What r some adaptions that animals who live in the alpine biome survive

The animals that live in the Alpine biome have to have special adaptations to survive in it as this is a biome with very harsh conditions for big portion of the year. The temperatures are very low, the winds are strong, winter lasts for half a year or more, and there's lot of snow. All this has made the animals to develop certain traits to help them survive. Some of those adaptations are:

- thicker and longer fur for better isolation form the outside conditions

- wider paws with denser and tougher skin, helping them to move easier in the snow and avoid frostbite

- larger lungs and nostrils for easier breathing in the high altitudes

- stockier bodies so that heat can be preserved easier

- the ears and tails are small and rounded in order to avoid frost bite

- big portion of them are able to hibernate for several months
