Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 12-13; Anal spines: 0; Anal soft rays: 13 - 14; Vertebrae: 46. Very long upper jaw, very long pectoral fin, and relatively short lower jaw. Head longer than lower jaw; pectoral fin about as long as head. Sixth anal ray of males widened but not elongated beyond the rest of anal fin rays. None of the male dorsal rays elongated beyond the rest of the dorsal fin.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [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): 2.9 ±0.5 se; based on size and trophs of closest relatives

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