髯海豹

The bearded seal (Erignathus barbatus), also called the square flipper seal, is a medium-sized pinniped that is found in and near to the Arctic Ocean. It gets its generic name from two Greek words (eri and gnathos) that refer to its heavy jaw. The other part of its Linnaean name means bearded and refers to its most characteristic feature, the conspicuous and very abundant whiskers. When dry, these whiskers curl very elegantly, giving the bearded seal a "raffish" look.

Range

Bearded seals have a circumpolar Arctic and sub-Arctic distribution. In Canada they are found throughout Hudson Bay and eastward, along the coast of Labrador to northern Newfoundland. Vagrants have been reported in the Gulf of St. Lawrence and elsewhere.

Life Cycle

Pups are born on drifting ice floes, usually in shallow water, in May (in the Canadian Arctic; earlier elsewhere in their range). Pups first swim just hours after birth; by the time they are weaned, at about 24 days, they are spending half of their time in the water. The pups, relatively large when born, grow at an average rate of 3.3 kg per day in those first three to four weeks.
