tundra fauna

Tundra fauna includes animals adapted to the cold, harsh environment of polar and subarctic regions. These creatures, such as Arctic foxes, caribou, snow hares, and various birds, have special features like thick fur, fat layers, and behaviors that help them survive extreme cold, limited vegetation, and seasonal changes. Many migrate or hibernate to conserve energy. Predators like wolves and polar bears hunt the smaller animals, maintaining ecological balance. Despite the extreme conditions, tundra supports a delicate but resilient ecosystem where each species plays a vital role in sustaining the environment.
