The Sumatran rhinoceros subspecies, D.s. harrissoni, once widespread on Borneo, is now confirmed to exist only in the northeast state of Sabah (Malaysia) and is possibly extinct from former habitat in the Bornean states of Sarawak (Malaysia) and in Kalimantan (Indonesia).
A 2005 survey in the interior of Sabah found evidence of at least 13 rhinos, and scattered individuals are found in other parts of the state.
Physical Description
The Sumatran, or hairy, rhino is the smallest of the living rhinoceroses and the only Asian rhino species with two horns. Another characteristic are the wrinkles around its eyes. The front horn is generally under 10 inches long, while the posterior horn is usually quite small and often no more than a hump. Calves are born with a dense covering of hair which turns reddish brown in young adults and becomes sparse, bristly and almost black in older animals.
Size
The body length ranges from 6 - 9 feet and usually about 3 feet in height. Body weight has been estimated at 0.5 - 1 ton.
Color
The skin of adults is reddish-brown.
