The name ‘Colobus’ comes from a Greek word meaning ‘mutilate one’ because unlike other monkeys, black-and-white Colobus do not have any thumbs. This may be an adaptation for quick movements through the trees.

Eating mainly leaves and vegetation, Colobus monkeys have specialised stomachs that are divided into two regions; the upper stomach digests the leaves with the help of bacteria, while the lower uses acid to complete the process. Stomach contents can make up to a quarter of an adult Colobus’s weight.

The National Zoo & Aquarium is home to 7 Colobus Monkeys and is part of a regional breeding program.
