Keep up: This polar bear mum picks up her cub during a 35-mile trek to Canada's Hudson BayIt's a scene with which many parents will empathise.
A tired youngster drags their heels after spending a long, hard day traipsing around behind mum. In the case of this polar bear cub however, mum has enough and decides to take matters into her own hands or rather teeth. She picks up her beleagured cub in her mouth and powerfully swings it in front of her before dropping it back down on the ground.
This amazing sequence of pictures captures the family as they set out on a huge trek from their winter den to the sea ice and food in Canada's Hudson Bay.
The bears weigh less than two pounds at birth and fatten up on their mother's rich milk. After emerging from their den they spend a few days growing stronger before the trip to the ice. They will then be with their mother for the next two and a half years as she teaches them how to hunt for seals.
