What are the adaptations to the icy tundra?

Organisms in the icy tundra have developed several adaptations to survive harsh conditions. Many plants, like mosses and lichens, have low growth forms to resist strong winds and a thick insulating layer of snow. Animals, such as the Arctic fox and polar bear, possess thick fur and a layer of fat for insulation against the cold. Additionally, some species exhibit seasonal camouflage, changing their fur or plumage to blend in with the snowy environment, aiding in predator evasion and hunting.
