Panorama of a Safari Park field exhibit with giraffes, water buffalo, and rhinos





Rhinos may look tough, but their skin is actually quite sensitive. They can sunburn, and biting insects "bug" them. That's why they like to wallow in mud—it puts a layer between their skin and the sun, and insects. Greater one-horned rhinos look as if they are wearing armor, but they are actually covered with a layer of skin that has many folds. Formerly called Indian rhinos, they are native to humid, swampy areas of Northeast India and Nepal. Greater one-horned rhinos are listed as Vulnerable on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species.

Did you know? Finding a way to mimic the way rhino horn forms and repairs itself could lead to better impact-resistant bumpers for cars.
