Rhinoceros often colloquially abbreviated rhino, is a group
of five extant species of odd-toed ungulates in the family
rhinocerotidae. Two of these species are native to Africa
and three to southern Asia. Three of the five species—the
Javan, Sumatran and Black Rhinoceros—are critically endangered.
The greater, one-horned Indian Rhinoceros is endangered, with
fewer than 2,700 individuals remaining in the wild. The White
is registered as "vulnerable", with approximately 17,500 remaining
in the wild, as reported by the International Rhino Foundation.
