Question

how do animals living in Antarctica survive the cold?answer as quickly as possible...

Answer 1

Animals of these countries have thick fur and fat in their own body

Answer 2

Whales, seals and some penguins have thick fat layers. These fat layers act like insulation, trapping body heat in. This is a little like wrapping yourself in a blanket, but on the inside. In some animals this is even further refined, with the animals selectively able to reduce blood flow to the blubber layers.
