▲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.

Bearded seals give birth in the spring. In the [[Northern Canada|Canadian Arctic]], seal pupping occurs in May.<ref name="uoguelph"/> In Svalbard, bearded seals reach [[sexual maturity]] at 5 or 6 years of age.<ref>Andersen, Magnus, et al. "[https://brage.bibsys.no/xmlui/bitstream/handle/11250/174308/AndersenPolarBiol1999.pdf?sequence=1 Growth, age at sexual maturity and condition in bearded seals (Erignathus barbatus) from Svalbard, Norway]." Polar Biology 21.3 (1999): 179-185.</ref> Further south, in [[Alaska]], most pups are born in late April.{{clarify|reason=See talk page|date=March 2013}} Pups are born on small drifting ice floes in shallow waters, usually weighing around {{convert|30|–|40|kg|abbr=on}}. They enter the water only hours after they are born, and quickly become proficient divers. Mothers care for the pups for 18–24 days, during which time the pups grow at an average rate of {{convert|3.3|kg|abbr=on}} per day. During this time, pups consume an average of {{convert|8|l|abbr=on}} of milk a day. By the time they are weaned, the pups have grown to about {{convert|100|kg|abbr=on}}.
