Asian elephants generally have significantly more hair on the head and back than their African relatives. The very fact that they have hair at all, is surprising. After all, a thick fur is well known for keeping you warm, which seems rather impractical in the tropical heat. Their hair is, however, very fine. When a fresh gust of wind blows through the thin fuzz, it cools them down. Elephants even have hairs on their tusks. Just like cat whiskers, they serve to sense the environment.
