The Sumatran or hairy rhino (Dicerorhinus sumatrensis) is the smallest of the five rhino species. Official estimates suggest that there are only 34-47 individuals remain in, according to figures published in 2025. They can be found in dense tropical forests in Sumatra and in Kalimantan, on the island of Borneo, both in Indonesia. 

Sumatran rhinos are the only rhinos that are have hair all over their bodies. Their hair is generally short and bristly in the wild, but it can grow to a shaggy coat in captivity since it is not rubbed off on vegetation. Just like the black rhino, they are browsers, using a prehensile upper lip to grasp leaves from a variety of plants. They are known to eat up to 60kg of food a day.

Fun fact: The Sumatran rhino is the oldest living land mammal and is the closest living relative to the famous woolly rhinoceros that lived in the frigid lands of Europe and Asia during past ice ages.
