The tundra is home to a variety of animals, including:
* Arctic foxes
* Arctic hares
* Caribou
* Musk oxen
* Polar bears
* Ptarmigans
* Reindeer
* Seals
* Snowy owls
* Walruses
* Wolves
These animals have adapted to the harsh conditions of the tundra in a variety of ways. For example, many animals have thick fur or feathers to keep them warm. Some animals, such as the Arctic hare, have changed the color of their fur to match the snow in order to camouflage themselves from predators. Other animals, such as the caribou, have large hooves that help them to distribute their weight evenly on the soft ground.
The tundra is a fragile ecosystem that is threatened by climate change. As the global temperature rises, the permafrost is melting and the growing season is getting longer. This is causing changes in the plant and animal life of the tundra. Some species are moving northward in search of cooler temperatures, while others are becoming extinct.
