The alpine biome is a harsh environment and not many living creatures can survive. It is cold, snowy and windy and the temperature can get well below freezing. Due to the thin atmosphere, UV rays are stronger and more harmful.
The vicuña is a member of the camel family that is specially adapted to the severe alpines in the Andes, Chile. Their extremely thick coat traps warm air and helps them keep warm in freezing temperatures. The vicuñas’ lower teeth grow constantly, so that they can chew the tough grass that grows on the mountains. They chew the grass while resting so they get more nutrients.
