There are 5 types of rhinoceros in the world including the White rhinoceros, the Black rhinoceros, the Indian rhinoceros, the Javan rhinoceros, and the Sumatran rhinoceros. There are only 3 White rhinoceros in the world protected by being in captivity. There are 44 Javan rhinoceros. There are 2,850 Indian rhinoceros. The remaining 18,000 in the world are White and Black rhinoceros.
Indian rhinoceros was created in 1758.
Rhinos do not have tusks. Their teeth are flattened so they can eat grass. They do, however, have a large horn on top of their nose for defense.
The Indian Rhinoceros is also often called the Greater One-horned Rhinoceros or the Asian One-horned Rhinoceros, because it has one horn.
A tusk really is a tooth. Therefore, there are elephant, narwhal and walrus tusks. Tusks sometimes are called horns. But horns aren't necessarily teeth. An example is the rhinoceros, whose horn isn't a tooth at all.
