Rhino Facts and the Secret of Its Horn — Nature Observation Picture Book
What makes a rhino so amazing?
With its big horn and thick skin, the rhino is a plant-eater that looks like it's wearing armor. And its horn holds an unexpected secret.

Nature and science facts about the rhino
A rhino's big horn is not bone — it's made of keratin, the same stuff as our hair and nails, so it can grow and wear down. Its thick, tough skin is like armor. The rhino is a plant-eater that feeds on grass and leaves, and although its eyesight isn't very sharp, it has an excellent sense of smell and hearing. On hot days it takes mud baths to protect its skin, and sadly, poaching for its horn has left it endangered, so it needs our protection.
