Fibrous proteins are only found in animals.
Fibrous proteins form 'rod' or 'wire' -like shapes and are usually inert structural or storage proteins. They are generally water-insoluble. Fibrous proteins are usually used to construct connective tissues, tendons, bone matrix and muscle fiber.
Fingernails and claws are made up of the common fibrous proteins, Keratin.
