Diet
The bearded seal uses its sensitive whiskers to locate prey like fish, crabs, shrimp, clams and snails.
Life Cycle
The bearded seal mates in May. Groups of up to 50 bearded seals may gather together. Males sing to attract females and males occasionally fight over a female. The female gives birth to a single pup 11 months later. The pup weighs about 70 pounds at birth and its eyes are open and it is covered in blue to brown fur. The pup can swim shortly after birth and quickly puts on weight. It nurses for
12 to 18
days. By the time the nursing period is over, it will have almost tripled its weight to about 185 pounds. The female will mate again two weeks after her pup is weaned.
Behavior
Except for breeding season, the bearded seal is a solitary animal.
In the spring, male bearded seals "sing" underwater songs that can be heard by humans on the surface. The song is probably used to attract a mate and establish territory.
