The polar bear – like many cold-climate animals – is much bigger than its bear relatives living in warmer lands. An adult male can weight a ton and stand 10ft tall on its hind legs. The polar bear’s main prey are seals and it spends most of its time at sea, either on ice floes or in the water, hunting.
