The bearded seal is a primary food source for polar bears and for the Inupiat Eskimo of the arctic coast. The eskimo name for the seal is Oogrook. The seal skin is used to cover a wooden frame boat (Umiak).
The movements of the true seals upon the ground or ice are very different from those of the eared seals, or Otariidae, which walk and run upon all four feet, the body being raised as in the case of ordinary quadrupeds.
Although the true seals do not possess the beautiful under-fur (seal-skin of the furriers) which makes the skin of the sea-bears or fur-seals so precious, their hides are still valuable as articles of commerce, and together with the oil yielded by their fat, subject them to a devastating persecution.
Other species of seals inhabiting the nothern seas, of which stragglers have occasionally visited the British coasts, are the small ringed seal or floe-rat of the sealers (Phoca hispida), the Greenland or harp-seal (Phoca groenlandica), the hooded or bladder-nosed seal (Cystophora cristata) and the beardedseal (Phoca barbata).
The true seals or earless seals are one of the three main groups of mammals within the seal suborder, Pinnipedia.
It should be noted that the common seal (harbor seal in the U.S.), Phoca vitulina, does not separate foraging and maternal investment; instead, it displays a reproductive strategy similar to those of otariids, in which the mother makes short foraging trips between nursing bouts.
This allows the mother seal to maximize the efficiency of her energy transfer to the pup and then quickly return to sea to replenish her reserves.
