A primate is a eutherian mammal constituting the taxonomic order Primates. Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs 30 g (1 oz), to the eastern gorilla, weighing over 200 kg (440 lb). There are 376–522 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the 2010s, and three in the 2020s.
The macaques constitute a genus (Macaca) of gregarious Old World monkeys of the subfamily Cercopithecinae. The 23 species of macaques inhabit ranges throughout Asia, North Africa, and Gibraltar. Macaques are principally frugivorous, although their diet also includes seeds, leaves, flowers, and tree bark. Some species, such as the crab-eating macaque, subsist on a diet of invertebrates and occasionally small vertebrates. On average, southern pig-tailed macaques in Malaysia eat about 70 large rats each per year. All macaque social groups are matriarchal, arranged around dominant females.
The crab-eating macaque, also known as the long-tailed macaque and referred to as the cynomolgus monkey in laboratories, is a cercopithecine primate native to Southeast Asia. A species of macaque, the crab-eating macaque has a long history alongside humans; it has been alternately seen as an agricultural pest, sacred animal in some temples, and more recently, the subject of medical experiments.
Old World monkey is the common English name for a family of primates known taxonomically as the 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. Phylogenetically, they are more closely related to apes than to New World monkeys. They diverged from a common ancestor of New World monkeys around 45 to 55 million years ago.
Simian immunodeficiency virus (SIV) is a species of retrovirus that cause persistent infections in at least 45 species of African non-human primates. Based on analysis of strains found in four species of monkeys from Bioko Island, which was isolated from the mainland by rising sea levels about 11,000 years ago, it has been concluded that SIV has been present in monkeys and apes for at least 32,000 years, and probably much longer.
The rhesus macaque, colloquially rhesus monkey, is a species of Old World monkey. There are between six and nine recognised subspecies that are split between two groups, the Chinese-derived and the Indian-derived. Generally brown or grey in colour, it is 47–53 cm (19–21 in) in length with a 20.7–22.9 cm (8.1–9.0 in) tail and weighs 5.3–7.7 kg (12–17 lb). It is native to South, Central, and Southeast Asia and has the widest geographic range of all non-human primates, occupying a great diversity of altitudes and a great variety of habitats, from grasslands to arid and forested areas, but also close to human settlements. Feral colonies are found in the United States, thought to be either released by humans or escapees after hurricanes destroyed zoo and wildlife park facilities.
Before humans went into space in the 1960s, several other animals were launched into space, including numerous other primates, so that scientists could investigate the biological effects of spaceflight. The United States launched flights containing primate passengers primarily between 1948 and 1961 with one flight in 1969 and one in 1985. France launched two monkey-carrying flights in 1967. The Soviet Union and Russia launched monkeys between 1983 and 1996. Most primates were anesthetized before lift-off.
The lion-tailed macaque, also called wanderoo, is an Old World monkey endemic to the Western Ghats of South India.
The Monkey World Ape Rescue Centre is a 65-acre (26.3 ha) ape and monkey sanctuary and rescue centre near Wool, Dorset, England.
Social grooming is a behavior in which social animals, including humans, clean or maintain one another's body or appearance. A related term, allogrooming, indicates social grooming between members of the same species. Grooming is a major social activity, and a means by which animals who live in close proximity may bond and reinforce social structures, family links, and build companionships. Social grooming is also used as a means of conflict resolution, maternal behavior and reconciliation in some species. Mutual grooming typically describes the act of grooming between two individuals, often as a part of social grooming, pair bonding, or a precoital activity.
James Michael Cronin MBE was the American co-founder in 1987 of Monkey World in Dorset, England, a sanctuary for abused and neglected primates. He was widely acknowledged as an international expert in the rescue and rehabilitation of abused primates, and in the enforcement of international treaties aimed at protecting them from illegal trade and experimentation.
Chimfunshi Wildlife Orphanage is a sanctuary for chimpanzees, located in Zambia's Copperbelt Province. Chimfunshi started as a family-run wildlife orphanage, and today Chimfunshi is managed by a board of trustees to ensure the long-term sustainability of the sanctuary. Chimfunshi was founded in 1983 when a game ranger brought a badly wounded infant chimpanzee to the cattle ranch of David and Sheila Siddle. The Siddles nursed that chimp – named "Pal" – back to health, thereby establishing a tradition of care and respect that forms the legacy of the sanctuary. Once word of Pal's recovery spread, the Siddles were inundated with orphaned chimpanzees. Although many of the chimpanzees were confiscated from poachers who attempted to smuggle the infants into Zambia for sale as pets, an equally large number were rescued from dilapidated zoos and circuses from all over Africa, Asia, Europe and South America. With over 1200 chimpanzees, Chimfunshi is now one of the largest chimpanzee sanctuaries in the world.
The International Primate Protection League (IPPL) is a not-for-profit animal welfare organization founded in 1973 in Thailand by Shirley McGreal.
Experiments involving non-human primates (NHPs) include toxicity testing for medical and non-medical substances; studies of infectious disease, such as HIV and hepatitis; neurological studies; behavior and cognition; reproduction; genetics; and xenotransplantation. Around 65,000 NHPs are used every year in the United States, and around 7,000 across the European Union. Most are purpose-bred, while some are caught in the wild.
Indira Gandhi Zoological Park is located amidst Kambalakonda Reserve Forest in Visakhapatnam, Andhra Pradesh, India. It is the third largest zoo in the country.
Cousins is a nature documentary TV series produced by the BBC Natural History Unit in Bristol, England, first transmitted in the UK on BBC One in August 2000. The series looks at the primates, the closest living relatives to human beings.
Sexual swellings are enlarged areas of genital and perineal skin occurring in some female primates that vary in size over the course of the menstrual cycle. Thought to be an honest signal of fertility, male primates are attracted to these swellings; preferring, and competing for, females with the largest swellings.
Alopecia in animals is a condition where locations on the body surface that are typically covered in hair, contain areas where hair is absent, and is a condition that can affect other animals besides humans. Alopecia is a condition that can affect wild organisms and captive organisms, however, the condition tends to be more prominent in captive contexts. Development of alopecia in animals is usually the sign of an underlying disease. Some animals may be genetically predisposed to hair loss, while in some it may be caused by hypersensitivity or nutritional factors. These include Moluccan cockatoos, spectacled bears, hedgehogs, raccoons, squirrels, baboons, and chimpanzees since they share 98% of human genes. Others that are selectively bred to have baldness include rabbits, guinea pigs, Syrian hamsters, mice, rats, and cats. Environmental enrichment has been used in some cases to mitigate certain behaviours that cause hair loss, improve alopecia, and address welfare concerns.
