Biology     Glossary (e.g. epibenthic)

Species' maximum length from the Belgian part of the North Sea (Ref. 7882). Depth and length based from occurrence record; to be replaced with better reference. Inhabits sandbanks and muddy bottoms of estuaries and inshore areas (Ref. 96352) and along the near-coastal zone. A tube-dwelling bristle worm, preferring fine to coarse sediment with 10 to 40% mud content. Its flexible tube, longer than the worm itself and made up of cemented sand grains and shell fragments, allows it to withdraw inward and the tube to subsequently bend down (Ref. 7882). A filter- and suspension feeder (Ref. 75621). Capable of surface deposit feeding (Ref. 87179). Feeds on organic detritus (Ref. 96352) and small invertebrates (Ref. 87179). 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).
