Rhinoceroses are some of the largest remaining megafauna: all weigh at least one tonne in adulthood. (It can also refer to a member of any of the extinct species of the superfamily Rhinocerotoidea.) Two of the extant species are native to Africa, and three to South and Southeast Asia. A rhinoceros ( / r aɪ ˈ n ɒ s ər ə s/, from Greek rhinokerōs 'nose-horned', from rhis 'nose', and keras 'horn'), commonly abbreviated to rhino, is a member of any of the five extant species (or numerous extinct species) of odd-toed ungulates in the family Rhinocerotidae.
