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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00891 (0.00451 - 0.01762), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 2.0 ±0.00 se; based on food items.

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
