Occurs in intertidal areas and to 37 m depth, but more common in subtidal areas (Ref. 2850). Often found among algae (Ref. 2850). Adults inject eggs into the tissue near the gastral cavity of a sponge to use as a spawning bed (Ref. 34818).
External fertilization with internal insemination (Ref. 37516). Adults inject eggs into the tissue near the gastral cavity of a sponge to use as a spawning bed (Ref. 34818).
