Acromantula have eight immensely long, hairy legs that can span over 15 feet. With their eight eyes and a pair of shining black, razor-sharp, poisonous pincers, they are a beast to be reckoned with. Acromantula pincers make loud clicking noises, though the species is also capable of human speech.
Acromantula lay around 100 eggs, that take around 8 weeks to hatch. They live in dome shaped webs which they make on the floor. They prefer the dark and quiet, and hunt large preys. The female spider is larger than the male, and can reach heights similar to that of small elephants. Like all other spiders, they fear the Basilisk above all else.

Ashwinder:
The Ashwinder is a thin, pale-gray serpent with red eyes that is created if a magical fire goes unchecked.

While the creature lives for only an hour, great damage can be done if it goes undetected. The eggs are so hot, they can set fire to the dwelling they are located in. To prevent this from happening, eggs can be frozen with a freezing charm. Frozen Ashwinder eggs are a love potion ingredient.

Augurey: (Irish Phoenix)
Looking somewhat mournful, it is not surprising that the Augurey can utter a heart-rendering sound. This small bird lives in a tear-shaped nest and feeds of insects and fairies. When the Augurey sings, you can be sure that rain is approaching. Rainy days are also best to spot this animal as it is extremely shy and only flies during rain.
Since the Augurey is a native creature of Britain and Ireland, they aren’t very useful as a pet because of their constant moaning when it is raining. Collecting their quills isn’t useful either as they repel ink. De mystery that used to surround the Augurey in earlier years made this creature quite famous; Uric the oddball owned fifty pet Augureys. The Augurey is also the star in “Why I didn’t die when the Augurey Cried” by Gulliver Pokey.

The first recorded Basilisk was bred by Herpo the Foul, a dark wizard from Greek decent, and known parselmouth. Being able to speak parselmouth is the only known way to control this seprent that can reach up to fifty feet in length. Male Basilisks, unlike the females, have a scarlet plume on top of their head.

Blast-Ended Skrewts:
Recently hatched Blast-Ended Skrewts look like deformed, shell-less lobsters, horribly pale and slimy looking with legs sticking out in very odd places with no visible heads. They are about six inches long and give off a very powerful smell of rotting fish. Some of them have stingers. Others have blood sucking openings on their bellies. After a couple of months, they develop a kind of thick, grayish shiny armour and grow to about three feet long. They are immensely strong and very hard to control at this point. At this stage, they look like a cross between giant scorpions and elongated crabs without recognizable heads or eyes. Blast-Ended Skrewts propel themselves by blasting sparks out of their rear ends. They can grow to ten feet long. In order to stun a Blast-Ended Skrewt, a witch or wizard must cast the spell at its fleshy, shell-less underbelly as it will not penetrate the thick armour.

Centaurs live in herds, from up till 50 members. They are highly intelligent, and are only marked by the Ministry of Magic as “beast” by their own request. Centaurs are extremely suspicious of both muggles and wizards alike, so most of their ways are shrouded in mystery, but they are known to be skilled in archery, astronomy, divination and magical healing. Centaurs can be banished from their herd if they do not follow the rules of the herd. Helping humans or doing anything which may be considered as servitude to humans or passing their knowledge and secrets to humans is considered a crime. Centaurs do not touch the innocent and believe that the killing of foals is a terrible crime. A centaur considered to have betrayed and dishonored the herd may receive corporal punishments or even death. The species is said to have originated in Greece, but can be found all over Europe.

These pustules flash colours when the Clabbart senses danger, and therefore makes the animal unfit to be kept as a pet kept outside in the garden.

The Crup eats virtually everything it can get it’s teeth in, and are therefore known to be great scavengers.
In order to keep a Crup as a pet, a wizard will have to obtain a license from the Ministry before being allowed, proving that one can control the Crup in Muggle inhabited areas. To avoid detection, the Crups forked tail is mandatory to be removed at 6 weeks old, with a painless severing charm.

