Peanut Worm Golfingia vulgaris
The peanut worm is shaped like a half-inflated sausage balloon. Its body is stout and has a long, thin region at the front called the introvert, which can be stretched right out or withdrawn completely inside the body. The animal has a crown of short tentacles around the mouth at the end of the introvert. It lives buried in sediment, which it eats as it burrows and digests any organic matter.
