Tube building Polychaete that inhabits a thick parchment-like tube that is chitinized internally and externally covered in foramnifera and algae to avoid predator recognition. Tubes can extend up to a meter deep into the sediment, whereas the decorated tube hook only extends a couple of centimeters out of the sediment.
Tube projects from the sediment in the seabed to catch invertebrate prey. Microcarnivore.
Form tube-mats on sand-bottom interface between rock reefs and kelp forests along the California coast. Often abundant in sand patches near rocky areas such as tide pools.Densities of up to 3000 worms/m2 have been found in central California.
