Types of New-World Monkeys

    New-World Monkeys

    The term “New World monkey” is a broad label that refers to any species that falls under one of the five taxonomic families of the Ceboidea superfamily: Cebidae, Callitrichidae, Atelidae, Pitheciidae, and Aotidae.

    There are 23 genera and 179 species of New World monkeys distributed across southern Mexico and South and Central America.

    Many different types of New World monkeys exist, including howler monkeys, marmosets, capuchins, sakis, night monkeys, tamarins, and more.

    Characteristics of New-World Monkeys

    Here are the main characteristics shared by New World monkeys:

    • new world monkey diet

      Diet

      The diet of New World monkeys cannot simply be generalized—it largely depends on the particular species in question. Nevertheless, some of the common foods eaten by these monkeys are fruits, insects, tree gums, and seeds; many species are primarily frugivores or insectivores[1].

    • New-World Monkey Reproduction

      Gestation/Reproduction

      For the most part, smaller New World monkeys tend to stick to monogamy, while larger species are more likely to be polyamorous[2]. Interestingly, unlike many other primate groups, female New World monkeys do not have periods. It should also be noted that although the gestation period of New World monkeys varies by species, it is usually around 145 days (about 5 months).

    • New-World Monkey Tail

      Tail

      All New World monkeys possess tails; in certain species, they are prehensile, meaning they can be used to grasp and hold objects, acting like a fifth limb of sorts[5].

      One of the most well-known uses in monkeys is to dangle from a tree branch (by tightly wrapping the prehensile tail around it). It should be noted that only 4 genera of New World monkeys have these useful appendages: Ateles (spider monkeys), Lagothrix (woolly monkeys), Brachyteles (woolly spider monkeys), and Cebus (capuchin monkeys)[6].

    • New-World Monkey Body Size

      Body Size

      In general, New World monkeys are mainly small to medium-sized. Specifically, the smallest New World monkey species in the world is the pygmy marmoset (Finger Monkey) (Cebuella pygmaea); it weighs around 3 to 5 ounces and can be 4 to 6 inches long[7].

      On the other hand, one of the largest New World monkey species is the Yucatan black howler monkey (Alouatta pigra), which can weigh up to 11.4 kilograms, and is about 26 inches long[8].

    • New-World Monkey Teeth

      Teeth

      All New World Monkeys share a dental formula of 2.1.3.3[9]. This essentially means that each quadrant of the mouth has 2 incisors (which are used to bite food directly) and 1 canine (which is used to tear food), as well as 3 molars and premolars each (both of which are used to chew food).

    • New-World monkey social behavior

      Social Behavior

      The social groups and structures of New World monkeys vary between species. For instance, some genera live in small groups consisting of only close family (mates and children). Conversely, other genera live in large groups made up of many different families; these groups can be made up of as many as 50 to 60 individuals [10].

    • New-World Monkey Eyes

      Eyes

      New-World monkeys are known for their large eyes; however, the quality of their color vision varies between species. For example, in some species, all males possess dichromatic vision (meaning they only have two cone cells in their retinas that perceive color), while females’ vision can either be trichromatic (which means they have three cone types in their retinas), or dichromatic like males[11].

      On the other hand, all species of howler monkeys, male and female, have been found to have a trichromatic vision[12].

    • New-World Monkey Limbs

      Limbs

      All New-World monkeys possess relatively long limbs and have a locomotor pattern of quadrupedal walking[3]. It is also worth mentioning that the thumbs of New World monkeys, unlike Old World monkeys, are not opposable (meaning they cannot move independently from the hand)[4].

    Types of New-World Monkeys

    Alta Floresta Titi

    Species Name: Plecturocebus grovesi

    Species Name: Chiropotes satanas
    The black-bearded saki is a species of bearded saki, a species of New World monkey, one of the five remaining monkeys of its kind. Another striking feature is its signature beards.

    Black Capuchin

    Species Name: Sapajus nigritus
    The black capuchin, also called the black-horned capuchin, is a capuchin monkey native to the Atlantic rainforest of southeastern Brazil and extreme northeastern Argentina.

    Brown Weeper Capuchin

    Species Name: Cebus brunneus

    Species Name: Chiropotes israelita
    The brown-backed bearded Saki is one of 5 species of bearded Saki, a New World monkey species. Bearded sakis have a unique appearance.
