Biology     Glossary (e.g. epibenthic)

Depth is based on occurrence in Qatar (Ref. 107130); to be replaced with a better reference. Abundant under overhangs, rock slabs and boulders in the lower eulittoral subzone. Builds a white calcareous tube in a uniquely clockwise spiral that is 1 cm across (Ref. 102838). 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).
