Siberian orangutan

The **Siberian orangutan** (*Pongo lasiotus*), also known as the **Russian orangutan**, the **polar orangutan**, and the **Arctic orangutan**, is a species of orangutan that originally did not exist, but has since been created by SciiFii and introduced throughout the temperate, boreal, and alpine forests, wetlands, and open woodlands across Russia, Ukraine, Kazakhstan, Kyrgyzstan, Mongolia, and China to help boost biodiversity. The Siberian orangutan is one of the largest living species of orangutan, with the average weight of a male being around 200 kilograms (440 lbs), however, the males can grow slightly larger. The Siberian orangutan has a distinctive body shape with very long arms that may reach up to 1.5 metres in length. It has grey skin, a coarse, shaggy, brown coat, thickened blubber underneath its skin and prehensile, grasping hands and feet. The Siberian orangutan, unlike other species of orangutans, is adapted to freezing environments thanks to its thicker fur and blubber to insulate its body. Its coat covers its face unlike other orangutan species, and the Siberian orangutans also have distinctive facial including a beard and mustache. It also has large, fatty cheek pads known as flanges as well as a pendulous throat sac. Siberian orangutans are highly sexually dimorphic and have several features that differ between males and females. Males have much larger cheek pads, or flanges, that are composed of muscle and large amounts of fat. In females, the flanges are mostly composed of muscle. Males have relatively larger canines and premolars. Males have a more pronounced beard and mustache. The throat sac in males is also considerably larger. There are two body types for sexually mature males: smaller or larger. Larger males are more dominant but smaller males still breed successfully. There is little sexual dimorphism at birth. The Siberian orangutan diet is composed of over 400 types of food, including wild figs, durians, leaves, seeds, bird eggs, flowers, sap, vines, honey, fungi, spider webs, insects, and, to a lesser extent, bark. They have also been known to consume the inner shoots of plants and vines. They will also occasionally eat nutrient rich soil. They get the necessary quantities of water from both fruit and from tree holes. The Siberian orangutan exhibits nest-building behavior. Nests are built for use at night or during the day. Young orangutans learn by observing their mother's nest-building behaviour. This skill is practiced by juvenile orangutans. Nests may be elaborate and involve a foundation and mattress made by intertwining leaves and branches and adding broken leafy branches. Additional features such as shade, waterproof roof, "pillow", and "blanket", all of which are made from branches, twigs and leaves, may also be added. Nest-building in primates is considered as an example of tool use and not animal architecture. Siberian orangutan are about as solitary as their Bornean relatives. Two or three orangutans with overlapping territories may interact, but only for short periods of time. Although orangutans are not territorial, adult males will display threatening behaviors upon meeting other males, and only socialize with females to mate. Males are considered the most solitary of the orangutans. The Siberian orangutan has a lifespan of 35–45 years in the wild; in captivity it can live to be about 60. The conservation status of the Siberian orangutan is **Near Threatened** due to some habitat loss and historic poaching, however, thanks to the conservationists, the Siberian orangutans are a protected species and are making a comeback.
