Morphology | Morphometrics
Distinguished by the following characteristics: general body color is light grey-brown, typically have areas of very bright iridescent blue and/or yellow; body is laterally compressed; large, nearly vertical mouth; completely scaled body; first dorsal with VII spines; ventral fins are united (Ref. 92840).
Inhabits shallow water on soft calcareous bottoms. Found usually near burrow, but occasionally seen swimming in small schools.
