FUN FACT: Rhinoceros horns are made out of hair! Trent was right that hair is made out of the same stuff that fingernails are made out of.  It's called keratin. 

I found a website that explained it like this: "The horns of most animals have a bony core covered by a thin sheath of keratin, the same substance as hair and nails. Rhino horns are unique, however, because they are composed entirely of keratin."
