Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 13; Raggi dorsali molli (totale) : 11 - 12; Spine anali: 2; Raggi anali molli: 11 - 12. Adults gray brown dorsally, often shading white ventrally, with purple- blue markings, many as vertical lines; upper edge of eye bright purple-blue; juveniles blue (Ref. 13442).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Adults occur in steep outer slopes and deeper patch reefs (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).
