Climate / Range
Subtropical; 22°C - ? (Ref. 12451), preferred 27°C (Ref. 107945); 47°N - 39°S, 99°W - 20°E (Ref. 55219)
Distribution
Atlantic Ocean: roughly from 45°N to 45°S in the southwestern Atlantic and 35°S in the southeastern Atlantic. Records from the Mediterranean Sea, and from Bretagne, France seem to correspond to a few straying individuals. Classified as 'reduced' (Ref. 12451). It is unclear whether there are two separate stocks or a single population in the Atlantic. Highly migratory species, Annex I of the 1982 Convention on the Law of the Sea (Ref. 26139).
