Grikshak

A Grikshak is an animal native to the Klingon world of Boreth. It was considered one of the most deadliest predators native to its homeworld and had no fear of humanoids which it could easily dispatch with its fearsome claws and fangs. Even a juvenile could reach the size of a Human Grizzly bear which showed how large these beasts could be.

These animals possessed an azure coat of fur, however, a bright blue coat shows that the Grikshak is a juvenile as the adult females of the species possess a silvery blue coat. This allowed perfect camoflage among the blue grasses of the animals surroundings. It sniffed its surroundings and its prey with its black wet nose.
