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 ...

Brown spider monkey (Ateles hybridus) Platyrrhini is a parvorder of primates. Members of this parvorder are called platyrrhines, or New World monkeys, and include marmosets, tamarins, and capuchin, squirrel, night, titi, saki, howler, spider, and woolly monkeys. Platyrrhini is one of three clades that form the suborder Haplorrhini, itself one of two suborders in the order Primates. They are ...
The Old World species are divided into apes and monkeys depending on the number of cusps on their molars: monkeys have four, apes have five [73] - although humans may have four or five. [79] The main hominid molar cusp ( hypocone ) evolved in early primate history, while the cusp of the corresponding primitive lower molar (paraconid) was lost.
The population of the species has radically decreased over the past decade. [8] Silky sifaka: Propithecus candidus: 250 [9] CR [9] [9] Estimate is believed to be a maximum. [9] Tonkin snub-nosed monkey: Rhinopithecus avunculus: 250 [10] CR [10] [10] Barbara Brown's titi: Callicebus barbarabrownae: 260 [11] CR [11] [11] Minimum estimation. [11 ...
The 158 extant species of Cercopithecidae are divided into two subfamilies: Cercopithecinae, containing 78 baboon, guenon, macaque, and other monkey species divided between thirteen genera, and Colobinae, containing 80 colobus, lutung, and other monkey species divided between ten genera. Dozens of extinct prehistoric cercopithecoid species have ...
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 ...
