Distribution. Cold-temperate waters of the Southern Hemisphere, mainly at 20-60° S except on both coasts of South America, where they occur at most lower latitudes. Concentrated in winter near the coastlines off S Australia, New Zealand, Atlantic coast of South America (Argentina, Brazil), and S Africa (mainly South Africa), but also off Chile, Peru, Tristan da Cunha Is and the E coast of Madagascar; in summer they are found mainly in latitudes of 40-50° S but have been seen in the Antarctic as far as 65° S and around South Georgia Is. in Balaenidae
