Diurnal, partly arboreal, and mostly terrestrtial. Rhesus macaques are well known as a beligerent species. In a captive study, an average of 18 aggressive acts by each monkey during a 10-hour period were recorded. Their most common threat is a wide-open mouth with staring eyes, which is given by a dominant animal. Submission is signaled by screaming and baring of the teeth because of fear.
