Sumatran Orang-utan

Sumatran Orang-utan:  The Sumatran orangutan (Pongo abelii) is one of the two species of orangutans. Found only on the island of Sumatra, in Indonesia, it is rarer than the Bornean orangutan. The Sumatran orangutan grows to about 1.4 metres (4.6 ft) tall and 90 kilograms (200 lb) in males. Females are smaller, averaging 90 centimetres (3.0 ft) and 45 kilograms (99 lb). Compared to the Bornean species, Sumatran orangutans are thinner and have longer faces; their hair is longer with a paler red color. Compared with the Bornean orangutan, the Sumatran orangutan tends to be more frugivorous and especially insectivorous.

Wild Sumatran orangutans in the Suaq Balimbing swamp have been observed using tools. An orangutan will break off a tree branch that is about a foot long, snap off the twigs and fray one end. It then will use the stick to dig in tree holes for termites. They will also use the stick to poke a bee's nest wall, move it around and catch the honey. In addition, orangutans use tools to eat fruit. When the fruit of the Neesia tree ripens, its hard, ridged husk softens until it falls open. Inside are seeds that the orangutans enjoy eating, but they are surrounded by fiberglass-like hairs that are painful if eaten.
