The African elephant is the world’s largest land mammal, and it’s also nearly hairless. This is because of an adaptation to the hot, dry climate in which it lives.

Why do elephants don’t have fur?
The African elephant is the world’s largest land mammal, and it’s also nearly hairless. This is because of an adaptation to the hot, dry climate in which it lives.
