Eastern Atlantic and Mediterranean Sea: Positively known only from Madeira, Sicily (Italy), Strait of Gibraltar, and the adjacent Atlantic Ocean off southern Portugal. Can be expected to range widely in the eastern and perhaps central North Atlantic. Central and eastern Atlantic records from Japanese longliner's data need clarification. Highly migratory species.

Estimates based on models

Preferred temperature (Ref. 123201): 14.3 - 19.1, mean 17.1 °C (based on 37 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5630   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00193 - 0.01034), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  4.3   ±0.4 se; based on size and trophs of closest relatives
Resiliência (Ref. 120179):  Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
