Wikipedia: The vervet monkeys or green monkeys are medium-sized primates from the family of Old World monkeys. There are six species currently recognized, although some classify them all as a single species with numerous subspecies. Either way, they make up the entirety of the genus Chlorocebus.

The native range of these monkeys is sub-Saharan Africa from Senegal and Ethiopia down to South Africa. However, in previous centuries, a number of these monkeys were taken as pets by slavers, and were transported across the Atlantic Ocean to the Caribbean islands, along with the enslaved Africans. The monkeys subsequently escaped or were released and became naturalized. The descendents of those populations are found on the West Indian islands of Barbados, Saint Kitts, Nevis, Anguilla, and Saint Maarten. A colony also exists in Broward County, Florida.[2]
