Orangutans

Orangutans are the only exclusively Asian genus of extant great ape. The largest living arboreal animals, they have longer arms than the other, more terrestrial, great apes. They are among the most intelligent primates and use a variety of sophisticated tools, also making sleeping nests each night from branches and foliage. Their hair is typically reddish-brown, instead of the brown or black hair typical of other great apes.

Orangutans are one of the three species of apes featured in the Planet of the Apes film series. Orangutans are the leader of ape society. They also represent the religious body of their culture. They are scientifically minded as well, but are otherwise governed by what they believe to be "rational thought" and a system of logic; so long as that system of logic does not contradict accepted ape views as laid out scripture or accepted scientific proof. The authoritative body of Central City is led by a council of orangutans, the most esteemed of which is Councillor Zaius, who often finds himself mediating affairs that arise between chimpanzees, gorillas and the humans.
