- Orangutan Species
Researchers believe that many species of orangutans once existed. Unfortunately only two of them have been able to successfully continue to evolve and last until now.
- Bornean Orangutan
One of only two species of orangutans, the Bornean Orangutan is the largest of the two. The males are larger than the females which is common among the great apes.
- Sumatran Orangutan
The smaller of the two species, the Sumatran orangutan is very strong. A full grown male is approximately 200 pounds and 4 and a half feet tall.
