They have a two part body with an anterior prosoma consisting of a bulbous proboscis, a short collar, and a mouth armed with short hooks. The second body part is a warty trunk. All species are marine and are mostly found in shallow water.
Some species burrow into sand and mud, others live in crevices in rocks, or in empty shells.
Others bore into rock. The body is completely unsegmented. Tree of Life - Sipuncula . A classification of the Sipuncula with a photograph. Introduction to the Sipuncula .
