Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 7 - 9; Raggi dorsali molli (totale) : 17 - 20; Spine anali: 0; Raggi anali molli: 12 - 15. Caudal fin rounded.
A resident intertidal species with homing behavior (Ref. 32612) found in shallow rocky areas (Ref. 2850). Commonly found in tide pools, often in algae (Ref. 2850). Can leave tide pools when aquatic conditions become inhospitable (Ref. 31184). Breathes air when out of water (Ref. 31184).
