Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 10 - 12; Raios dorsais moles (total) : 11 - 13; Espinhos anais: 3; Raios anais moles: 8 - 10. Bluish grey above, paler below with a silvery sheen; fins blackish brown (Ref. 6633). Juveniles have black blotches on head and body (Ref. 6633). Body tall, compressed. Big mouth with big head and a rough bony ridge across upper part of the gill cover (Ref. 35388).

Adults prefer to inhabit caves and shipwrecks (Ref. 27121). Juveniles congregate below floating objects (Ref. 27121). Usually solitary. Feed on large crustaceans, cephalopods and benthic fishes (Ref. 27121). Spawn in the summer (Ref. 35388). Are primary gonochorists (Ref. 58421). Marketed fresh or frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). Minimum depth reported from Ref. 6633.

Estimates based on models

Preferred temperature (Ref. 115969): 5.2 - 19, mean 9.4 (based on 672 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.8125 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01318 (0.00968 - 0.01796), b=3.00 (2.91 - 3.09), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Nível Trófico (Ref. 69278): 4.1 ±0.64 se; based on food items.

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (K=0.05-0.08; tmax=76; tm=9-10 yrs estimated from VBGF; Fec=3 million).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (78 of 100).

Climate Vulnerability (Ref. 125649): Moderate to high vulnerability (50 of 100).

Categoria de preço (Ref. 80766): Low.
