Maximum depth from Ref. 116516. Species' maximum length from the Belgian part of the North Sea (Ref. 7882). Length based on occurrence record; to be replaced with better reference. Found on volcanic mud at a depth of 823.5 m in the Azores (Ref. 78667). In the North Sea off Belgium, inhabits coastal to open sea zones, typically in coarse sediment; absent in muddy substrates (Ref. 7882). Both a carnivore and detritivore (based from the feeding ecology of the family Glyceridae; Ref. 87179).
Life cycle and mating behavior
Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
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.
