1. There are 5 species of rhino in the world

These include two African rhino species - black and white rhinos. The remaining three are Asian rhino species, which include greater one–horned, Sumatran and Javan rhinos.

The Sumatran, Javan and Black rhinos are listed as ‘critically endangered’ by the IUCN - there are thought to be fewer than 70 Javan rhinos and between 34-47 Sumatran rhinos left, which makes them truly under threat of extinction in the wild. There are an estimated 6,487 black rhinos across Africa.

The white rhino is classified as 'near threatened’ with 16,803 individuals, whereas the greater one-horned rhino is currently vulnerable with 4,014 individuals in the wild.
