How do caribou survive in the taiga biome?
The taiga is frequently covered in snow. To move quickly and effectively through snow, some animals’ feet have evolved for better traction and footing. The caribou has large hooves, with two extended toes called “dew claws.” The increased size of the caribou’s feet allows them a stable foundation on which to walk.
What are some caribou adaptations?
These adaptive traits include having large, fur-covered hooves for gripping the ice as they make their way across the frozen landscape in their annual migrations. They also have a warm, thick coat to protect them from both extreme cold in winter and insect attacks in summer.
What species of caribou are in Alaska?

How do caribou help the environment?
Caribou are an important resource for indigenous peoples, a prey species for carnivores and omnivores, such as bears and wolves, and a critical source of nutrients for the soil in areas where they forage in large numbers. They are also the only deer species where males and females both have antlers.

They are well adapted to living on the tundra. Their large, spreading hooves support the animal in snow in the winter and marshy tundra in the summer.
