Aysheaia has ten body segments, each of which has a pair of spiked, annulated legs. The animal is segmented, and looks somewhat like a bloated caterpillar with a few spines added on — including six finger-like projections around the mouth and two grasping legs on the "head." Each leg boasts a subterminal row of about six curved claws.[1] No jaw apparatus is evident.[2] The pair of legs marks the posterior end of the body, unlike in onychophorans where the anus projects posteriad; but this may be an adaptation to the terrestrial habit.
