Chimpanzees
Chimpanzees are great apes that live in the tropical rain forests of Africa from Sudan and Tanzania in the East to Senegal and Angola in the West. Democratic Republic of the Congo has the largest population, although chimpanzees have become extinct in some areas. They grow to reach heights of three to five feet, and weigh up to 120 to 200 pounds. They are predominantly black, sometimes with gray on their back after 20 years of age.
Orangutans
Orangutans are found in the tropical rain forests of only two islands in the world: Sumatra (in Indonesia) and Borneo (in Malaysia and Indonesia).
They are the largest arboreal (tree dwelling) animal in the world, reaching heights of four to five feet and weights of 125 to 235 pounds or more. Orangutans are reddish-brown in color and some males grow white or yellow beards. Also characteristic are their bare faces with round eyes and small ears; their long, shaggy hair; long arms; and curled fingers and feet.
