As of 2014, the rhinoceros is not extinct, but it is considered to be at heightened endangerment of becoming extinct. There are less than an 30,000 rhinos left in the world. Five different species of rhinoceros exist, with each one having different populations of rhinos remaining.
Of the five different species left, the white rhino has the most living members, with an estimated population of over 20,000, as of 2014. The black rhino, however, only has about a quarter of the white rhino population.
The Sumatran and Javan species face the largest risk to extinction, with no more than 100 Sumatran rhinos and less than 50 Javan rhinos remaining, according to 2014 estimates. The fifth species, the greater one-horned rhino, has about 3,300 left. Poaching is a chief reason for the low population, along with a decreasing total habitat area.
