Rückenflossenstacheln (insgesamt): 12; Rückenflossenweichstrahlen (insgesamt): 18; Afterflossenstacheln 2; Afterflossenweichstrahlen: 18 - 19. Skin naked and slimy. No tentacles on the head. Dip in the middle of dorsal fin. Variable coloration (Ref. 35388).
Facultative air-breathing (Ref. 126274); A resident intertidal species with homing behavior (Ref. 32612) found in shallow waters of rocky coasts. May remain out of water under rocks or seaweeds (Ref. 31184). Mostly active at daytime during high tide. Breathes air when out of water (Ref. 31184). Feeds on small benthic invertebrates, especially gastropods, barnacles and amphipods, and algae (Ref. 31184). Also, diet of crabs, polychaetes, isopods, copepods, limpets, mussels and small molluscs (Ref. 94105). Oviparous (Ref. 205). Eggs measuring 1.5 mm (Ref. 35388) are demersal and adhesive (Ref. 205). Spawning takes place in April - August (Ref. 35388).
Oviparous, distinct pairing (Ref. 205). Male guards eggs from several females (Ref. 5981).
