A male Polar Bear has gone days without eating and the pungent smells coming from a low lying island, that is currently inhabited by hundreds of walrus, lures the bear to the island. Mature walrus are huge animals and weigh a ton. Their skin is extremely thick and their tusks can be a meter long. The polar bear has lost half his body weight during the summer and is very hungry. The battle is on. It’s not gonna be easy.
Filmed and produced by BBC Planet Earth.
