Morphology

edit

It has a spindle-shaped front body, changing to a more cylindrical form at the back end. The prostomium has four eyes and two long palps. The peristomium has four short, finger-shaped and four longer, threadlike gills. All gills are often retracted into the body. Body colour varies from pearl-grey to silver-white with a length up to 25 mm.[2]

Ecology

edit

It lives on the ocean floor where it digs tunnels that are supported by slime secreted from the worm. Here it feeds on detritus and microorganisms.
