PEANUT WORMS Phylum SIPUNCULIDA

Distinctively non-segmented, a peanut worm body consists of two vaguely defined regions. The extendable introvert (neck) has a tentacle-rimmed mouth designed for deposit feeding. The remainder of the body (trunk) is cloaked by a tough, rubbery wall. Extending into each region, the long coiled digestive tract culminates in a dorsally positioned anus, located just behind the mouth.
Approximately 21 species of peanut worms live in the marine waters of the Pacific Northwest.