Dragons:
Dragons weight several tons and can become as tall as fifty feet. Dragons can shoot fire at a range of at least twenty-feet, and their bogers sizzle. Their ear splitting roars can be heard far away. They are extremely difficult to slay, owing to the ancient magic that imbues their thick hides, which none but the most powerful spells can penetrate. It takes at least half a dozen wizards to knock out a dragon with a Stunning Spell. The eyes of the dragon are the weakest. If a wizard can hit a dragon in the eye with a spell, that spell may be successful. Effective spells include the Stunning Spell and the Conjunctivitus Curse. Mother dragons keep their eggs hot by breathing fire on them. Baby dragons can be fed by wizards with a mix of brandy and chicken blood. Though, it should be noted that dragon-breeding is outlawed by the Warlocks’ Convention of 1709. It is rumored that dragons guard the high security vaults at Gringotts. (A rumour later confirmed) There are twelve uses of dragon’s blood as discovered by Albus Dumbledore and his partner, Nicholas Flamel. Dragon manure is very good soil fertilizer. Dragon hide is used to make clothes, boots, and gloves. The heartstrings of dragons can be used as wand cores. Dragon livers and dung are available at wizard apothecaries. Since Dragons are so hard to hide from Muggles, the Ministry has their hands full keeping Dragons in specially appointed areas that have anti-muggle protection. Dragon species, ten in all, are able to interbreed, creating rare hybrids.

It is more intelligent than other creatures with similar looks, like the Imp, Doxy or Pixie, but shares their love for mischief. Intelligent as the Leprechaun is, and capable of speech, they never have requested the Ministry to be re-classified as Beings rather than beasts.
The Leprechaun is a good natured mischief maker, and has as far as knonw, never caused lasting damage to a humam. They live in woodland and forest, and bear their young live. Due to it’s love for Muggle attention, the Leprechaun features in many a Muggle childrens book.

Lethifold:
Another name for Lethifold would be “Living Shroud”. It owes that name to it’s form; a black cloak like figure of about half an inch that glides along the ground. A thicker Lethifold probably just killed and is now digesting it’s victim.
Lethifolds live in tropical climates, and like the Dementor, can only be repelled by the use of a Patronus. Sadly, the Lethifold hunts at night and attacks the sleeping, so they rarely have a chance to actually use magic.
The lethifold suffocates it’s prey and digests it at the spot, leaving no trace behind. It has been known to be abused by Wizards, who pretended to have become victim of the Lethifold to get out of tight spots.

Merpeople:
British Merpeople have grayish skin and long, wild, dark green hair, yellow eyes and often broken teeth. However, the Merpeople vary in appearance just as much as humans so and the more pretty forms can often be found in more tropical waters. It is those Merpeople so often spotted in Muggle literature.
Merpeople are an ancient species, that have declined “being” status much like Centaurs did. They are intelligent and have their own language, which is understandable underwater, but sounds screechy out of the water.
Merpeople’s jewerly consists of thick ropes of pebbles. They also carry spears and might use Lobalugs as weapons as well.
They live in organized communities, sometimes comprised of crude stone dwellings stained with algae. Some houses have gardens of weeds around them. Merpeople paint pictures on some of the underwater rocks and hew statues from boulders. Merpeople have been known to domesticate grindylows. There is a community of Merpeople in the lack at Hogwarts School of Witchcraft & Wizardry, but can be found all over the world. Different names for Merpeople are Selkies, Merrows and Sirens.

Phoenix:
The phoenix is a crimson bird the size of a swan with red and gold feathers. The phoenix has a glittering golden tail with feathers as long as a peacock’s. It has gleaming golden talons, a long sharp golden beak and beady black eyes. Its wide, scarlet wings emit a soft golden glow in the darkness. When it is time for a phoenix to die, it bursts into flames and is reborn from the ashes. It can carry immensely heavy loads, and its tears have healing powers. The song of the Phoenix inspires bravery and courage to those who hear it, though not of those not pure of hear, they will experience fear instead. The phoenix is a highly faithful pet, but extremely hard to domesticate. Like a house-elf, the magic of the Phoenix is not bound by Hogwarts protective spells, the Phoenix is able to apparate and disapparate at will, in a flash of fire. A witch or wizard can disapparate with the phoenix by touching it as it disapparates. The phoenix sleeps with its head under its wing. The tail feathers of a phoenix may be used as the core of a wand.
Phoenixes breeds in China, Egypt and India where it nests on mountain peeks. This good-natured creature has never been reported to harm someone and eats only herbs.

