Watching orangutans: The Zoo is home to six orangutans, four females and two males. They have access to the Great Ape House and Think Tank, a place to think about thinking. Native to tropical rainforests, orangutans are Asia's largest primates and the world's largest tree-dwelling animals.

Primates at the Zoo


The Zoo is home to many primates. Orangutans and western lowland gorillas can be found at the Great Ape House. Smaller primates, including golden lion tamarins, Geoffroy's marmosets, and howler monkeys, can be found in the Small Mammal House. Look for gibbons at Gibbon Ridge and lemurs at Lemur Island. Find out where primates can be seen at the Zoo.

On mild days, the orangutans can sometimes be seen overhead as they travel along the O Line between the Great Ape House and Think Tank.

About Primates

There are 376 species of primates in the world—from humans and apes to monkeys and prosimians ("premonkeys").

The smallest primate is the pygmy mouse lemur, which can fit in the palm of your hand. The largest—the gorilla—can weigh more than 400 pounds. Most primates live in warm climates, and most depend on forests for their survival. More Primate Facts
