Climate / Range
Indo-Pacific, Northeast Atlantic and the Mediterranean.
A filter feeder (based from the feeding ecology of the family Serpulidae; Ref. 87179). Occurs at depths between 50 to 200 m, in areas of silt to very fine sand (Ref. 96391). Found near hydrothermal vents (Ref. 905). Attached epifauna (Ref. 3123). 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).
