Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 3; Radios blandos dorsales (total) : 13 - 15; Espinas anales: 1; Radios blandos anales: 7 - 9; Vértebra: 27 - 29. Branchiostegal rays: 8-8 (Ref. 36655).

A mesopelagic species, found primarily below 200 m depth (Ref. 36655). All studied specimens were reported to have been sampled by nonclosing gears from the depth of more than 2000 m that one cannot conclude about the exact sampling depth and the depth range of this species; notably, larger specimens occur deeper than young ones (Ref. 117119). Oviparous, with planktonic eggs and larvae (Ref. 36655).

Estimates based on models

Preferred temperature (Ref. 123201): 4.6 - 12.4, mean 5.5 °C (based on 13 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00442 - 0.02595), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.4 ±0.2 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
