Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 9-11; Anal spines: 0; Anal soft rays: 8 - 9; Vertebrae: 37 - 38. Diagnosis: body depth 6.65-7.2 times in SL (Ref. 89136), 11.9-15.5% SL, with greatest depth at or slightly anterior to dorsal fin (Ref. 81636). Head length 4.1-4.8 times in SL (Ref. 89134, 89136), 17.9-22.7% SL (Ref. 81636). Snout length 2.65-3 times in HL (Ref. 89136). Eye dorsolateral (Ref. 81636, 89136), 3.85-4.8 times in HL, 1.4-1.8 times in snout length (Ref. 89134, 89136), 1.1-1.5 times in interorbital distance (Ref. 89136). Interorbital distance wide, 27.8-43.4% HL (Ref. 81636). Dorsal fin origin 1.15-1.2 times further from snout tip than from caudal fin origin; anal fin origin 1.85-2.15 times further from pelvic fin origin than from caudal fin origin (Ref. 89136). Pectoral fin enlarged and paddle-shaped (Ref. 81636), 4.5-5.1 times in SL (Ref. 89134, 89136), 0.9-0.95 times longer than head (Ref. 89136). Pelvic fin 6.2-7 times in SL, 1.35-1.5 times in HL (Ref. 89136). Both pectoral and pelvic fins fan out from body in the horizontal plane formed by the ventral surface (Ref. 81636). Caudal peduncle 1.4-1.7 times longer than deep (Ref. 89134, 89136).

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=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
