critic
                                             and bite it off; two-headed runespoors are not uncommon. 
                                             
The runespoor was once a favorite pet of Dark Wizards, mostly because of its intimidating appearance. The eggs of the runespoor
                                             are used for making potions which enhance mental ability. A flourishing black market in the eggs and in the serpents themselves
                                             has existed for centuries (FB). 
"rune" one of the alternate meanings of this word in English is
                                             'an incantation, a charm, esp. one denoted by magic or cryptic signs; a magic word' [NSOED] 
                                             
salamander 
 
 
XXX 
A small, brilliant white, fire-dwelling lizard that feeds on flame, although it can
                                             survive up to six hours outside a fire if regularly fed pepper (FB, CS8). A salamander lives only as long as the fire from
                                             which it sprang, scampering along burning logs and among the coals, and its colour appears blue or scarlet depending on the
                                             heat of the fire in which it appeared (FB, CS8). Salamander blood has powerful curative and restorative properties (FB). 
                                             
Fred and George once fed fireworks to one just to see what would happen; it was orange (CS8). Hagrid once provided a bonfire full of them for his third year Care of Magical Creatures class (PA12).

XXX 
A gigantic (can grow to a hundred feet in length), snake-like beast with a horselike
                                             head and a long snakelike body rising in humps out of the sea as it moves through the water; found in the Atlantic, Mediterrean,
                                             and Pacific Oceans. The sea serpent has received very bad Muggle press, in this case unjustified. Although many Muggle legends
                                             have grown up around sightings of the creatures, usually tales of horror and death, in reality sea serpents are harmless;
                                             there is no record of a sea serpent ever harming a human. See also the Loch Ness kelpie, which favours taking this form (FB).

A magically-created species of saltwater fish, found in the Atlantic Ocean, which
                                             is covered in spines and which deliberately seeks out and destroys Muggle fishing nets. The first shrake were supposedly created
                                             in the 1800s by a group of wizard fisherfolk who had been insulted by Muggles. The shrake, by damaging the nets used by Muggles
                                             to fish in that area of the sea, cause no end of trouble (FB).

XXXX(the high rating is because of the severe penalties attached to capturing
                                             or owning one) 
A small, spherical bird which can fly with amazing agility, changing speed and direction almost
                                             instantaneously. Its golden feathers and red, jewel-like eyes are so prized that at one time the snidget was hunted almost
                                             to extinction. The fact that a snidget became such an integral part of the game of Quidditch (and usually died when it was
                                             caught) didn't help matters either. The snidget became a protected species; there are now severe penalties for harming or
                                             even capturing one. Snidget reserves have been set up worldwide, and a magical device, the Golden Snitch, has replaced the

Native to Egypt, this human-headed creature has a lion-like body, the capacity for
                                             human speech, and an innate love of puzzles and riddles, but due to its violent tendencies it has been placed in the 'beast'
                                             rather than the 'being' category (FB). 
                                             
The sphinx has been used by wizarding folk for centuries to guard treasure, and is noted for violence when that which it
                                             guards is threatened (FB). In the opinion of the Bestiary's assistant editor, the sphinx is very probably a wizard-bred species rather than a naturally
                                             occurring one, given the remarks made by Scamander in his footnote on acromantulas (FB), but we have no definite information on that point. 
                                             
A female sphinx was stationed in the Triwizard maze both to guard the closest approach to the center and to provide a hint
                                             about the last monster guarding the Triwizard Cup. She required an answer to a riddle; once the riddle was solved, she calmly

Gringotts has been known to place Sphinxes to guard some of the vaults, much to the consternation of those who want access

 toads and frogs 
Toads are allowed as pets for students at Hogwarts, but they're out of fashion, so if you have one,
                                             you're likely to be laughed at for it. Nevertheless, Neville has a toad named Trevor, a gift from an older family member (PS6), and there are enormous purple toads in the Magical Menagerie (PA4). Furthermore, judging from Mundungus' story on Harry's first night in Grimmauld Place, toads (at least in bulk) are valuable

tortoise  
 
Dudley threw his tortoise through the greenhouse roof (PS3). 
The gigantic tortoise with jewel-encrusted shell that Harry, Ron, and Hermione saw in the Magical Menagerie was probably
                                             a Fire Crab (PA4). 
 
