A grivet (Chlorocebus aethiops) is an Old World monkey that is found in some sub-Saharan countries of Africa. These grivet monkeys cross range with a closely related species of monkey called the vervet monkey in the southern part of their range.
Although they are common within their restricted range in Africa, very little is known about these middle-sized black monkeys. The widespread species requires more data regarding population distribution. They are found most abundantly in Ethiopia and Dunbar.
In the past, there are claims that their range extended along the Nile valley up to southern parts of Egypt. However, there are no verified records of grivets from those areas.
They are territorial in nature. Monkeys spend most of their time on the ground and forage on the ground; however, the monkeys are comfortable on trees as well. These monkeys can adapt to any type of habitat ranging from urban developments to rural environments.
However, the groups of grivet monkeys face a few threats in their native regions. These monkeys have commercial importance; therefore, they are hunted on a large scale.
Their population is also threatened by ongoing deforestation and the uncontrolled felling of trees that have affected their habitat negatively. They are also minimally threatened by some of their common predators in the wild although.

Grivet Interesting Facts
What type of animal is a grivet?
A grivet (Chlorocebus aethiops) is a type of monkey.
What class of animal does a grivet belong to?
The grivet monkey (Chlorocebus aethiops) of the primates order and Cercopithecidae family belongs to the class of mammals, the common class for all warm-blooded animals.
How many grivets are there in the world?
The total population of the grivet found all over the world has not been quantified. Currently, the monkey species is believed to follow a stable population pattern without getting threatened by any major factor.
Where does a grivet live?
Grivets are endemic to the northeastern parts of Africa. Currently, these monkeys are found along the east coast of the White Nile, to the south of the Omo River, and east of the rift valley in Ethiopia, parts of southeast and south Sudan, and Eritrea. They are the northernmost primate extending the woolly monkey and capuchin monkeys.
What is a grivet's habitat?
Grivet monkeys ideally prefer to live in savanna woodlands near a water source. They are found in open woodlands, mosaic forest grasslands, and steppes. The presence of a water source near their inhabited lands is a necessity since they need to drink water every day. They are also found in the tablelands of bush steppe forest in the south.
Who do grivets live with?
Grivet monkeys are extremely gregarious animals like the vervet monkey. They live by forming small groups.
The female monkeys live in a single group throughout their life, but males search for new groups when they mature. Like all other primates, grooming plays a considerable role in the social bonds of the grivet monkeys. The number of grivets present in a single group ranges between 6-20 individuals with an average of 12 monkeys.
How long does a grivet live?
The average grivet lifespan is estimated to be 31 years in the wild.
How do they reproduce?
The reproduction process of grivets is similar to the reproduction methods of the vervet monkey. The breeding season of these monkeys lasts from July to November.
The babies are born during the premonsoon season between April to May. Females mate with very few males throughout their lifetime, while males might have several female partners. The breeding males are alerted by the changes in the shape of the reproductive organs of females.
The female genitalia swells during their heat or estrus period. This indicates to males that they are ready to breed.
Grooming and cleaning are also used as courtship strategies by the grivet monkey. Females give birth to one infant after a gestation period of two to three months. The gestation period might last up to six months in some individuals.
Male grivets leave immediately after mating. The babies live with their mothers in their natal group. These groups consist of several females all of them share the responsibility of raising the offspring together.
The babies are weaned six months after they are born. Females reach sexual maturity at four years, while males reach sexual maturity after five years old. Young males leave the natal group after they are sexually mature and search for a new group.
What is their conservation status?
The grivet species of monkey are listed as a species of Least Concern in the IUCN Red List. These monkeys have a moderately large range, and they are distributed widely throughout their range. This shows that they have a more or less stable population without the threat of any major threat.
