Tube-living bristle worm with a cylindrical body up to 100 mm long. The head features a crown of six
short, branched and membraneous gills. The segments number 30 and differ in length. The flexible
tube of cemented sand grains and shell fragments is longer than the worm itself. The worm is able to
withdraw from the end protruding from the sediment surface, which subsequently bends down.
