Eastern Atlantic: Canary Islands (Ref. 6808), 20°N (inshore from 29°N) to about 10°S west of 0°, with disjunct distribution between 14°N and 8°N, but to 23°S east of 0°. Isolates north to off south-west Ireland (Ref. 4775). Western Atlantic: tropical areas but with expatriate extensions to 51°N and 45°S in western boundary currents [(apparently absent over a minimum region off Brazil) according to Ref. 4479 or 4775] (Ref. 4479, 4775). Very rare or absent in the Indo-Pacific. Tropical Indian and Atlantic; east coast of South America (Ref. 47377).

High-oceanic and mesopelagic populations are found between 225-750 m during the day (maximum abundance at 450-500 m) and is nyctoepipelagic at surface down to 125 m at night (Ref. 4479). Pseudoceanic and pelagic populations are found in the upper 50 m at night (Ref. 4066). Feeding is acyclic in northwest Africa (Ref. 9198).

Estimates based on models

Preferred temperature (Ref. 123201): 6.5 - 13.9, mean 9.6 °C (based on 46 cells).

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00741 (0.00455 - 0.01207), b=3.00 (2.86 - 3.14), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.0 ±0.00 se; based on food items.

Generation time: 0.6 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resiliência (Ref. 120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (K=1.83-3.81; tm=0.7; tmax=1.2).

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