Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 9; Anal soft rays: 7; Vertebrae: 34. Distinguished from its congeners by the following characters: lower pectoral ray count (22 vs. 23-28); wider head, width 4.1 in SL (vs. 4.2-5.3); short snout, 3.7 in HL (vs. 2.8-3.5); shorter disc, 6.2 in SL (vs. 4.2-5.2); and possession of irregular dark bars on the body (Ref. 75094).

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): 3.2 ±0.2 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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