Sixteen abdominal segments with uncinigerous neuropodia, first two abdominal uncinigerous tori of thoracic-type lacking dorsal cirri and posterior 14 abdominal neuropodia of different shape and with dorsal cirri. Rudimentary notopodia absent. Abdominal uncini similar to thoracic ones, with 2 vertical rows of 3 teeth above rostrum. Pygidium with two lateral cirri and about 10 capitate papillae.

Life cycle and mating behavior Chín muồi sinh dục | Sự tái sinh sản | Đẻ trứng | Các trứng | Sự sinh sản | Ấu trùng

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.
