More Information

Physical Description

Allen's swamp monkeys are strong primates covered in grayish-green fur. Males are much larger than females. These tree-dwellers forage on the ground and browse for fish and insects in shallow water. Like most other guenon monkeys, they are quite intelligent and curious; they are often seen manipulating objects.

Interesting Fact 1

Allen's swamp monkeys communicate through gestures and calls. Males emit a deep, throaty croak while younger individuals produce a chipring sound, often to indicate alarm.

Interesting Fact 2

Webbed fingers and toes enable them to swim very well. They will often dive into water to elude predators, such as eagles and snakes.

Interesting Fact 3

Lincoln Park Zoo scientists study their memory and problem-solving by presenting them with complex tasks.
