I won't settle

Aries: Ashwinder. These beasts emerge from magical fires and only live for 24 hours. In that time they slither into the woods to lay their eggs and then turn to ash. Their eggs are extremely valuable to Love Potions. Ashwinders take the form of pale-grey serpents with glowing red eyes. They are found worldwide.

Taurus: Bowtruckle. A Bowtruckle is tree guardian found mainly in German, English and Scandinavian forests. They are extremely small and very hard to see as they blend in with the trees they protect. They appear to be made of bark and twigs and have two small brown eyes. They are peaceful creatures until their tree is threatened, in which case they will gouge out the attackers eyes with their claws.

Gemini: Demiguise. There isn't much information known about Demiguise creatures because they are very shy and have the ability to make themselves invisible when they feel threatened. They take the form of graceful apes and they are especially known for their silvery hair which can be spun into invisibility cloaks. They are often found in the Far East. 

Cancer: Antipodean Opaleye. These creatures are actually very small dragons and considered to be the most beautiful out of all the dragon species. They are known for their iridescent, pearl coloured scales and their multi-coloured eyes. Even though they produce magnificent scarlet flames, Opaleyes are the least aggressive dragons and will only kill if they are hungry or extremely frightened. They are typically found in New Zealand. 

Leo: Fwooper. These magical birds are commonly found in Africa and are famous for their exceedingly vivid plumage. Their feathers range from fire-orange, bright pink, lime green and golden yellow. They are extremely dangerous creatures because their songs (though beautiful) can drive the listener to insanity. 

Virgo: Kneazle. Kneazles are small cat-like creatures with spotted fur, overly large ears and the tail of a lion. They are extremely intelligent and just as independent but can become aggressive if they don't trust someone. They have the uncanny ability to detect suspicious characters and can always be relied on to take their friends to safety if they are lost. They are often found in Britain.

Libra: Nundu. This creature is arguably the most dangerous creature in the wizarding world. Resembling an enormous leopard, these beasts are often over-looked by Muggles. However, a single breath from a Nundu can create such a virulent disease that it can wipe out an entire village in one fell swoop. It is hard to track Nundus as they are so silent and are incredible at remaining unseen. They are mostly found in Africa.

Scorpio: Lethifold. Lethifolds take on the shape of a thick black cloak. They glide along forest floors looking for prey and if something is unlucky enough to meet one, the Lethifold will quickly glide over its prey and suffocate it to death. It then digests its prey on the spot and leaves no trace of its victim behind. The only way to repel one is a Patronus charm. They are extremely rare and are only found in tropical climates.

Sagittarius: Pixie. These creatures are described as being tiny, electric blue humanoids. They delight in tricks and are very mischievous. It is still a mystery as to how they are able to fly (they have no wings) but they use this to their advantage as it helps them pull of more complicated jokes. Their voices are said to sound like high pitched jabbering to human ears. They are found in England. 

Capricorn: Manticore. This creature is a class XXXXX, meaning it is highly dangerous and should never be approached, trained, or domesticated. It has the head of a man, body of a lion and tail of a scorpion and is reported to lure its prey in with soft coos and songs. Once it has sight of its prey, it devours it whole. A sting from a Manticore's tail is instantly fatal. It is also nearly impossible to kill as its hide repels all known charms. It is found in Greece.

Aquarius: Grindylow. These creatures are quite frightening and are commonly found in lakes in Britain and Ireland. Taking the form of pale-green water demons, Grindylows generally feed on raw fish and are extremely aggressive towards both Muggles and Wizards. They are often seen around merpeople and were the reason Fluer Delacor had to forfeit during the second challenge of the Triwizard Tournament. 

Pisces: Mooncalf. These creatures are intensely shy and only emerge from their burrows during a full moon. They are described as having pale grey skin, large eyes and four spindly legs with large flat paws. They perform extremely complicated dances in the moonlight and if a wizard were to collect their silvery dung and spread it on their herb or flower beds, the plants would grow very fast and become uncommonly strong. These creatures are found worldwide.
