Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 12; Rayons mous dorsaux (Total): 14-17; Épines anales 2; Rayons mous anaux: 13 - 15. Juveniles are reddish orange above, with small bright blue spots on forehead and dark spots at upper pectoral fin base, dorsal fin, and caudal peduncle; colors disappear as fish grows larger (Ref. 26938). Adults dark gray to blackish with vertical black lines on body; a black spot, sometimes diffuse, at upper base of pectoral fins which are pale; other fins dark (Ref. 13442).

Biologie     Glossaire (ex. epibenthic)

Adults inhabit rocky shores exposed to wave action. Often in tide pools. Feed primarily on algae and detritus. Territorial and pugnacious. Generally common (Ref. 9710). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Taken incidentally in traps and small-meshed beach nets (Ref. 5217).
