Video by @nickcobbing | Polar bear cubs play-fighting on Arctic Ocean sea ice. The blood on their fur is from a recently devoured seal, which has likely provided the energy for this kind of play. From observing the wider family group, we’re pretty sure these two are from the same family of three cubs (the third is just out of frame). It’s rare to see three cubs at any time so it was great to see these siblings make it through to their second year, well fed and playing happily. A rare sighting indeed! The video was shot just a few weeks ago at the ice edge above Svalbard, from a small ship held in the ice nearby. Sea ice across the Arctic Ocean is experiencing a record low extent, in the Barents region where this video was captured, there is now a huge distance between the mainland and the summer sea ice. These cubs are fortunate because their mother has done an amazing job in keeping them well fed; she found the ice quickly and has used it to hunt productively. Whether future generations of polar bears will adapt to the effects of climate change on sea ice is a big area of study right now. Most biologists I speak to venture that it’s simply not possible for polar bears to adapt to an eventual loss of their habitat. It’s not a good time for any of the species that are reliant on the sea ice ecosystem.
