Here are two different ways to say how these animals keep safe from extreme weather:
Way 1: To keep cool in hot weather, camels keep water stored in their humps, elephants move their big ears to cool off, and jerboas stay safe by hiding in underground homes called burrows. To stay warm in cold snowy places, the Arctic fox grows thick fur, and the walrus has a thick layer of blubber to keep heat inside.
Way 2: When it's very hot, camels save water inside their humps, elephants cool down by flapping their ears, and jerboas stay out of the sun by living in tunnels. In freezing cold, the Arctic fox protects itself with soft, thick fur while the walrus stays warm because of its thick fat called blubber.
