Animals living in the mountain regions are also adapted. Such adaptations are basically to protect them from cold and snow. For example, yak has thick skin covered with fur to protect it from cold. Mountain goat has thick fur on its body including feet and toes. These animals have strong hooves for running up rocky slopes of the mountains.
- The oxygen content in the mountain air is thin. So the blood of most of these animals contains more red blood cells. This helps them to breathe in sufficient oxygen even when air pressure is low.
- Some animals hibernate or go for a long winter sleep when the temperatures are very low. In this way they conserve their energy and survive the winter without food. Frogs, and hedgehogs are some animals which hibernate.
