# Cold-Weather Adaptations

Understand how polar animals are adapted to survive extreme cold — blubber (thick fat layer) insulates seals and whales, hollow fur traps air for warmth in polar bears, counter-current heat exchange in penguin flippers prevents heat loss, Arctic foxes grow thick white winter coats for camouflage and warmth, and some animals migrate to avoid the harshest months
