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 ...
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 ...
[48] [49] [50] Generally, extinct non-hominoid simians, including early catarrhines are discussed as monkeys as well as simians or anthropoids, [41] [9] [42] which cladistically means that Hominoidea are monkeys as well, restoring monkeys as a single grouping. It is indicated approximately how many million years ago (Mya) the clades diverged ...
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 ...
For many years, it was considered a subspecies of the Sunda slow loris (N. coucang), until the 2000s when it was promoted to full species status. It is most closely related to the Sunda slow loris and the Bengal slow loris (N. bengalensis). The species has two forms, based on hair length and, to a lesser extent, coloration.
Albert I – (rhesus monkey) the first primate and first mammal launched on a rocket (a June 18, 1948 V-2 flight), although it did not reach space. Albert II – (rhesus monkey) the first primate and first mammal in space, June 14, 1949. Died upon hitting the ground due to a parachute failure
Kayan River slow loris (Nycticebus kayan), a species of slow loris, was first described by Rachel Munds, Anna Nekaris, and Susan Ford. [9] Makandé squirrel galago (Sciurocheirus makandensis), a species of galago, was described by Ambrose. It is found in Gabon. [10]
There are currently 1,258 genera, 161 families, 27 orders, and around 5,937 recognized living species of mammal. [1] Mammalian taxonomy is in constant flux as many new species are described and recategorized within their respective genera and families.
