FreeA nail is a horn-like envelope covering the dorsal aspect of the terminal phalanges of fingers and toes in humans, most non human primates, and a few other mammals.
Nails are similar to claws in other animals. Fingernails and toenails are made of a tough protective protein called keratin. This protein is also found in the hooves and horns of different animals.
