Derived from the Malay words for “person of the forest".
The Sumatran orangutan lives in the trees of the tropical and subtropical rainforests of Sumatra.
Adult males are typically solitary. Females create social structures to prevent being harassed by sub-adult males during the mating season, which can include bonding with other females or non-mating males.
The average lifespan for the Sumatran orangutan is from the mod 40s to the early 50s in the wild and into the late 50s in captivity.
Orangutans are large bodied animals and rely on plentiful high calorie foods with high energy content. They are vegetarians. Fruit makes up nearly all of their diet which they then supplement with leaves, shoots, seeds, buds, flowers, bark and insects. They eat soil to acquire essential minerals and sale
There are an estimated 13,000 Sumatran orangutans in the wild. They are classified as Critical Endangered by the IUCN.
Why Are They Endangered?
The relentless destruction of Sumatra’s rainforests has pushed the Sumatran orangutan to the edge of extinction. Orangutan populations are left fragmented and isolated, making them easy targets for poaching for the illegal pet trade. Conflict also ensues with local communities when the stranded and starving apes are forced to resort to raiding crops.
