"Rhinos have lived on earth for over 50 million years but whether they survive even 50 more years is open to speculation. Only 5 species of rhino exist today when once there were over 100 species. All 5 species- the white, black, greater one-horned, Sumatran and Javan are endangered. Only the white rhino with a population of 4,600 seems to be somewhat safe from extinction. In 1960, 60,000 black rhinos roamed Africa. Today only 2,500 remain in isolated populations. On the Asian continent, the greater one-horned population remains at 2,000. The Sumatran species numbers around 200 and the Javan species has fewer than 60 animals"--AAZK National Chapter
