animals- that have thick layer of blubber or fur

The characteristics of polar animals are adapted to allow survival in freezing and sparse vegetation ecosystems. The northern and southern polar animals are different. However, in both cases, animals have tried to adapt to the inhospitable and truly extreme circumstances of their surroundings.
