Lemurs live in groups of up to 30 individuals. They are diurnal and arboreal. They spend their day foraging in the trees. Their call is quite noisy and can make them sound larger than they are, if one individual calls, others will join in. To mark off their territory they will rub their wrists, ankles and rears on surfaces to spread their scent. Males will have scent wars to see which one can mate with the female. Ruffed lemurs are very acrobatic and can often be seen doing a somersaults or backflips in the exhibit.
