Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

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).

Biology     Glossary (e.g. epibenthic)

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 of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00759 (0.00365 - 0.01576), b=3.01 (2.82 - 3.20), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.00 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (K=1.83-3.81; tm=0.7; tmax=1.2).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Price category (Ref. 80766):   High.
