The Tapanuli orangutan (Pongo tapanuliensis) is a Critically Endangered species on the IUCN Red List with just 800 individuals. Tapanuli is a hilly region in north Sumatra island.
The Tapanuli orangutan looks more like Sumatran orangutans than their Bornean cousins. The males have a mustache and large cheek pads, which are covered in brown hair. The Tapanuli orangutans have small heads, frizzy hair, and wider and flatter faces.
Females also have facial hair like male beards. Tapanuli orangutan from the family Hominidae has larger upper canines, shallower face depth, and other such features that separate them from the other two orangutans.
The Tapanuli orangutans are considered the rarest of great apes. There are about 800 individuals only in a 1000 square kilometer area. The word orangutan means forest man in Malay.
They come in colors like gray, brown, black, red, and orange. These wild animals were named as a distinct species from their Bornean cousins in 2017.
The Tapanuli orangutans are the only great species of orangutan/apes found outside of Africa. Here are some interesting facts about the critically endangered species of orangutan. Afterward, do check the other articles on siamangs and Sumatran orangutans.

Where does a Tapanuli orangutan live?
The Tapanuli orangutan habitat can be found exclusively near Lake Toho in south Tapanuli on the island of Sumatra in Indonesia and Sumatra's Batang Toru Forest. This is in the northwestern part of the Sumatran islands.
The Sumatran orangutan species is found between 1000-43000 ft (304-1310 m) above sea level. These wild animals reside in a 1000 sq m region in the Batang Toru Forest.
What is a Tapanuli orangutan's habitat?
Tapanuli orangutans are found in the dense tropical and subtropical broadleaf forest of the south Tapanuli region on the Sumatra island in Indonesia. The Sumatran orangutan (Pongo abelii) species is arboreal as they spend most of their time living on a tree.
These orangutans are also thought to be arboreal as scientists have rarely seen them on the ground. These wild animals build a nest for sleeping in the high trees under a canopy of folded branches in their habitat in Sumatra.

The Tapanuli orangutan comes together only for mating. Other than that these great apes live a lonely life.
Males have a long call for mating, which is loud and booming and can be heard from a distance of 6.6 mi (1 km) through the trees. These calls attract females.
There is not much known about their mating rituals apart from this. The female will give birth to a single infant after a gestation period of nine months.
The baby orangutans will live with their mothers for seven years and are clingy babies.
During this period the mother orangutan will teach the baby how to survive in the forests and pass vital information like which plant to eat, how to build a nest, and the utilization of rudimentary tools in daily life. All three apes of Sumatra island are considered slow-maturing animals in the world.
These orangutans cannot breed till the age of 12-15 years. The female orangutan will have a maximum of three offspring in her lifetime, which is one of the reasons why the population of these apes has always been low.
What is their conservation status?
The Tapanuli orangutan is Critically Endangered in terms of its conservation status and is facing the threat of extinction due to humans. The main reason for the threat of extinction is habitat fragmentation, illegal hunting, conflict with humans, and illegal wildlife trade.
The habitat loss is due to the loss of forest region to small-scale farming, mining, and a hydroelectricity dam, the Batang Toru hydropower project in the area around Lake Toho which is the only area where these orangutans are found.
If necessary steps are not taken, 85% of the population will undergo extinction in three generations.
This means that there is a threat of them going extinct soon. There are fewer than 800 individuals found in the world right now and the population is decreasing.
