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 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 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.
Cercopithecoides is an extinct genus of colobine monkey from Africa which lived during the latest Miocene to the Pleistocene period. There are several recognized species, [ 2 ] with the smallest close in size to some of the larger extant colobines, and males of the largest species weighed over 50 kilograms (110 lb).
Members of this family are called cercopithecoids, or Old World monkeys, and include baboons, colobuses, guenons, lutungs, macaques, and other types of monkeys. Cercopithecoidea contains only a single family, Cercopithecidae , and includes nearly half of the species in the suborder Haplorhini , itself one of two suborders in the order Primates.
Ischial callosities on a Sulawesi crested macaque Macaca nigra. All Old World monkeys, gibbons, and some chimpanzees have pads on their rears known as ischial callosities. [1] [2] The pads enable the monkeys to sleep sitting upright on thin branches, beyond reach of predators, without falling.
Of the three monkey species to have had any lasting presence in Florida, the other two being African vervet monkeys and South American squirrel monkeys, the Rhesus macaques have endured the longest and are the only ones to show continual population growth. The species' adaptable nature, generalized diet, and larger size as to reduce the chance ...
The red-shanked douc (Pygathrix nemaeus) is an arboreal and diurnal Old World monkey belonging to the Colobinae subfamily. They are endemic to Laos, Vietnam, and Cambodia. They are known for their bright colors and exhibit sexual dimorphism through their body size.
