animals can have lots of skin coverings. Like fish have scales, and dogs have fur.
If you study a human's skin on there head you can see tiny little bits of hair. hair is another kind of covering. If you closely look on a horse's head you can see hair starting at there head and ending at the end of there neck. some people think you should only call that kind of mane fur or hair. But the proper
use is mane. a horse and a lion both have a mane.
