Grindylow

A grindylow is a small, horned, pale-green water demon and a dark creature.

Appearance
Grindylows are a sickly green color with green teeth and small pointed horns on their heads. They have long, strong, and brittle fingers which they use to strangle their prey. They are particularly good swimmers.

Behavior
Grindylows are aggressive toward all types of human beings, except Merpeople, which they have been tamed by. Grindylows are even sometimes kept as pets by Merpeople.

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

Habitat
Grindylows are found in the weed beds at the bottom of lakes in Great Britain and Ireland. They are particularly prevalent in Yorkshire, where they display a large amount of physical variation. It is generally found in still or stagnant water. In more recent years, Grindylows have taken to urban environments, such as Porter Beach in the heart of Sheffield, where they shelter in submerged shopping trolleys and traffic cones.
