Siamang

**Siamang**
The Siamang looks like a monkey but it is actually an ape! Monkeys have tails while apes don't. Siamangs are the largest member of the gibbon family. Siamangs are the "kings of swing" in the forest. They move through the branches with a hand over hand locomotion called brachiation. You can try to swing like a siamang on our brachiation bars by the exhibit. The siamang is better equipped to do this than we are with their long fingers that act like a hook and their smaller opposable thumb and also an opposable big toe. So they can grab and pick things up with their hands and feet. The siamang also has a throat sac that inflates like a balloon when it vocalizes. The male and female each sing a different part of this volcalization duet that can be heard for miles through the forest. In fact, they are considered the loudest land mammals in the world. Siamangs are native to the forests of Malaysia, Thailand, and Sumatra.
