neonofarm [45]

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.

Some of those adaptations are:

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

- stockier bodies so that heat can be preserved easier
