Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 4 - 5; Anal spines: 0; Anal soft rays: 9; Vertebrae: 44 - 45. Differentiated from its congeners by the following unique set of characters: eye diameter 1.9-3.2% HL; interorbital distance 19.2-25.1% HL; snout length 28.6-34.1% HL; length of caudal peduncle 33.7-36.5% SL; 44-45 vertebrae; and brown spots on the dorsal and pectoral fins concentrated in a dark band in the distal half (Ref. 45707).

Sexually dimorphic (Ref. 45707).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [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).

Trophic level (Ref. 69278): 4.3 ±0.7 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).
