The Tapanuli orangutan (Pongo tapanuliensis) is a species of orangutan restricted to South Tapanuli in the island of Sumatra in Indonesia. [3] It is one of three known species of orangutan, alongside the Sumatran orangutan ( P. abelii ), found farther northwest on the island, and the Bornean orangutan ( P. pygmaeus ).
Ponginae / p ɒ n ˈ dʒ aɪ n iː /, also known as the Asian hominids, is a subfamily in the family Hominidae.Once a diverse lineage of Eurasian apes, the subfamily has only one extant genus, Pongo (orangutans), which contains three extant species; the Sumatran orangutan (Pongo abelii), the Tapanuli orangutan (Pongo tapanuliensis) and the Bornean orangutan (Pongo pygmaeus).
A third species, the Tapanuli orangutan (P. tapanuliensis), was identified definitively in 2017. The orangutans are the only surviving species of the subfamily Ponginae , which diverged genetically from the other hominids ( gorillas , chimpanzees , and humans ) between 19.3 and 15.7 million years ago.

The Hominidae (/ h ɒ ˈ m ɪ n ɪ d iː /), whose members are known as the great apes [note 1] or hominids (/ ˈ h ɒ m ɪ n ɪ d z /), are a taxonomic family of primates that includes eight extant species in four genera: Pongo (the Bornean, Sumatran and Tapanuli orangutan); Gorilla (the eastern and western gorilla); Pan (the chimpanzee and the bonobo); and Homo, of which only modern humans ...
Towards the end of this stage, the orangutan will stop sleeping in the mother's nest and will build its own nest nearby. From the ages of 5 to 8 years of age, the orangutan is in an adolescent stage of life. The orangutan weighs around 15–30 kilograms. The light patches on the face start to disappear, and eventually the face becomes ...
Sumatran, Tapanuli and Bornean orangutans are killed at a high rate for many reasons, the most common being the trade of meat or because farmers believe they are a threat to their crops. [16] A survey conducted by experts in the field reported that orangutans were killed for both conflict and non-conflict related reasons. [ 17 ]
[4] The Tapanuli orangutan was not described as a separate species until 2017, which led to some interbreeding between Sumatran and Tapanuli orangutans in captivity. In 2022, an orangutan named Bubbles, who was previously thought to be Sumatran, was found to be Tapanuli, making her offspring hybrids of both the Sumatran and Tapanuli species. [5]
