The hitcher crab was a crustacean native to the deserts of Sevarcos II. They moved around the desert, and ate plants and smaller animals. A slow-acting poison coated their claws and shell, used both to disable prey and to discourage predators. With medical treatment, the poison was generally non-fatal for Humans. The Sevari often hunted them, both for their nutritious meat, and for their large water sacs. Hitcher crabs became full-grown adults at 15 standard years.
