Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais (total) : 8 - 13; Espinhos anais: 0; Raios anais : 15 - 25; Vértebras: 44 - 51. Body slender and compressed. Anal fin base long and about twice the length of dorsal fin base. Eye diameter about twice snout length. Upper end of gill slit reaching above midline of side of body. No knob-like process in interorbital space. Dorsoposterior edge of operculum not curved inward. Traces of detached scales black. Color black or dark brown; bluish black on head and ventral surfaces, and on peritoneum (Ref. 6885).
Does not undertake a diurnal, vertical migration. Feeds heavily on crustaceans (Ref. 4525). Oviparous, with planktonic eggs and larvae (Ref. 35604). Minimum cdepth from Ref. 028981.

Estimates based on models
Preferred temperature (Ref.
123201): 0.4 - 5.2, mean 3.2 °C (based on 91 cells).
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00458 - 0.01316), b=3.07 (2.92 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Nível Trófico (Ref.
69278): 3.3 ±0.42 se; based on food items.
Generation time: 7.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resiliência (Ref.
120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (K=0.14 (very tentative estimate)).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (52 of 100).
Nutrients (Ref.
124155): Calcium = 29.9 [10.3, 96.3] mg/100g; Iron = 0.365 [0.142, 1.282] mg/100g; Protein = 13.7 [10.4, 17.9] %; Omega3 = 0.395 [0.118, 1.350] g/100g; Selenium = 21 [7, 55] μg/100g; VitaminA = 38 [5, 303] μg/100g; Zinc = 0.672 [0.358, 1.397] mg/100g (wet weight);
