A rhinoceros, often abbreviated to rhino, is one of any five extant species of odd-toed ungulates in the family Rhinocerotidae, as well as any of the numerous extinct species. Rhino are well known for their large keratinous horns, which they are heavily poached for for human use, as well as their general large size, thick armor-like skin, and heavy weight.
Facial horn count differs by species; both African and Sumatran rhino have two, while Indian and Javan have one.
