Short description
Identification keys | Morphology | Morphometrics
Vertebrae: 27. This species is distinguished from all congeners by having an elongated spot of black melanophores along the caudal-fin branched rays, not distinctly connected to the lanceolate plates at the base of the fin. The spot is extended over a larger number of lower-lobe rays than upper-lobe rays and along one-half to more than two-thirds of the ray length (Ref. 84367).
Facultative air-breathing in the genus (Ref. 126274); Feeds on algae (Ref. 13371).
