Length based on occurrence record; to be replaced with better reference. Inhabits upper layer of muddy-sandy substrate in sheltered areas (Ref. 2780). Found along the coastal zone, preferentially in fine-grained to muddy sediment (Ref. 7882). Mobile burrowing detritivore (Ref. 95752). Deposit feeders; burrows up to 15 cm below and then everts its papillose sac-like pharynx during feeding (Ref. 87179). It is known as a head-down/subsurface deposit-feeder (Refs. 96214, 96292, 96501). 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).
