Rhinoceroses are large herbivorous mammals belonging to the family Rhinocerotidae. There are five species of rhinoceroses: the white rhinoceros (Ceratotherium simum), the black rhinoceros (Diceros bicornis), the Indian rhinoceros (Rhinoceros unicornis), the Sumatran rhinoceros (Dicerorhinus sumatrensis), and the Javan rhinoceros (Rhinoceros sondaicus). They are characterized by their massive bodies, thick skin, and one or two horns made of keratin, the same substance that makes up nails and hair.

Rhinoceroses are primarily found in Africa and Asia. The African species (white and black) live in savannas and semi-arid regions, while the Asian species inhabit tropical forests and grasslands. Rhinoceroses have an herbivorous diet, feeding on grass, leaves, branches, and shoots, depending on the species and habitat. Despite their imposing size, rhinoceroses are relatively shy and solitary animals, except for mothers with calves.

Unfortunately, all species of rhinoceroses are endangered, mainly due to poaching and habitat loss. Their horns are highly valued on the black market, especially in traditional Asian medicine, where they are wrongly believed to have healing properties. Rhinoceros conservation involves international efforts, including habitat protection, anti-poaching patrols, and captive breeding programs. Global awareness and conservation initiatives are crucial to ensuring the survival of these magnificent creatures in the future.
