The bearded seal (Erignathus barbatus) or square flipper seal, is a medium-sized seal 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 Linnean 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. Distinguishing features include square foreflippers and thick bristles on their muzzles. Adults are greyish-brown in colour, darker on the back, rarely with a few faint spots on the back or dark spots on the flanks. Occasionally the face and neck are reddish-brown. Bearded seal pups are born with a greyish-brown natal fur with scattered patches of white on the back and head. Bearded seals are unique in the subfamily phocinae in having two pairs of nipples, a feature they share with monk seals.
Bearded seals are large seals, reaching about 2.25 to 2.7m (89 to 106 inches) in nose-to-tail length and from 275 to 340 kg (606 to 750 lb) in weight. Both genders are about the same size.
The bearded seal is a primary food source for polar bears and for the Inuit of the arctic coast. The Inuktitut name for the seal is Ugyuk or Oogrook. The seals skin is used to cover a wooden frame boat (Umiak).
The body fat content of a bearded seal is 30-40%.
