They are primates, and that they have reddish-brown fur. I searched for information in the Owl , Ranger Rick , and National Geographic World magazines. I also used Birute Galdikas's Among the Orangutans book, which gave me information on her work with orangutans. Description of Plant or Animal Orangutans have shiny, red hair. They have powerful arms, which are eight feet long.
Orangutans have strong teeth and jaws.
Their legs are smaller and weaker than their arms. The orangutan's legs are five feet long. Orangutans are 200 pounds, and have very heavy bodies. Orangutans are the largest arboreal mammal. Arboreal means living in trees.
