Next to the thin polar bear and her cub, the sleeping walruses look enormous.

They were spotted by Travis Wilkinson in July of 2015 just after midnight. Because they were in Svalbard, a Norwegian archipelago in the Arctic north, it was still light enough for Wilkinson to capture the bears on video.

He and his family were in the middle of a sailing trip. In the days prior, they had been farther north, but as they sailed south, the ice began to loosen and eventually transitioned into water. Wilkson says the route, sometimes impassable, was particularly free of ice that summer.

In his video, you can see the mother bear approach the sleeping walrus, cub following at her heels.
