OVERVIEW
Sumatran rhinos are the smallest of all living rhinos, and the only Asian rhinos with two horns. They are covered with long hair and are more closely related to the extinct wooly rhinos than any of the other rhino species alive today. Sumatran rhinos compete with Javan rhinos for the unenviable title of most endangered rhino species. Indeed, whilst surviving in greater numbers than the Javan rhino, Sumatran rhinos are at a greater risk for poaching. In addition, there is no indication that the population is stable, with only two captive females reproducing in the past fifteen years.
