Ecology of Septifer bilocularis

Main Ref.	Poutiers, J.M., 1998
Remarks	Frequently found in areas exposed to washing of surf with strong water current (Ref. 80041). Attached to rocks, dead corals or the underside of stones, sometimes occurring in dense colonies. Littoral and sublittoral to a depth of about 15 m (Ref. 348). Living among the alga Corallina officinalis in rock-pools between tide-marks (Ref. 88739). Reported from Hong Kong to be found on the ceilings and walls of submarine caves (Ref. 126058).
