Species' maximum length from the Belgian part of the North Sea (Ref. 7882). Maximum depth from Ref. 107252. Found in estuarine and inshore areas associated with organic pollutants (Ref. 96352). A tube-living bristle worm found along the near-coastal zone in a variety of sediments often in areas of fine to medium-grained sediment with a high mud content. The tube has a fan-shaped top and a grouping of several tubes form "sand reefs" (Ref. 7882). A surface deposit-feeder (Ref. 96292) and an interface-feeder (Ref. 96376). Feeds on organic detritus (Ref. 96352). Members of the class Polychaeta are mostly gonochoric (sexual). Mating: Females produce a pheromone attracting and signalling the males to shed sperm which in turn stimulates females to shed eggs, this behavior is known as swarming. Gametes are spawned through the metanephridia or body wall rupturing (termed as "epitoky", wherein a pelagic, reproductive individual, "epitoke", is formed from a benthic, nonreproductive individual, "atoke"). After fertilization, most eggs become planktonic; although some are retained in the worm tubes or burrowed in jelly masses attached to the tubes (egg brooders). Life Cycle: Eggs develop into trocophore larva, which later metamorph into juvenile stage (body lengthened), and later develop into adults (Ref. 833).
