Gigantopithecus (from the Ancient Greek ' "giant", and ' "ape") is an extinct genus of ape that existed from perhaps nine million years to as recently as one hundred thousand years ago, at the same period as "Homo erectus" would have been dispersed, in what is now India, Vietnam, China and Indonesia placing "Gigantopithecus" in the same time frame and geographical location as several hominin species. The primate fossil record suggests that the species "Gigantopithecus blacki" were the largest known primates that ever lived, standing up to and weighing as much as , although some argue that it is more likely that they were much smaller, at roughly in height and in weight.

Though similar to "Palaeopropithecus", "Archaeoindris" was significantly larger and more robust. "Archaeoindris" was one of the largest primates to ever evolve, and was the largest-known strepsirrhine primate, weighing an estimated . It was roughly the size of an adult male gorilla, which was first noted by Lamberton.

Sierra Leone has 15 identified species of primates that include bushbaby, monkeys and a great ape, the common chimpanzee which is Sierra Leone's largest primate. Chimpanzees are found across the country with the 2010 chimpanzee census estimated a wild population in excess of 5500 more than double the number previously thought to live in the country. This is the second largest population of the endangered subspecies of western chimpanzee, after Guinea,
with the largest density in the Loma area, 2.69 individuals per km2, and the Outamba, with 1.21 individuals per km2.

The largest primate in the region, excluding humans, is the chacma baboon. A true generalist, it is found in virtually all habitats in South Africa. The other primates in the region are the vervet monkey and the Samango monkey. They are mainly frugivores, although they are true opportunists and may take eggs and nestlings from bird nests.

Gorillas are ground-dwelling, predominantly herbivorous apes that inhabit the forests of central Sub-Saharan Africa. They are classified in the genus Gorilla which is divided into two species: the eastern gorillas and the western gorillas (both critically endangered), and either four or five subspecies. They are the largest living primates. The DNA of gorillas is highly similar to that of humans, from 95 to 99% depending on what is included, and they are the next closest living relatives to humans after the species of "Pan"; the chimpanzees and bonobos.

The eastern gorilla ("Gorilla beringei") is a critically endangered species of the genus "Gorilla" and the largest living primate. At present, the species is subdivided into two subspecies. Grauer's gorilla, formerly known as the eastern lowland gorilla ("G. b. graueri") is more populous, at about 3,800 individuals. The mountain gorilla ("G. b. beringei") has only about 1000 individuals. The International Union for the Conservation of Nature mentioned illegal hunting in its assessment of threats to the species.

Grauer's gorillas and mountain gorillas were previously thought to be two of the three subspecies of one single species, the gorilla ("Gorilla gorilla"). However, genetic research has shown that the two eastern subspecies are far more closely related than the western subspecies: the western lowland gorilla ("G. gorilla gorilla"), which justified the separate classification. The two eastern subspecies are now classified as "G. beringei".

There are two recognised subspecies of eastern gorilla: the mountain gorilla ("Gorilla beringei beringei") of the volcanic slopes of Rwanda, Uganda and eastern Democratic Republic of Congo; and Grauer's gorilla or eastern lowland gorilla ("Gorilla beringei graueri") in eastern Democratic Republic of Congo.

Nyungwe Forest boasts thirteen primate species including chimpanzees and Ruwenzori colobus arboreal monkeys; the Ruwenzori colobus move in groups of up to 400 individuals, the largest troop size of any primate in Africa.
Twenty species of mammals reported by Animal Diversity web of the Museum of Geology University of Michigan are as under.
Primates are the dominant species of fauna in the Nyungwe Forest. The species reported are Ruwenzori colobus, L’Hoest’s monkeys and chimpanzees (largest concentration of 13 species). An amphibian species reported is Hyperolius viridiflavus.

Bangkok, the capital of Thailand, has been called "the most primate city on Earth", being roughly thirty-five times larger than Thailand's second-largest city of Nakhon Ratchasima. Taking the concept from his examination of the primate city during the 2010 Thai political protests and applying it to the role that primate cities play if they are national capitals, Jack Fong's study noted that when primate cities like Bangkok function as national capitals, they are inherently vulnerable to insurrectionary dynamics by the subaltern, and the dispossessed. He cites the simple fact that most primate cities serving as national capitals contain major headquarters for the country. Thus, logistically, it is rather "efficient" for national targets to be contested since they are all located within one major urban environment.

Opened originally as the Primate & Cat Building in 1975, the Primate, Cat & Aquatics Building houses one of the largest collections of primate species in North America, including western lowland gorillas, New World monkeys, aye-ayes, and several species of lemur. However, the building does not house the Zoo's entire primate population; numerous primate species can also be found in the RainForest. In 1985, the Cleveland Aquarium permanently closed and donated its collection of exotic fishes and invertebrates to the Metroparks Zoo. A section of the Primate & Cat building was renovated to accommodate the new Aquatics section, which currently features 35 salt- and freshwater exhibits including a variety of sharks, piranhas, a giant Pacific octopus, electric eels, and hundreds of living coral.

Eighty-two percent of primate procedures in the UK in 2006 were in applied studies, which the Home Office defines as research conducted for the purpose of developing or testing commercial products. Toxicology testing is the largest use, which includes legislatively required testing of drugs. The second largest category of research using primates is "protection of man, animals, or environment", accounting for 8.9% of all procedures in 2006. The third largest category is "fundamental biological research,", accounting for 4.9% of all UK primate procedures in 2006. This includes neuroscientific study of the visual system, cognition, and diseases such as Parkinson's, involving techniques such as inserting electrodes to record from or stimulate the brain, and temporary or permanent inactivation of areas of tissue.

Prosen’s interest in empathy prepared him well for his later work with primates, in particular bonobos, considered to be the most empathetic of all primates. Since 1998, he has been psychiatric consultant to the Bonobo Species Preservation Society, assisting primatologists working with one of the largest collections of captive bonobo primates in the world at the Milwaukee County Zoo, studying bonobo culture and development. This work has led to Prosen receiving numerous consultations from the United States and other parts of the world concerning psychological and other problems in primates. Recently, the rehabilitation of an emotionally disturbed young bonobo named "Brian" generated substantial publicity, including a story in "The Atlantic" as well as appearing in Laurel Braitman's 2014 book "Animal Madness".
