Overview

Comprehensive Description

Description

 A stout, cylindrical worm up to 20 cm long that lives permanently in a thick, transparent, mucilagenous tube that remains almost completely buried in soft sediment. The head, which projects from the tube, is surrounded by a crown of purple and brown tentacles that are interlaced for most of their length, forming a characteristic funnel, with only their tips free. The body is segmented and dark yellow or orange in colour.  When disturbed the worm retracts into its tube and can reduce its length by half.Myxicola infundibulum may occasionally be found in conditions of variable salinity such as inlets and harbours.
