Rhinos of Java
Javan rhinos used to be the most widespread Asian rhinoceroses on the planet but have been hunted to near extinction. The best estimates put the remaining numbers between 46 and 66 individuals. The few Javan rhinos left in the wild live in two small and separate national parks — none live in zoos. The animals are valued by poachers for their horns which can fetch as much as $30,000 per kilogram on the black market. The future does not look good for this rhino — those that aren't killed by poachers can look forward to a uncertain future of disease and health problems caused by inbreeding. Rhinos don't do well in zoos in general, and the Javans have fared even worse; the last captive died in an Australian zoo in 1907.
