Biologi     Ordlista (t.ex. epibenthisk)

Inhabit inshore areas associated with organic pollutants, in silty to very fine sand substrate (Ref. 96352) and muddy bottoms (Ref. 2780). A surface deposit feeder (Ref. 96435)/microvore that feeds on organic detritus (Ref. 96352). Sessile. Use tentacles to feed (Ref. 125928).

Livscykel och parningsbeteende Könsmognad | Reproduktion | Lek | Ägg | Fekunditet | Larver

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.
