A female polar bear and her cub rest on an ice floe after a swim. The bears are not tied to a specific territory, but roam widely in their search for food, often leapfrogging from iceberg to iceberg. Bears fitted with satellite collars have been tracked on swims of up to 240km across open oceans. In some habitats, disappearing sea ice is forcing polar bears to make longer, riskier swims.
