Longueur à la première maturité / Taille / Poids / Âge
Maturité: Lm 40.6, range 36 - 45.72 cm
Max length : 76.0 cm TL mâle / non sexé; (Ref. 2850); âge max. reporté: 18 années (Ref. 43439)
Common inshore, in tide pools or shallow rocky areas, from the intertidal zone to 24 m depth. May remain out of water under rocks or seaweed (Ref. 31184). Feeds mainly on crustaceans and algae. Breathes air (Ref. 31184) and can remain out of water for 15-35 hours if kept moist (Ref. 51276). Demersal spawners in nearshore habitats (Ref. 56049). Oviparous (Ref. 205). Commonly caught by 'poke-poling', a method using a long bamboo pole with a very short wire leader and baited hook. Good eating.
