Orang-utan as a characterictic of Indonesian animal

Orang-utan (Pongo pygmaeus) is the only one of the great apes that makes its home in Indonesia. Unlike other apes, they are solitary creatures, and males and females usually only associate when mating. Females will occasionally travel in groups, usually consisting of sisters or mother and daughter and various offspring.
Like humans, Orangutans have hands with opposable thumbs, and their feet also have an opposable toe. They are relatively large with the males weighing in at 170 pounds (77 kg) and reaching a length of 37 inches (95 cm). The females are smaller, usually weighing about 81 pounds (37 kg) and reaching a length of 31 pounds (78 cm). They are covered in long reddish-brown hair, except for their faces, which are black and hairless. The males develop puffy cheek pads that are attractive to the females, and they also have pouches under their throats that they use to amplify their voices.
Orangutans are very sophisticated creatures and have been known to use handfuls of leaves as napkins, wrapping them around their hands to protect them when they handle sharp or spiny objects, and use them as umbrellas to shade from the sun or protect from the weather.
