Swimming Great Male Polar Bear | Planet Earth | BBC Earth
The male polar bear's ice world has finally vanished beneath him.
While the female is still kept on land by her dependent cubs, the male can take to the sea in search of food.
Ducking and diving, he hopes to ambush seals, resting on the remaining fragments of ice.
In these new surroundings, he is a surprisingly adept swimmer.
Once an extremely rare sight, polar bears have recently been seen over 60 miles from the shore.
There is now no turning back for this bear.
He's forced to head out into deeper water.
His giant front paws help him to fight the ocean currents.
He seems at home in the sea, but he cannot swim indefinitely.
He will drown if he doesn't find land somewhere in this vast ocean.
