HistoryEdit

Professor Remus Lupin ordered a Grindylow in 1993 for his third year class to study for Defence Against the Dark Arts. After his resignation, he left behind the tank in which the Grindylow was kept.^[4]

Two years later, the Grindylows of the Black Lake at Hogwarts School of Witchcraft and Wizardry attacked the students competing in the 1994-1995 Triwizard Tournament. They caused the early retirement from the task of Fleur Delacour, and nearly killed Harry Potter.

BehaviourEdit

Aggressive towards witches and wizards and muggles alike, the Grindylow has only ever been tamed by merpeople; the half-fish beings keep them as pets.

DietEdit

Grindylows survive, for the most part, on fish, algae, and small sea creatures; however, occasionally they will eat humans (it is for this reason that they are classified as dark creatures).

HabitatEdit

These creatures are found in the weed beds at the bottom of lakes in Great Britain and Ireland.

Physical appearanceEdit

The Grindylow is a sickly green colour, with green teeth and small pointy horns on its head. It has long, strong (albeit brittle) fingers which it uses to strangle its prey, and is a rather good swimmer.

DefenceEdit

The Grindylow has long, brittle fingers which despite their fragility are rather strong. The trick to escaping a Grindylow is to break their grip on a person; it can also be noted that the Revulsion Jinx may help with this task, as underwater it shoots jets of boiling hot water.

Behind the scenesEdit

• In the film adaptation of Harry Potter and the Goblet of Fire, the grindylow is a small creature with tentacles and two dangling tentacles on its head. In the book, there is no such description.
• The term "grindylow" was often used interchangeably with the term "hag" in Old English folklore.^[5]
