Aysheaia
''Aysheaia'' was a genus of Cambrian-aged soft-bodied, caterpillar-shaped fossil organisms with average body lengths of 1–6 cm. ==Anatomy== ''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. No jaw apparatus is evident.〔 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.〔
