Primarily [[benthic]], bearded seals feed on a variety of small prey found along the ocean floor, including [[clam]]s, [[squid]], and [[fish]]. Their whiskers serve as feelers<ref>Saundry, Peter. 2010.

Adults tend not to dive very deep, favoring shallow coastal areas no more than {{convert|300|m|abbr=on}} deep. Pups up to one year old, however, will venture much deeper, diving as deep as {{convert|450|m|abbr=on}}. In a study conducted during the summer months, the seals have been found to feed on invertebrates such as [[anemones]], [[sea cucumbers]], and [[polychaete worms]].<ref name="Finley"/> The same study found that sculpins and [[arctic cod]] made up most of their summer diet. [[Sculpin]] were also found to be the largest fish consumed by the seals. Bearded seals are capable of preying on pelagic and [[demersal]] fish in addition to their benthic prey.<ref>{{Cite journal|last=Finley|first=K. J.|last2=Evans|first2=C.
