Do any species of rhino have ivory horns?

they are made of keratin....which IS what makes up hair...so the people contradicting each other are wrong...they are actually made of BOTH keratin AND hair since one makes up the other. However they are NOT ivory.

Do any species of rhino have ivory horns?
The horns of a rhino are made of fibrous keratin, the same substance that forms our hair and nails. So, no ivory there.





Ivory is just another name for dentine, the substance that makes up most of our teeth (usually teeth have an outer and harder layer of enamel, a middle dentine layer, and an inner cavity filled with the pulp). The teeth of rhinos have both enamel and dentine (ivory), and they're quite large, so I guess somebody could use them and call them "horns" by mistake.


Horns are never made of ivory; they're formed by bone and/or keratinous sheaths. Ivory only occurs in teeth (including elephant tusks, which are their incisors).
Reply:The people who says that they are ivory are wrong they are made of keratin, the same stuff as your fingernails.
Reply:No. Rhino horns consist solely of hair.
Reply:airbob61's answer is true. the horn of rhino is not true horn. it is true that most of animal horn are made up from keratin and other protein but for rhino it only made from keratin and built from compacted hair.
Reply:Rhinos have horns where Elephants have tusk, which are ivory. There are five species of rhinoceros that I know of, they all have horns

Rhino horns differ from true horns because these horns have no core or sheath. They are made up of multitude of epidermal cells and bundles of dermal papillae, extensions of the dermis. Cells from each papilla form a horny fiber similar to thick hair. These fibers, which are held together by the mass of epidermal cells, are not true hairs. True hair grows from follicles that extend into the dermis, whereas rhino horns grow from dermal papillae which extend up into the horn. The rhino horn is situated over the nasal bones. In species that have two horns, the second horn lies over the frontal bones. Rhino horns commonly curve posteriorly.
Reply:Pretty much all of these answers are true. But to answer your question, all rhinos horns are ivory.
