Many of them have larger bodies and shorter arms, legs and tails which helps them retain their heat better and prevent heat loss.
How Arctic animals survive in freezing temperature?
How are animals adapted to life in Antarctica?
Physical adaptations are sometimes the easiest to spot. Many of the animals living in Antarctica have outer layers of dense fur or water-repellent feathers. Under this fur or feather layer is a thick layer of insulating fat. Many marine animals have large eyes to help them spot prey and predators in the dark waters.
