The orangutans (also spelled orang-utan , orangutang , or orang-utang ) [6] are three extant species of great apes native to Indonesia and Malaysia . Orangutans are currently only found in the rainforests of Borneo and Sumatra . Classified in the genus Pongo , orangutans were originally considered to be one species. From 1996, they were divided into two species: the Bornean orangutan ( P. pygmaeus , with three subspecies) and the Sumatran orangutan ( P. abelii ). In November 2017 it was reported that a third species had been identified, the Tapanuli orangutan ( P. tapanuliensis ). [7] [8] [9] Genomic comparisons show that the Tapanuli orangutan separated from the Sumatran orangutan about 3.4 million years ago. The Tapanuli orangutan separated from the Bornean orangutan much later, about 670,000 years ago. The orangutans are the only surviving species of the subfamily Ponginae , which also included several other species, such

with only one known population in the wild, and no individuals in captivity. It is possibly the rarest large 2 The Javan rhinoceros ( Rhinoceros sondaicus ), also known as the Sunda rhinoceros or lesser one-horned rhinoceros , is a very rare member of the family Rhinocerotidae and one of five extant rhinoceroses . It belongs to the same genus as the Indian rhinoceros , and has similar mosaicked, armour-like skin, but at 3.1–3.2 m (10–10 ft) in length and 1.4–1.7 m (4.6–5.6 ft) in height, it is smaller (closer in size to the black rhinoceros of the genus Diceros ). Its horn is usually shorter than 25 cm (9.8 in), and is smaller than those of the other rhino species. Only adult males have horns; females lack them altogether. Once the most widespread of Asian rhinoceroses, the Javan rhinoceros ranged from the islands of Java and Sumatra , throughout Southeast Asia, and into India and China . The species is critically endangered , with only o
