There is no fixed definition of a large primate, it is typically assessed empirically. [1] Primates exhibit the highest levels of sexual dimorphism amongst mammals, [2] therefore the maximum body dimensions included in this list generally refer to male specimens. Mandrills and baboons are monkeys; the rest of the species on this list are apes.
Old World monkeys are primates in the family Cercopithecidae (/ ˌ s ɜːr k oʊ p ɪ ˈ θ ɛ s ɪ d iː /). Twenty-four genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons (genus Papio), red colobus (genus Piliocolobus), and macaques (genus Macaca).
The order Primates consists of 505 extant species belonging to 81 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 81 genera can be grouped into 16 families; these families are divided between two named suborders and are grouped in those suborders into named clades, and some of these families are subdivided into named ...
Monkeys comprise two monophyletic groups, New World monkeys and Old World monkeys, but is paraphyletic because it excludes hominoids, superfamily Hominoidea, also descendants of the common ancestor Simiiformes. Apes as a whole, and the great apes, are paraphyletic if the terms are used such that they exclude humans.
The Hominidae (/ h ɒ ˈ m ɪ n ɪ d iː /), whose members are known as the great apes [note 1] or hominids (/ ˈ h ɒ m ɪ n ɪ d z /), are a taxonomic family of primates that includes eight extant species in four genera: Pongo (the Bornean, Sumatran and Tapanuli orangutan); Gorilla (the eastern and western gorilla); Pan (the chimpanzee and the bonobo); and Homo, of which only modern humans ...
The mandrill is the most sexually dimorphic primate, [22] and it is the largest monkey. [23] Females are less stocky and have shorter, flatter snouts. [ 19 ] Males have a 70–95 cm (28–37 in) head-body length and weigh 19–30 kg (42–66 lb) while females have a 55–70 cm (22–28 in) head-body length and weigh 10–15 kg (22–33 lb). [ 24 ]
Gorillas are the largest living primates, reaching heights between 1.25 and 1.8 m (4 ft 1 in and 5 ft 11 in), weights between 100 and 270 kg (220 and 600 lb), and arm spans up to 2.6 m (8 ft 6 in), depending on species and sex. They tend to live in troops, with the leader being called a silverback.
Sumatran orangutan (Pongo abelli) Hominoidea is a superfamily of primates. Members of this superfamily are called hominoids or apes, and include gorillas, chimpanzees, orangutans, gibbons, bonobos, and humans. Hominoidea is one of the six major groups in the order Primates. The majority are found in forests in Southeastern Asia and Equatorial Africa, with the exception of humans, which have ...
