Palatal teeth in two oblique, oval patches; one on each side of palate, well separated. Snout acute; lips fleshy, crenulate; lower jaw truncate. Head shield granular; dorsomedian head groove lanceolate, narrow distally. Eye large, 17-28% HL. Large, flattened serrae along inner margin of pectoral spine; caudal fin lobes slender, acute. Rakers present along posterior face of all gill arches. Distinct, blackish margin on dorsal, pectoral and inner caudal fins (Ref. 40908).

Estimates based on models

Preferred temperature (Ref. 123201): 27.4 - 29.2, mean 28.7 °C (based on 674 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.4 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (34 of 100).
