Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 14; Rayons mous dorsaux (Total) : 12 - 13; Épines anales: 2; Rayons mous anaux: 12 - 13. Overall color is brown; posterior edges of dorsal caudal, and anal fins lighter.
Adults inhabit steep slopes and rocky bottoms mainly on offshore reefs (Ref. 7247). Diurnal species (Ref. 52881). 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).