Quintaped:
A creature shrouded in Myth. The Quintaped is also referred to as  a ‘Hairy MacBoon’ due to the myth that surrounds this five-legged brown-haired low-slung bodied vicious beast. They only are found on the Island of Drear, at the north eastern top of Schotland. Because of the nature of the Quintaped, this island has been made unplottable.
Tales tell that the island was once inhabited by two rivaling wizarding families, the McCliverts and the MacBoons. The McCliverts, far more advanced at magic than the MacBoons, resolved a wizarding duel gone bad for their side, by transfiguring every single MacBoon into a five legged monster, but realised too late that the vicious creatures they created were far too dangerous. The now monsterous MacBoons retaliated by slaughtering every single McClivert and forever more refusing to be transfiguered back to humans.
No one knows if the myth is true, and the Quitapeds themselves have never allowed any ministry wizard close enough to attempt to transfigure them back into humans, so we must assume were they really MacBoons, they are quite happy living their lives as carnivorous beasts.

Runespoor:
The Runespoor originates in Burkina Faso, and is a three headed serpent with a livid orange color, and black stripes. Because the heads are venemous, and the Runespore is so easy to spot, the Ministry of Magic in Burkina Faso has designated areas for the Runespoor to live, and made those unplottable.
This creature can grow up to 7 foot long and has long since been the favorite pet of Dark Wizards, most likely because of it’s appearance and poison.
The runespoor can communicate with parseltongues because it is a serpent, and has 3 heads, each with an individual purpose. The right head is most annoying of all, critisizing the other two head constantly. The middle head is the dreamer, Runespoors are known dreamers, and can remain stationary for a very long time, lost in dreams. The left head is the planner, and decides the Runespoors goals and moves.
Unlike any other magical creature, the Runespoor produces its eggs in its mouths. The eggs are used in potions that stimulate mental processes.
Because the Runespoor and its eggs are so valuable, there has long since been a black market for Runespoor trading.

Such witches and wizards are very rare and are known as Parselmouths. Snakes alsways had a curious affiliation with Dark Wizards. Perhaps because the first and most well known Wizard able to speak Parseltongue, was Salazar Slytherin himself. They can be found as ornaments in many a Dark Wizards house, from snake formed door knobs to snake-like lamps.

Trolls tend to live in the mountains, in Poland and the Forbidden Forest according to Tom Riddle, but they originate in Scandinavia. Nowadays they can be found in other areas of Northern Europe as well. There are three different species of Trolls: The mountain, forest and river troll. Mountain Trolls have dull, granite grey skin, and a great lumpy body like a boulder with a small bald head perched on top like a coconut. They have short legs thick as tree trunks with flat, horny feet. Forest Trolls differ slightly from the Mountain Troll; their skin is greenish, and they sometimes have green or brown hair. River trolls are slightly purple, grow horns and might have hair.
Trolls are at least twelve feet tall. They smell like a mixture of old socks and the kind of public toilet that no one seems to clean. Trolls are strong, but stupid. They grunt instead of talk and carry clubs. Trolls can be taught simple things to become, for example, guardians.  This is however, not very advisable as Trolls are highly unpredictable and extremely stupid.
It is difficult to penetrate the skin of a troll with a Stunning Spell, and the Troll itself is not a very picky eater, they eat raw flesh, whether it be animal or human.

Unicorn horns are used in potions and are available at apothecaries. Unicorn hairs can be used as wand cores. Unicorn blood is silver and has magical qualities. The blood of a unicorn will keep an individual alive, even if an inch from death, but at a terrible cost. From the moment the blood touches the lips, that individual will have a cursed life, a half-life.
Like the Fairy, the Unicorn is often featured in Muggle literature.

Werewolves:

Werewolves are identified by the shapes of their snout, the pupils of their eyes and tufts of their tails. Werewolves transform during the full moon and are only a danger to people, not animals. One becomes a werewolf when bitten by one. The technical term for the conditions is lycanthropy. Twenty years ago, there was no cure for lycanthropy. Gilderoy Lockhart claims he was able to cure someone in Wagga Wagga suffering from lycanthropy using an incredibly complex Homorphus Charm. The recently discovered Wolfsbane Potion, taken during the week preceding the full moon, makes werewolves safe while they transform as they keep their minds. It is very painful to transform. Werewolves are mistrusted by most wizards resulting in tremendous discrimination. Such discrimination includes anti-werewolf legislation making it impossible for wizards suffering from this condition to obtain employment. There is also the 1637 Werewolf Code of Conduct.
While completely sane during the rest of the month, at full moon the werewolf will generally prefer human pray over any other and will seek human company.Werewolves choose to align themselves with Lord Voldemort, a choice that most likely will not do their reputation any good.Known werewolves are, amongst others, Professor Remus J. Lupin and Fenrir Greyback.Werewolves may life in the Forbidden Forest at Hogwarts. First year students at Hogwarts learn different ways to treat werewolf bites.
