Spirobranchus lamarcki

Description

Spirobranchus lamarcki is a species of tube-building annelid worm which is widespread in intertidal and sub-littoral zones around the United Kingdom and northern Europe. They are found attached to firm substrates, from rocks to animal shells to man made structures, and often are noted for their detrimental effect on shipping. It is closely related to, and often confused with, Spirobranchus triqueter.
