Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 5 - 7; Raios dorsais moles (total) : 33 - 36; Espinhos anais: 2 - 3; Raios anais moles: 31 - 34; Vértebras: 40 - 43. First dorsal spine longer than second dorsal spine. Opercles fully scaled (Ref. 27159). Female adult chocolate brown in color with darker fins; prejuveniles silvery with numerous dark spots of various sizes which become larger with age (Ref. 6548).

Inhabit continental slopes of all southern continents (Ref. 6545). Adults found near the bottom; juveniles near the surface, usually in association with krill (Ref. 5194). Feed mainly on salps (Ref. 27150). Eggs float near the sea surface and larvae also inhabit surface waters (Ref. 6390). There is no vertical migration during the day or night (Ref. 27150).

Estimates based on models

Preferred temperature (Ref. 115969): 2.1 - 6.1, mean 4.2 (based on 189 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01995 (0.00816 - 0.04876), b=3.00 (2.79 - 3.21), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.6 ±0.47 se; based on food items.

Resiliência (Ref. 120179): Muito baixo, tempo mínimo de duplicação da população maior que 14 anos (K=0.07; tmax=100; tm=31; Fec=6,000).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (72 of 100).

Climate Vulnerability (Ref. 125649): Moderate vulnerability (39 of 100).

Categoria de preço (Ref. 80766): Medium.
