Rhinoceros or rhino species are among the largest land mammals to exist weighing in at least a tonne. There are five extant species, three of which are found in Southern Asia and two in Africa. Rhinos are often classified by their huge mass, leathery armour and keratin horn.
All rhino species are herbivorous; they generally graze on grass or eat leafy bushes and lack front teeth. The Indian and the Javan rhinoceros both only have one horn while the Black, White and Sumatran rhinoceros sport two large horns.
Rhino’s are critically endangered. The white rhino has two subspecies; the Northern and the Southern white rhinoceros. While the Southern white rhino has a wild population over 20,000 the Northern subspecies is almost completely extinct, with only three animals left in captivity.
Rhino’s are at risk of extinction due to habitat loss and poaching. In Vietnam the illegal rhinoceros horn trade circulates millions of dollars each year. People use the horn for medicinal purposes even though there is no scientific proof of its benefits. To get the horn from a rhino, the animal must be killed first, leading to the huge decline in the wild population of all species.
