Indo-Pacific and Western Atlantic.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Minimum depth from Ref. 112705. This is a tubiculous species found at depths of 25 to 75 m (Ref. 87801). Larger species feed by filtering plankton and organic particles from the water column while smaller species can pick up organic matter from the sediments and filter feed organic matter (Ref. 107862).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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.
