Rhinoceroses are large, heavy-hoofed animals. Their horns are not made of bone, but out of a material similar to that of our finger nails and hair.
The rhinoceros is a huge animal with fearsome horns. Nevertheless, it is a passionate herbivore. With the horns, it defends itself against hyenas, fights against rivals or digs up tasty roots. Although the skin of the rhino looks very thick, it is actually very thin and delicate, just like the skin of elephants. To cool off and avoid sunburn, it wallows in the mud. You often see small birds on rhinos, hopping around and pecking. They free the rhinos of annoying parasites.
The horn of a rhinoceros can grow to up to 1.5 metres in length.
