There are five species of rhino: the black rhino and white rhino in Africa, the Asian (or Sumatran) rhino, Indian rhino and Javan rhino.
All rhinos are very endangered. The Asian, Javan and Northern white rhinos are critically endangered on the CITES IUCN (International Union for Conservation of Nature and Natural Resources) Red List.
Many regions have developed rhino sanctuaries that are closely guarded to protect them from poachers. This has worked for some species like the Southern white rhino and black rhino in Africa and the Indian rhino. All are increasing in numbers from being critically endangered.
