Polar

Real parks and dive sites where wildlife from this ecosystem lives.

The extreme regions of the Arctic and Antarctic, with permanent or seasonal ice and whole months of light or darkness. Much of life depends on the sea rather than the land: the water's productivity supports birds and marine mammals that breed on solid ground or on the ice. Thermal insulation — blubber, dense plumage, fur — and making the most of a very short summer are the keys to survival.