 
troll 
 
 
XXXX 
There are three types of trolls: Mountain, Forest, and River (FB). Troll language supposedly consists of grunting and pointing (GF7), but that description is courtesy of the Weasley twins, who were attempting to wind up Percy on the subject of his boss'
                                             linguistic ability at the time. 
                                             The Mountain Troll is very stupid. It stands twelve feet tall, with gray skin, a lumpy body, and flat horny feet. It exudes
                                             a powerfully awful smell, "a mixture of old socks and the kind of public toilet no one seems to clean." Its nose is full of
                                             what looks like lumpy, gray glue: troll boogers (PS10). 
                                             
Quirrell, to create a diversion so he could go after the Philosopher's Stone, let a Mountain Troll into the castle on Halloween,
                                             Y11. It wandered around the corridors until Harry and Ron locked it in a girls' bathroom. Right after they did that, they realized
                                             that Hermione Granger was in that particular bathroom, and they had no choice but to charge in after it. With a luckly combination
                                             of derring-do, desperate magic, and sheer dumb luck, they managed to knock it out and save Hermione (PS10). 
                                             
Quirrell, it turns out, has something of a knack for handling trolls. He placed one in the chambers guarding the stone,
                                             knowing he'd be able to knock it out quite easily when the time came. By the time Harry, Ron, and Hermione arrived in that
                                             chamber, the troll was knocked out cold (PS16). 
                                             
Tom Riddle alleged that Hagrid, as a boy, would go into the Forbidden Forest to wrestle trolls (CS17). 
                                             
Dumbledore hired security trolls to guard the Fat Lady after Sirius Black attacked her. These were evidently a different
                                             type of troll than the Mountain variety, since they seemed considerably more intelligent and less smelly. They spent all their
                                             time pacing the corridor in front of the Fat Lady's portrait, giving dirty looks to everyone who happened by and comparing
                                             the sizes of their clubs (PA). Umbridge apparently also hired security trolls to guard the Firebolt she had confiscated from
                                             Harry (OP). 
                                             
Hagrid and Madame Maxime ran into a couple of mad trolls on the Polish border while on their journey to visit the giants
                                             (OP20).

- Delecour is part veela; her wand's core is a hair from the head of her grandmother, a veela. 
The veela are based on a number of sources which describe Eastern European nature spirits
                                             of legend: 
"Vily" are Slovic fairies who can take the form of birds. [web link] 
"Vilas," as they appear in Serbian legends, are "mountain nymphs, young and beautiful, clad in white, with long flying
                                             hair. Their voice is said to resembel that of the woodpecker. They shoot, according to popular belief, dealy arrows at men,
                                             and sometimes carry off children..." (The Fairy Mythology by Thomas Keightley. 1878.) 
The book A Field Guide
                                             to the Little People describes the Vily (singular: Vila) in detail. They are nature guardians, caring for the trees,
                                             streams, and flowers in their domains. They are extremely jealous of beautiful women. Their moods are as changeable as the
                                             weather and they can both cause and cure illnesses. A human who tarries too long in their territory may be shot dead with
                                             arrows or die suddenly from heart attack, lumbago, or by being buried under an avalanche. Vily have fair complexions and curly,
                                             reddish-brown hair which falls to their feet. They wear shimmering white clothing or coverings of green leaves. Interestingly,
                                             those born on Tuesday or Sunday can most easiy see Vily. 
                                             
werewolf 
 
 
XXXXX 
A werewolf is a human who has been infected with lycanthropy [More...]. Winky 
A female house-elf who "belonged" to Mr. Crouch and helped him care for his son. Winky was sacked in August of Y14 and went to work at Hogwarts, but her shame at being dismissed led her to sit miserably by the fireplace and get drunk on
                                             Butterbeer (GF28). The final fate of Crouch and his son at the end of the Triwizard Tournament did not help matters; Dobby has had to use
                                             the Room of Requirement to look after Winky when she has been incapably drunk (OP18).

Native to Tibet,
                                             this tall (up to 15 feet) white-furred humanoid creature may be related to the troll (unlike giants, the yeti fears fire), but as it will attempt to attack and eat any human (or just about anything else, for that matter)
                                             that it meets, no witch or wizard has had an opportunity to study a living yeti at close range. Ironically, however, Tibet
                                             is one of the most persistent offenders of Clause 73 of the International Code of Wizarding Secrecy due to the number of yeti
                                             sightings by Muggles, to the point that a permanent International Task Force is stationed in Tibet to help control the situation
                                             (FB). 
                                             
Yeti were discussed in Harry's second-year Defence Against the Dark Arts class (CS10), as one of Lockhart's books was Year with the Yeti.
