An A-Z of Fantastic Beasts - Grindylow; M.O.M. Classification: XX

A horned, pale-green water demon, the Grindylow is found in lakes throughout Britain and Ireland. It feeds on small fish and is aggressive towards wizards and Muggles alike, though merpeople have been known to domesticate it. The Gryndylow has very long fingers, which, though they exert a powerful grip, are easy to break.

 Acromantula

The Acromantula is a monstrous eight-eyed spider capable of human speech. It originated in Borneo, where it inhabits dense jungle. Its distinctive features include the thick black hair that covers its body; its legspan, which may reach up to fifteen feet; its pincers, which produce a distinctive clicking sound when the Acromantula is excited or angry; and a poisonous secretion. The Acromantula is carnivorous and prefers large prey.

An A-Z of Fantastic Beasts - Basilisk (also known as the King of Serpents); M.O.M. Classification: XXXXX

The first recorded Basilisk was bred by Herpo the Foul, a Greek Dark wizard and Parselmouth, who discovered after much experimentation that a chicken egg hatched beneath a toad would produce a gigantic serpent possessed of extraordinarily dangerous powers. 
The Basilisk is a brilliant green serpent that may reach up to fifty feet in lenght. The male has a scarlet pluma upon its head. It has exceptionally venomous fangs but its most dangerous means of attack is the gaze of its large yellow eyes. Anyone looking directly into these will suffer instant death.
If the food source is sufficient (the Basilisk will eat all mammals and birds and most reptiles), the serpend may attain a very great age. Herpo the Foul’s Basilisk is believed to have liced for close on nine hundred years.
The creation of Basilisks has been illegal since medieval times, although the practice is easily concealed by simply removing the chicken egg from beneath the toad when the Department for the Regulation and Control of Magical Creatures comes to call. However, since Basilisks are uncontrollable except by Parselmouths, they are as dangerous to most Dark wizards as to anybody else, and there have been no recorded sightings of Basilisks in Britain for at least four hundred years.
