Kalimantan and Sumatra are the only places on Earth where tigers, rhinos, orangutans and elephants live together.
These great apes share 97 per cent of their DNA with humans. Their name comes from orang – meaning ‘person’ – and hutan – meaning ‘forest’. When stretched out, their arms can be 2 metres from fingertip to fingertip.
The sunda clouded leopard
Only found on the islands of Borneo and Sumatra, the coat of this elusive cat is dotted with large, dark-edged ovals, said to be shaped like clouds. Its canine teeth are over 5cm long, and its tail – which gives it balance – can be as long as its body.
This bizarre-looking little critter is a tree-dwelling nocturnal primate with very large eyes, a long tufted tail and very long hindlimbs. The tiny creature grows to a maximum of 15cm and is known for its extraordinary leaping ability.
Borneo pygmy elephant
This elephant looks most like Disney’s Dumbo, and only about 1,500 of these long-tailed pachyderms are thought to be alive in the forests of Borneo. While the largest African elephant ever found was 3.96 m high, the Borneo pygmy ‘only’ reaches 2.7 m.
