Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Raios dorsais (total) : 52 - 55; Espinhos anais: 0; Raios anais : 34 - 40. Pectorals rounded, pedunculate (Ref. 6885). Generally of a chocolate color (Ref. 6885). Young more robust, with an expanded and rounded caudal fin, 5 pelvic rays, and a brown and yellow irregularly blotched with faint purple color, dusky on fins (Ref. 6885).

Adults occur near bottom; juveniles in shallow water or offshore near the surface (Ref. 50277). Feeds on jellyfish (Ref. 50277), fishes and squids (Ref. 2850), as well as octopuses (Ref. 4525).

Estimates based on models

Preferred temperature (Ref. 115969): 2 - 14.1, mean 6.2 (based on 1370 cells).

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 1.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 4.5 ±0.57 se; based on food items.

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (K=0.13; Fec=293,000).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (71 of 100).
