Rhino horn riddle

Many people believe that animal horns are made of bone and the truth is most are. Then there are animals like the rhino who have a more unique horn. Scientists at Ohio University have recently discovered that the rhino horn isn't bone or tooth it is made up of hair or keratin. the center of a Rhino horn is filled with calcium and melanin deposits. while the hair in the out side may be soft it has a strong core to protect the rhinos horn. like a wooden pencil has a weaker wood outside and a stronger lead inside, and it allows the pencil to be sharpened with out breaking. the rhino horn is built the same way while out side is soft the core is strong and allows it to be used for digging and fighting without damage.

The impact this will have on the world is that its show the different variations in animals horns. this also is a bad situation for the rhinos to have such special horn because poachers have a better reason to hunt and kill them for their horns. rhino populations are decreasing because of poachers killing them for their horns.

I thought this articles was interesting. i always figured that a rhinos horn was a bone or tooth growing out of their face. I found it sad that rhinos are endangered because they have such rare horns. i say save the rhinos!
