Photo by @paulnicklen | A ringed seal approaches the surface of one of the many holes it created in the sea ice. Ringed seals can remain underwater for up to 45 minutes, but when there is no access to open water, they use these holes, which are maintained year-round, to come up for air. However, they must be cautious, as polar bears will often sit patiently above the holes, awaiting the arrival of a vulnerable ringed seal. #FollowMe at @PaulNicklen for more photos from our planet’s polar regions. #Arctic #seal #seaice #wildlife
