The Sumatran Orangutan

The Sumatran orangutan (scientific name pongo abelii) is a subspecies of orangutan that inhabits the tropical and subtropical broadleaf forests of Sumatra. They can grow to be 4 to 5 feet long, and they can weigh between 66 and 198 pounds. It almost exclusively lives in the trees, as males rarely and females virtually never travel on the ground. Its species as a whole reportedly has closer social ties to each other than its close relative the Bornean orangutan. This is believed to be the result of the vast amount of fruit that grows on the fig trees in its habitat, as this allows groups of it to eat together. When it comes to these community meals, males come alone and females come with their young.

The Sumatran orangutan is classified as a Critically Endangered species. It is this close to becoming extinct for two reasons. The first reason is that it is captured so that it and products made from it can be sold in the wildlife trade. Because of this, one of the World Wildlife Fund's (WWF's) efforts to save it consists of working with governments to enforce restrictions on the wildlife trade. The second reason is that much of its habitat has been destroyed by either forest fires or various agricultural developments. Because of this, another one of the WWF's efforts to save it consists of conserving the few remaining forests that make up its habitat. All of this is being done because it disperses the seeds of the fruits it eats over a huge portion of its habitat, which helps keeps several species of tree, especially ones with larger seeds, that exist there from becoming extinct.
