@weonaroll: A man was filming the depth of a hole in Arctic ice when he accidentally caught a seal surfacing to breathe He was filming how deep the hole went, and a seal came up for air in it. That hole is not random, it is a seal's front door. 🦭❄️😮 Ringed seals cut and maintain their own breathing holes using the thick claws on their front flippers, through sea ice six feet thick or more. They keep several open across an area so a polar bear cannot simply camp on the only exit. The seals dive to around 300 feet and can stay under for up to 45 minutes before they need one of those holes. Thinning Arctic sea ice takes that whole system away, which is why ringed seals are treated as a bellwether species for climate change.
