Family Phocoenidae (Porpoises)

IDENTIFICATION
Dall's Porpoise is easily identified by the prominent white patch on each side; it also has white markings on the dorsal fin and upper trailing edge of the flukes. Its robust midsection is unlike that of any other marine mammal in the eastern Pacific. The dorsal fin is slightly curved, but almost triangular. Adults can grow more than two metres long and weigh up to 218 kg. Newborn calves are approximately 30 cm long.

MEALS, MANNERS AND MIGRATION
Dall's Porpoises eat squid, crustaceans and fishes such as capelin, mackerel, herring and anchovies. They are normally found in groups of 2 to 15, although pods of over 500 have been sighted. They are fast swimmers, reaching speeds of more than 50 km per hour (27 knots). Dall's Porpoises move erratically, darting about and making swift, sharp turns, but they rarely leap.

STATUS
COSEWIC has designated Dall's Porpoise as not at risk. Although many die after becoming entangled in fishing gear, this species is considered common and its population does not appear to be declining.

DISTRIBUTION
Restricted to the cool waters of the North Pacific Ocean and the Bering Sea. Dall's Porpoise is typically found in offshore waters, but it frequently inhabits the deep inland waterways of British Columbia. It is a year-round resident in Hecate Strait, Laredo Channel, Queen Charlotte Sound, Goletas Strait and Juan de Fuca Strait.
