Old World monkeys are primates in the family Cercopithecidae. Twenty-four genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons, red colobus and macaques. Common names for other Old World monkeys include the talapoin, guenon, colobus, douc, vervet, gelada, mangabey, langur, mandrill, surili (Presbytis), patas, and proboscis monkey.
Talapoins are the two species of Old World monkeys classified in genus Miopithecus. They live in central Africa, with their range extending from Cameroon and the Democratic Republic of the Congo to Angola.
The mantled guereza, also known simply as the guereza, the eastern black-and-white colobus, or the Abyssinian black-and-white colobus, is a black-and-white colobus, a type of Old World monkey. It is native to much of west central and east Africa, including Cameroon, Equatorial Guinea, Nigeria, Ethiopia, Kenya, Tanzania, Uganda and Chad. The species consists of several subspecies that differ in appearance. It has a distinctive appearance, which is alluded to in its name; the long white fringes of hair that run along each side of its black trunk are known as a mantle. Its face is framed with white hair and it has a large white tail tuft.
The silvery lutung, also known as the silvered leaf monkey or the silvery langur, is an Old World monkey. It is arboreal, living in coastal, mangrove, and riverine forests in Peninsular Malaysia, Sumatra, Borneo, Java, and other nearby islands.
De Brazza's monkey is an Old World monkey endemic to the riverine and swamp forests of central Africa. The largest species in the guenon family, it is one of the most widespread arboreal African primates. Aside from size, it can be differentiated from other cercopithecus monkeys by its orange diadem and white beard. Due to its cryptic nature, the species is not well documented in all of its habitats but has shown unique traits, such as pair-bonding and aggressive behavior towards other guenons.
The mona monkey is an Old World monkey that lives in western Africa between Ghana and Cameroon. The mona monkey can also be found on the island of Grenada as it was transported to the island aboard slave ships headed to the New World during the 18th century. This guenon lives in groups of up to thirty-five in forests. It mainly feeds on fruit, but sometimes eats insects and leaves. The mona monkey has brown agouti fur with a white rump. Its tail and legs are black and the face is blue-grey with a dark stripe across the face. The mona monkey carries food in cheek pouches.
The pale spear-nosed bat is a species of phyllostomid bat from South and Central America.
Wolf's mona monkey, also called Wolf's guenon, is a colourful Old World monkey in the family Cercopithecidae. It is found in central Africa, primarily between the Democratic Republic of the Congo and Uganda. It lives in primary and secondary lowland rainforest and swamp forest.
The black colobus, or satanic black colobus, is a species of Old World monkey belonging to the genus Colobus. The species is found in a small area of western central Africa. Black colobuses are large, completely covered with black fur, and like all other Colobus monkeys, do not have a thumb. The species has faced large declines in population due to habitat destruction and hunting by humans, and was consequently listed as Vulnerable on the IUCN Red List in 1994.
The whistling cisticola is a species of bird in the Cisticolidae family. It can be found in several regions within Africa, such as Angola, Benin, Burundi, Cameroon, Central African Republic, Republic of the Congo, Ivory Coast, Gabon, Gambia, Ghana, Guinea, Kenya, Liberia, Mali, Nigeria, Senegal, Sierra Leone, Sudan, Togo, Uganda, and Zambia. Its natural habitats include subtropical or tropical dry forests, dry savanna, and moist savanna.
The moustached guenon or moustached monkey is a species of primate in the family Cercopithecidae. It is found in Angola, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, and Gabon.
The crested mona monkey, also known as the crowned guenon, crowned monkey, golden-bellied guenon, or golden-bellied monkey,, is a species of African primate in the family Cercopithecidae found in west central Africa.
The red-legged sun squirrel is a species of rodent in the family Sciuridae, also commonly known as the isabelline red-legged sun squirrel. It is native to tropical western and central Africa where its range extends from Senegal in the west, through Nigeria and the Republic of Congo to Uganda and Tanzania in the east. Its natural habitats are subtropical or tropical moist lowland forests and moist savanna. This species is thought to be common and has a very wide distribution, so the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The Gabon talapoin, also known as the northern talapoin, is a small species of African monkey native to riparian habitats in Cameroon, Equatorial Guinea, Gabon, the western Republic of the Congo and the far western Democratic Republic of Congo. It may have been introduced to Bioko and the Canary Islands. Classified in the genus Miopithecus, it was given the name Miopithecus ogouensis, based on the River Ogooué, distinguishing it from the other species, the Angolan talapoin, also known as Miopithecus talapoin.
The Gabon bushbaby is a species of primate in the family Galagidae found in Cameroon, Gabon, and the Republic of the Congo. Its head and body length is 8.5 in with a 10-in tail, and it weighs about 10 oz. It lives in evergreen tropical rainforests and eats primarily fallen fruit, but also some arthropods.
The black-crowned Central American squirrel monkey is a subspecies of the Central American squirrel monkey. Its range is restricted to the Pacific coast of western Panama to the western portion of the Chiriquí Province and of southern Costa Rica, south of the Rio Grande de Terraba, including the Osa Peninsula. It is the subspecies of Central American squirrel monkey seen in Corcovado National Park in Costa Rica. Its type locality is David, Panama, but its range apparently no longer extends that far east.
The Eastern Congolian swamp forests are a fairly intact but underresearched ecoregion of the tropical and subtropical moist broadleaf forests biome. It is located within the Democratic Republic of the Congo. This is the eastern half of one of the largest areas of swamps in the world.
The drill is a primate of the family Cercopithecidae, related to baboons and even more closely to mandrills.
The red-tailed monkey, also known as the black-cheeked white-nosed monkey, red-tailed guenon, redtail monkey, or Schmidt's guenon, is a species of primate in the family Cercopithecidae.
The Guianan squirrel monkey is a species of squirrel monkey from Guiana, Venezuela and Brazil. S. sciureus formerly applied to Humboldt's squirrel monkey and Collins' squirrel monkey, but genetic research in 2009 and 2015 revealed that these are distinct species.
