Biología     Glosario (por ej. epibenthic)

Lives in tubes under rocks on open shores and bays, near low tide line and below in shallow water (Ref. 87872). Feeds on fine organic particles (Ref. 87872); main food is detritus, including diatoms, unicellular algae and small invertebrates (based on the feeding ecology of the family Terebellidae; Ref. 87179).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

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.
