Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 7 - 9; Radios blandos dorsales (total) : 17 - 20; Espinas anales: 0; Radios blandos anales: 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).
