  2. New World monkey - Wikipedia

    en.wikipedia.org/wiki/New_World_monkey

    New World monkeys are the only monkeys with prehensile tails—in comparison with the shorter, non-grasping tails of the anthropoids of the Old World. Prehensility has evolved at least two distinct times in platyrrhines, in the Atelidae family (spider monkeys, woolly spider monkeys, howler monkeys, and woolly monkeys), and in capuchin monkeys ...

    en.wikipedia.org/wiki/List_of_platyrrhines

    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 ...

  4. Howler monkey - Wikipedia

    en.wikipedia.org/wiki/Howler_monkey

    Howler monkeys (genus Alouatta, monotypic in subfamily Alouattinae) are the most widespread primate genus in the Neotropics and are among the largest of the platyrrhines along with the muriquis (Brachyteles), the spider monkeys (Ateles) and woolly monkeys (Lagotrix). The monkeys are native to South and Central American forests.

  5. Evolution of color vision in primates - Wikipedia

    en.wikipedia.org/wiki/Evolution_of_color_vision...

    In nearly all species of platyrrhines (New World monkeys) males and homozygous females are dichromats, while heterozygous females are trichromats, a condition known as allelic or polymorphic trichromacy. Among platyrrhines, the exceptions are Alouatta (routine trichromats) and Aotus (routine monochromats). [4] [5]

  6. Old World monkey - Wikipedia

    en.wikipedia.org/wiki/Old_World_monkey

    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 ...

  7. Haplorhini - Wikipedia

    en.wikipedia.org/wiki/Haplorhini

    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.

    Here's another list of monkeys: platyrrhines, or "New World monkeys", #5 in the order Primates and #34 overall for mammals. This took a while; the last couple of lists were 14 and 28 species, but this one is a much larger 160. Turns out South America is filled with a wide variety of little monkeys!

  9. Callitrichidae - Wikipedia

    en.wikipedia.org/wiki/Callitrichidae

    Callitrichids typically live in small, territorial groups of about five or six animals. Their social organization is unique among primates, and is called a "cooperative polyandrous group". This communal breeding system involves groups of multiple males and females, but only one female is reproductively active.
