Anatomy
Caudofoveata are worm-like molluscs ranging 0.02–10 cm in size, but one species, Chaetoderma felderi, can reach 36.5 cm. The foot is completely absent, and instead of a shell their mantle is covered in calcareous spines called sclerites.

Ecology
Caudofoveates live by burrowing through soft sediment, and feed by lying vertically in the sediment with just the mouthparts exposed and taking in passing organic detritus. During sexual reproduction, the female produces eggs which are fertilized and brooded, and then the larvae swim freely.
Diet
Caudofoveates are deposit feeders, or more selective detritivores or predators of foraminifera.
