small heavily built primate of the Congo River basin. It is dark olive in colour, with orange or whitish underside. The head and body length is about 450 mm (18 inches), and there is a somewhat longer tail; females weigh 3.7 kg (8 pounds) on average, males 6 kg. They live in groups of about 40, mainly in swamp forest, where they spend as much time on the ground as they do in the trees foraging for fruit and invertebrates. Swamp monkeys can swim and will jump into the water to escape predators.
