  • I think its Ivory
  • Hard skin.
  • It is hair.It’s made of keratin—that’s the stuff your hair and nails are made of. The horn is a pretty distinctive feature—the name “rhinoceros” is actually made of two Greek words meaning “nose” and “horn”. Tragically, rhinos are often killed for their horns. The once-large rhinoceros family has dwindled to just a few living species almost all of which are threatened with extinction.
  • Beleive it or not...Rhino Hair.
  • 1) "The most obvious distinguishing characteristic of the rhinos is a large horn above the nose. Rhinoceros horns, unlike those of other horned mammals, consist of keratin only and lacks a bony core, such as bovine horns. Rhinoceros horns are used in traditional Asian medicine, and for dagger handles in Yemen and Oman. One repeated fallacy is that rhinoceros horn in powdered form is used as an aphrodisiac in Traditional Chinese Medicine. It is, in fact, prescribed for fevers and convulsions. Discussions with TCM practitioners to reduce its use have met with mixed results since some TCM doctors see rhinoceros horn as a life-saving medicine of better quality than substitutes. China has signed the CITES treaty however. To prevent poaching, in certain areas rhinos have been tranquillized and their horns removed."

They are rivaled as biological materials in toughness only by chitin. There are various types of keratins within a single animal." "Keratins are the main constituent of structures that grow from the skin: the α-keratins in the hair (including wool), horns, nails, claws and hooves of mammals the harder β-keratins in the scales and claws of reptiles, their shells (chelonians, such as tortoise, turtle, terrapin), and in the feathers, beaks, and claws of birds."

  • The simple answer is that rhino horns are made of the same protein (keratin) that makes hair. It was previously thought that rhino horns were made of hair but it is now known that they merely share the same base substance.
