Green monkey

The green monkey is a sexually dimorphic species, with males typically being slightly larger than females. Wild adult males weigh between and measure between , while the females usually weigh between and measure between . == Habitat and distribution ==

The green monkey can be found in a wide range of wooded habitats, ranging from very dry Sahel woodland to the edge of rainforests. It is also commonly seen in coastal regions, where known to feed on seashore foods such as crabs. It has been introduced to the Cape Verde islands off north-western Africa (islands of Santiago and Brava only) as early as the second half of the 16th century, and the West Indian islands of Saint Kitts, Nevis, Saint Martin, and Barbados, == Behavior ==

As other members of the genus Chlorocebus, the green monkey is highly social and usually seen in groups. They usually live in groups of 7 up to 80 individuals. Within these groups, there is distinct social hierarchy evidenced by grooming behaviors and gender relationships. Green monkeys are known to communicate both verbally and non-verbally. They have distinct calls which they use to warn others in the group of predators, and even have specific calls for specific predators. Body language, such as the display of brightly colored genitalia, is also used to communicate danger, but can also be used as a way of establishing dominance. It has also been documented that green monkeys may use facial expressions to express their emotional state. Reproduction Green monkeys live in a polygynous society, revolving around the alpha males. The alpha males have control over social interactions and mating between other males and females in the group. These monkeys are seasonal breeders, breeding during the April to June months (October and November in the Nyes area North West of Thies), during which rainfall is the heaviest. It is during these rainy seasons that fruit is most abundant, so it is speculated that green monkeys schedule their breeding around this time, when resources are most abundant. They breed about once a year, with males reaching sexual maturity in five years, females in two. Despite infant mortality being fairly high, at roughly 57%, green monkeys are known to be heavily invested in their offspring, with mothers taking care of their young for about a year before letting them venture out as individual adults. ==Gallery==

In West Africa, leopards, martial eagles, and pythons (Python) are primary predators of green monkeys. In the Caribbean and the West Indies, humans are the only documented predators.In Fongoli, Senegal, male Western chimpanzees are observed to prey more on green monkeys. ==References==
