Reproductive type (?) | Sexual References: Walker, A. J. M. 1972. Goniadella gracilis, a polychaete new to British seas. Marine Biology, 14, pp. 85-87. Comments: 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 |
Developmental trait (?) | Brooding Comments: 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. |
