==Description==
European fan worms grow to a total length of and are usually larger in deep water. They have stiff sandy tubes formed from hardened mucus secreted by the worm which protrude from the sand, and a two-layered crown of feeding tentacles which can be retracted into the tube. One of the layers forms a distinct spiral. The colour of the tentacles is variable but they are usually banded in orange, purple and white or they may be a uniform pale grey. Various epiphytic organisms settle and grow on the tubes which may be rather wrinkled near their bases.
