Sessile; depth range 0 - 72 m (Ref. 865)

Western Central Atlantic and Eastern Pacific.
Size refers to tube diameter (Ref. 865). Reef-building, tubiculous polychaete (Ref. 100429). Colonies form on and against rocks, particularly in areas of high sand transport (Ref. 865). Planktotrophic larvae explore the substrate for possible settlement depending on a chemical stimuli (Ref. 100429). Reproduction is strictly sexual (Ref. 100409). Broadcast spawner. Larval settlement at metamorphosis are dependent on the availability of adult's cemented sand tubes (Ref. 100443). Plantotrophic larvae undergo an 18-day pelagic development at 20Â°C; afterwards they begin to explore the substrate for possible settlement; it is positively phototactic and an active swimmer, upon development of its tentacles it becomes positively geotactic and crawls on the substrate in search of settlement. Its tentacles are used for anchoring and exploring the substrate (Ref. 100429).
