Burmeister's porpoises frequent inshore bays, channels, and fjords, [1] but individuals have been spotted as far as 50 km (31 mi) from the shore and in the freshwater Valdivia River in southern Chile. [1] Though normally found in continental shelf waters, they have been found as deep as 1,000 m (3,300 ft) [1]
Porpoises, and other cetaceans, belong to the clade Cetartiodactyla with even-toed ungulates. Porpoises range in size from the vaquita , at 1.4 metres (4 feet 7 inches) in length and 54 kilograms (119 pounds) in weight, to the Dall's porpoise , at 2.3 m (7 ft 7 in) and 220 kg (490 lb).
