Orangutans are one-of-a-kind. They’re the world’s largest tree-dwelling mammals, and the only great apes native to Asia. Found on the islands of Borneo and Sumatra, these shaggy red spend most of their lives in the treetops and eat a hundred different kinds of fruit. But they’re in trouble– the trees they depend on are being cut down to make palm oil plantations, and orangutans are now seriously endangered.

The San Diego Zoo is working to save the orangutans by providing funding to conservation projects and by contributing to scientific knowledge about these animals. By studying the DNA of the orangutans at the San Diego Zoo, scientists are able uncover the apes’ genetic past and learn how to better build conservation plans to protect them.
