Predominantly intertidal, occasionally found subtidally. Adults may be found in a mucous tube, under boulders or on holdfasts of algae (Ref. 111185). Omnivorous, feeding on plant detritus, algae, and sometimes on harpacticoid copepods and amphipods (Ref. 108780).
Life cycle and mating behavior
بلوغ | تولید مثل | تخم ریزی | Eggs | Fecundity | Larvae
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). The worms die after their breeding period (Ref. 111269). Also Ref. 111267.
