Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 12; Rayons mous dorsaux (Total) : 15 - 16; Épines anales: 2; Rayons mous anaux: 13. Anal fin long and pointed, reaching well beyond base of tail (Ref. 26938). Adults dark gray-brown, the edges of the scales blackish; a wash of yellowish often present dorsally on head, nape, and on back below spinous portion of dorsal fin; a small black spot at upper base of pectoral fins; juveniles bright yellow with two bright blue lines dorsally on head, extending to beneath middle of dorsal fin where they break into spots; a large blue-edged black spot basally on dorsal fin centered on last spine (Ref. 13442).
Adults inhabit coral and rocky reefs of sheltered lagoons and inshore areas. Territorial and pugnacious (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).
