have been noted for having human-like characteristics, such as hypertension, anxiety, and social and dependent alcohol use. Vervets live in social groups ranging from 10 to 70 individuals, with males changing groups at the time of sexual maturity. Vervet monkeys have four confirmed predators: leopards, eagles, pythons, and baboons. The sighting of each predator elicits an acoustically distinct alarm call. It is believed that vervet monkeys have up to 30 different alarm calls.Mothers can recognize their offspring by a scream alone. A juvenile scream will elicit a reaction from all mothers, yet the juvenile's own mother had a shorter latency in looking in the direction of the scream, as well as an increased duration in her look. Further, mothers have been observed to help their offspring in conflict, yet rarely aided other juveniles.
