Watching golden lion tamarins:
You are viewing an enclosure in the Zoo's Small Mammal House where a pair of golden lion tamarins (GLTs) lives. Tune in Wednesdays at 11 a.m. Eastern Time to see the GLTs get an enrichment item. You may see other animals that live here too, such as a pair of saki monkeys, sloths, or an acouchi. There are only about 1,500 GLTs in the wild. For decades, Zoo scientists have collaborated with conservation organizations to help save from extinction these endangered monkeys.

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 organgutans can sometimes be seen overhead as they travel along the O Line between the Great Ape House and Think Tank. The time visitors are mostly likely to see these apes on the O Line is between 11 and 11:30 a.m.
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
