Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 9 - 12; Espinhos anais: 0; Raios anais moles: 14 - 16. Brownish above, sides silvery, iridescent, with black peritoneum showing through (Ref. 7344).

Meso- and bathypelagic at 700-1830 m (Ref. 58302). Probably swift swimmers, which can avoid nets, captured singly or in small groups (Ref. 6692). Carnivorous, feed on squids and pelagic fishes (Ref. 6692). Oviparous and are synchronous hermaphrodites (Ref. 84733).

Life cycle and mating behavior Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas

Are synchronous hermaphrodites, gonads consist of clearly defined and well separated ovarian and testicular regions with no indication of sequential maturation of the sex products (Ref. 84733). Also Ref. 103751.

Estimates based on models

Preferred temperature (Ref. 123201): 4.8 - 21.3, mean 10.5 °C (based on 2379 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.5000 [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).

Nível Trófico (Ref. 69278): 4.3 ±0.64 se; based on food items.

Resiliência (Ref. 120179): Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (Assuming tm=2-4).

Fishing Vulnerability (Ref. 59153): Low vulnerability (18 of 100).
