This was the first footage showing the elusive rhino's natural behavior in the wild. In April 2007, it was announced that a camera trap in Sabah had captured footage of a Bornean rhinoceros eating and investigating the equipment.
The Bornean subspecies may also be more of a browser than most Asian rhinos. They mark their territory with scrapings, bent saplings and scent marks. These animals are very good swimmers and can maneuver well on steep slopes. Rare minerals are gained from salt licks. The animals eat around 50 kg (110 lb) of plant matter per day. It usually feeds at dusk and bathes in mud during the day. The Bornean rhinoceros, like most rhinos, is a solitary animal that lives in dense rainforest and swamps. However, being a species which existed before the end of the Pleistocene, it is likely that this was not the habitat in which they evolved. Today, the Bornean rhinoceros, like the Sumatran rhino, lives in hot, humid closed canopy rainforest. Reports of animals surviving in Sarawak are unconfirmed. A recently captured specimen and video evidence from camera traps have confirmed their continued presence in East Kalimantan, now believed to hold the entire wild population. However, this population is now believed to be extinct. Previously, the entire known wild population lived in Sabah, mostly in the Tabin Wildlife Reserve. The difference from the Western Sumatran rhinoceros is mainly genetic.īornean rhinos used to range all over Borneo, but their range has been severely reduced. Like the Black rhinoceros it has a prehensile lip. The rhinoceros has fringed ears and wrinkles around its eyes. The head size is also relatively smaller.

The Bornean rhinoceros has the darkest skin of the Sumatran rhinos, and the fur of calves is much denser, but it becomes darker and more sparse as the animal matures. The Bornean rhinoceros is markedly smaller than the other two subspecies, making it the smallest of the extant rhinos. Physical descriptions Preserved Bornean rhinoceros The Bornean subspecies Dicerorhinus sumatrensis harrissoni, was named in honour of the British polymath Tom Harrisson, who worked extensively with Bornean zoology and anthropology in the 1960s. The International Union for Conservation of Nature (IUCN) classifies the subspecies as critically endangered. However, in March 2016, a young female rhino was captured in East Kalimantan (in the Indonesian portion of Borneo), providing evidence of their continued existence. In April 2015, the Malaysian government declared the Bornean rhinoceros to be extinct in the wild in the Malaysian portion of Borneo.
The subspecies may be functionally extinct, with only one individual, a female named Pahu, surviving in captivity, and held in the state of Sabah. The Bornean rhinoceros ( Dicerorhinus sumatrensis harrissoni), also known as the eastern Sumatran rhinoceros or eastern hairy rhinoceros, is one of three subspecies of Sumatran rhinoceros.
