Keratin is a fibrous, structural protein found in birds, reptiles, mammals and amphibians. Hair, horns, nails, claws, beaks, turtle shells, feathers and hoofs are all made from different types of keratins. It is a useful protein because it is easily made by the body and is quite versatile. It can form the soft, insulating coat of a sheep and also the tough, hard horn of a rhinoceros. Human fingernails are also made of a type of keratin and serve as a layer of protection to the sensitive nerve endings at the tips of our fingers.
