11 Wild Animal Species You Never Knew Were Endangered

Orangutans

There are two species of orangutans: Bornean, ones that prefer the ground over the trees, and Sumatran, which have longer facial hair and develop closer bonds with each other. A century ago, their global population was more than 230,000. Now there are between 45,000 and 69,000 Bornean (endangered status) and only 7,500 Sumatran (critically endangered status).
