Ankheg

A gigantic, man-eating centipede that lives in deserts and wastelands. Even as a larva, it is as big as an adult human, and it grows even bigger each time it sheds. A ferocious hunter known for its tremendous speed afforded by its many legs, it mainly attacks by biting with its tough jaw, or by spitting acid at its enemies. When attacking a group, they are known for displaying a division of roles, where some wrap up their enemies while others bite.
