Mesopelagic species (Ref. 559). Migrates to the surface at night and return to the depths at dawn. Feed mainly on small fishes and crustaceans (Ref. 4525). Oviparous, with planktonic eggs and larvae (Ref. 35926). Exhibit extreme sexual dimorphism, with larvoid males (Ref. 35926).

Estimates based on models

Preferred temperature (Ref. 123201): 1 - 22.5, mean 11.7 °C (based on 216 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [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).

Trophic level (Ref. 69278): 3.8 ±0.60 se; based on food items.

Generation time: 2.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100).

Preiskategorie (Ref. 80766): Unknown.
