Ways to idenitfy this species: largest seal found in Alaska region, coloration brown or silver-gray, long whiskers and rounded flippers
Biology
- Found in seas next to Alaska including the Bering, Chukchi and Beaufort.
- Usually
keeping to themselves, they are only observed together when there is a
reduced amount of ice in the summer that forces them to concentrate in
certain areas. They are only migratory in their pursuit of ice.
- These
seals can weigh up to 750 lbs during the winter but they lose
significant weight during the spring and summer, dropping up to 425
lbs as a result of less feeding.
- The bearded seal eats a variety of fish and invertebrates such as crabs, shrimp and clams.
- Female
bearded seals have one pup at a time but become pregnant again within
two weeks after the pup is weaned. Scars on males are most likely
attributed to fighting during breeding season
- During
the breeding period in the spring, adult male seals “sing” underwater.
This whistle is sometimes audible to humans and can alert hunters to
their location.
Threats- Although
the bearded seal is hunted for food and hide by native Alaskans, the
most serious threat to this ice-dependent species is global warming,
which is destroying its habitat.
