In the polar regions, from the vast 'moderate' taiga as in Canada north to the Ice seas, and in ice-only Antarctica, seasons are extreme in day length - and resulting climatic contrast, forcing many animals to migrate. So mating and breeding is very intense and demanding for many species, such as polar bears. The ice 'lives' spectacularly too, even helps steer worldwide currents and weather. The unending struggle for survival is particularly merciless. The less known ice seas are no less rich in extraordinary, well-adapted wildlife.
