Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 6 - 9; Mjukstrålar i ryggfenan (totalt) : 20 - 25; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 18 - 21. Caudal fin rounded. Pelvic fins small.
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).
