Bearded Seal

 

(Erignathus barbatus), a pinniped of the family Phocidae. It measures 2.2–2.6 m long and weighs 225–360 kg. The pelage is grayish brown, sometimes with a few light spots on the back; the pelage of the newborn is dark. The bearded seal inhabits the arctic regions of the Atlantic Ocean, the Sea of Okhotsk, and the White, Barents, Kara, Chukchi, and Bering seas. It usually lives solitary in shallow waters and reproduces in the spring on drifting ice. It feeds on bottom invertebrates; more rarely, on fish. The bearded seal is a valuable object of commerce.
