Here are some fascinating swamp monkey facts that both children and adults can use to learn more about this species.

Swamp monkeys are also called Allen’s swamp monkey (Allenopithecus nigroviridis) and are  discovered in the swamp forests of the Congo basin and Dzanga-Sangha Forest Reserve in the CAR (Central African Republic).

This species of primates is named after the first President of the American Ornithologists’ Union Joel Ashap Allen.

Swamp monkeys are arboreal, which means that they live in trees; these primates are also diurnal. This species is extremely social and prefers living in groups of at least 40 monkeys.

Swamp monkeys are closely related to the Guenons, but they are not true Guenons, because Guenons evolved from a group of monkeys about ten million years ago.

Supposedly six million years ago another evolution occurred from which modern Cercopithecus monkeys evolved, and a large number of primatologists assume that the swamp monkeys are the intermediate link between the Gueonons and other groups of monkeys which is very evident from the physical traits of the monkeys but the extraordinary component is their fingers and tail.

Allen’s swamp monkeys forage on the ground, trees, and water and their diet consists of fruits, leaves, worms, insects, and fishes which are widely available in their habitat.
