The tails of Old World monkeys are not prehensile, unlike those of the New World monkeys (platyrrhines). The distinction of catarrhines from platyrrhines depends on the structure of the rhinarium, and the distinction of Old World monkeys from apes depends on dentition (the number of teeth is the same in both, but they are shaped differently ...
The parvorder Catarrhini / k æ t ə ˈ r aɪ n aɪ / (known commonly as catarrhine monkeys, Old World anthropoids, or Old World monkeys) consists of the Cercopithecoidea and apes (Hominoidea). In 1812, Geoffroy grouped those two groups together and established the name Catarrhini, "Old World monkeys", (" singes de l'Ancien Monde " in French ).
The Cercopithecinae are a subfamily of the Old World monkeys, which comprises roughly 71 species, including the baboons, the macaques, and the vervet monkeys.Most cercopithecine monkeys are limited to sub-Saharan Africa, although the macaques range from the far eastern parts of Asia through northern Africa, as well as on Gibraltar.
All old world monkeys and apes are trichromats, but new world monkeys are polymorphic trichromats, meaning that males and homozygous females are dichromats while heterozygous females are trichromats (with the exceptions of howler monkeys and night monkeys, who have more and less robust color vision respectively).
Black-and-white colobuses (or colobi) are Old World monkeys of the genus Colobus, native to Africa. They are closely related to the red colobus monkeys of genus Piliocolobus. [1] There are five species of this monkey, and at least eight subspecies. [1] They are generally found in high-density forests where they forage on leaves, flowers and fruit.
Mandrillus is a genus of large Old World monkeys distributed throughout central and southern Africa, consisting of two species: M. sphinx and M. leucophaeus, the mandrill and drill, respectively. [4] Mandrillus , originally placed under the genus Papio as a type of baboon , is closely related to the genus Cercocebus . [ 5 ]
The simians include catarrhines (Old World monkeys and apes, including humans), and the platyrrhines (New World monkeys). Haplorhini was proposed by Pocock in 1918 when he realized the tarsiers were actually sister to the monkeys rather than the lemurs, also following findings of Hugh Cuming 80 years earlier and Linnaeus 160 years earlier.
The gelada (Theropithecus gelada, Amharic: ጭላዳ, romanized: č̣əlada, Oromo: Jaldeessa daabee), sometimes called the bleeding-heart monkey or the gelada baboon, is a species of Old World monkey found only in the Ethiopian Highlands, living at elevations of 1,800–4,400 m (5,900–14,400 ft) above sea level.
