Answer:
An important distinguishing character of mammals is their hair. They also possess many other derivatives of the epidermis, including nails, claws, hooves, quills, and horns. All mammalian hard keratin, as well as the soft keratin of the stratum carenum, is of the alpha type.Bony dermal plates are found in the armadillo.
