Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 14; Raggi dorsali molli (totale) : 12 - 14; Spine anali: 2; Raggi anali molli: 12 - 14. Overall color is black. With three pupil-size white spots: one at the rear base of the dorsal fin, one at the rear base of the anal fin, and the third at mid-base of the caudal fin.
Body shape (shape guide): short and / or deep; Cross section: compressed.
Adults form large aggregations high above the bottom in rocky areas around caves and ledges (Ref. 7247). Benthopelagic (Ref. 58302). Collected from 183 m. Spawn from December to June (Ref. 7247). 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).
