The Vervet monkey (Chlorocebus pygerythrus), or just simply Vervet, is an African Old World monkey. This species is classified into the family Cercopithecidae. The term can also refer to all of the members of their genus, Chlorocebus.
Vervets are commonly found around South Africa, where they are classified as vermin. Sources indicate that these monkeys must go through life in constant danger of being killed by people. In South Africa, these creatures can be killed in any method without previously obtaining a permit.
The Vervet monkey inhabits grasslands and mountains up to 1,312 feet (4000 m). Males vary in size from 17.72 to 33.46 in (45 to 85 cm) and weigh between 7.72 to 16.53 lbs (3.5 to 7.5 kg). Females range from 15.75 to 23.62 in (40 to 60 cm) in size and between 5.51 to 12.13 lbs (2.5 to 5.5 kg) in weight. Both have the tail lengths that can vary from 19.69 to 42.28 in (50 to 115 cm).
The Vervet monkey mainly eats fruit. It also supplements its diet with a variety of other foods, including leaves, seeds, insects and small rodents. It lives in groups of 20 or more. Though, the group sizes are often smaller. Its gestation period is 7 months with a single offspring produced. It is known to have a life span of up to 20 years.
The Vervet monkey alarm calls vary greatly depending on the different types of threats to the community. There are distinct calls to warn of invading leopards, snakes, and eagles.
