Cebus capucinus |
The capuchins are the group of New World monkeys classified as genus Cebus.

Capuchins generally resemble the friars of their namesake. Their body, arms, legs and tail are all darkly (black or brown) colored, while the face, throat and chest are white colored, and their head has a black cap. They reach a length of 30 to 56 cm (12 - 22 inches), with tails that are just as long as the body. They weigh up to 1. 3 kg (2 lb, 13 oz), with brains of mass 35-40g. They are considered the most intelligent New World monkeys.
Like most New World monkeys, capuchins are diurnal and arboreal. In Animal behavior, diurnality indicates an Animal that is active during the Daytime and rests during the Night. Arboreal is a word meaning "related to or resembling trees" With the exception of a midday nap, they spend their entire day searching for food. At night they sleep in the trees, wedged between branches. They are undemanding regarding their habitat and can thus be found in many differing areas. Among the natural enemies of the capuchins are large falcons, cats and snakes. A falcon (fɔlkən or fælkən is any Species of raptor in the Genus Falco.

The diet of the capuchins is more varied than other monkeys in the family Cebidae. The Cebidae form one of the four families of New World monkeys now recognised They are omnivores, eating not only fruits, nuts, seeds and buds, but also insects, spiders, bird eggs and small vertebrates. Omnivores (from Latin omne all everything vorare to devour are species that eat both Plants and Animals as their primary Capuchins living near water will also eat crabs and shellfish by cracking their shells with stones.
Easily recognized as the "organ grinder" or "greyhound jockey" monkeys, capuchins are sometimes kept as exotic pets. The organ grinder was a musical novelty street performer of the 19th century and the early part of the 20th century and refers to the operator of a Greyhound jockeys or monkey jockeys are Capuchin monkeys trained to ride racing dogs for sport over a 5/16 mile course An exotic pet is a rare or unusual animal kept as a Pet, or an animal kept as a pet which is not commonly thought of as a pet They are also sometimes used as service animals. Sometimes they plunder fields and crops and are seen as troublesome by nearby human populations. [2] In some regions they have become rare due to the destruction of their habitat.

Social structure
Capuchins live together in groups of 6 to 40 members. These groups consist of related females and their offspring, as well as several males. Usually groups are dominated by a single male, who has primary rights to mate with the females of the group, though the White-headed Capuchin groups are lead by bolth an alpha male and an alpha female. The White-headed Capuchin ( Cebus capucinus) also known as the White-faced Capuchin or White-throated Capuchin, is a medium-sized New World monkey Mutual grooming as well as vocalization serves as communication and stabilization of the group dynamics. These primates are territorial animals, distinctly marking a central area of their territory with urine and defending it against intruders, though outer zones of these areas may overlap. A primate is a member of the biological order Primates ( Latin: "prime first rank" the group that contains Lemurs the Aye-aye
Females bear young every two years following a 160 to 180 day gestation. The young cling to their mother's chest until they are larger, when they move to her back. Adult male capuchins rarely take part in caring for the young. Within four years for females and eight years for males, juveniles become fully mature. In captivity, individuals have reached an age of 45 years, although life expectancy in nature is only 15 to 25 years.
Intelligence
Capuchins are considered the most intelligent New World monkeys and are often used in laboratories. The Tufted Capuchin is especially noted for its long-term tool usage, one of the few examples of primate tool use other than by apes. The Tufted Capuchin ( Cebus apella) also known as Brown Capuchin or Black-capped Capuchin is a New World Primate from South Upon seeing macaws eating palm nuts, cracking them open with their beaks, these capuchins will select a few of the ripest fruits, nip off the tip of the fruit and drink down the juice, then seemingly discard the rest of the fruit with the nut inside. Macaws are small to large often colourful New World Parrots Of the many different Psittacidae (true parrots genera, six are classified as When these discarded fruits have hardened and become slightly brittle, the capuchins will gather them up again and take them to a large flat boulder where they have previously gathered a few river stones from up to a mile away. They will then use these stones, some of them weighing as much as the monkeys, to crack open the fruit to get to the nut inside. Young capuchins will watch this process to learn from the older, more experienced adults.
During the mosquito season, they crush up millipedes and rub the remains on their backs. This acts as a natural insect repellent. An insect repellent is a substance applied to skin clothing or other surfaces which discourages Insects (and Arthropods in general from landing or climbing on that
Self-awareness
When presented with a reflection, capuchin monkeys react in a way that indicates an intermediate state between seeing the mirror as another individual and recognizing the image as self.
Most animals react to seeing their reflection as if encountering another individual they don't recognize. An experiment with capuchins shows that they react to a reflection as a strange phenomenon, but not as if seeing a strange capuchin.
In the experiment, capuchins were presented with three different scenarios:
- Seeing an unfamiliar, same-sex monkey on the other side of a clear barrier
- Seeing a familiar, same-sex monkey on the other side of a clear barrier
- A mirror showing a reflection of the monkey
With scenario 1, females appeared anxious and avoided eye-contact. Males made threatening gestures. In scenario 2, there was little reaction by either males or females.
When presented with a reflection, females gazed into their own eyes and made friendly gestures such as lip-smacking and swaying. Males made more eye contact than with strangers or familiar monkeys but reacted with signs of confusion or distress, such as squealing, curling up on the floor or trying to escape from the test room. [3]
Theory of mind
The question of whether capuchin monkeys have a theory of mind -- whether they can understand what another creature may know or think -- has been neither proven nor disproven conclusively. " Theory of mind " is the ability to attribute mental states—beliefs intents desires pretending knowledge etc If confronted with a knower-guesser scenario, where one trainer can be observed to know the location of food and another trainer merely guesses the location of food, capuchin monkeys can learn to rely on the knower. [4] This has, however, been refuted as conclusive evidence for a theory of mind as the monkeys may have learned to discriminate knower and guesser by other means. [5] Non-human great apes have not been proven to develop a theory of mind either; human children commonly develop a theory of mind around the ages 3 and 4.
Human assistance
Some organizations, such as Helping Hands in Boston, Massachusetts, have been training capuchin monkeys to assist quadriplegics in a manner similar to mobility assistance dogs. The Commonwealth of Massachusetts ( is a state located in the New England region of the northeastern United States. Quadriplegia, also known as tetraplegia, is a Symptom in which a human experiences Paralysis affecting all four limbs although not necessarily total paralysis A mobility assistance dog is a Service dog trained to assist a physically disabled person After being socialized in a human home as infants, the monkeys undergo extensive training before being placed with a quadriplegic. Around the house, the monkeys help out by doing tasks including microwaving food, washing the quadriplegic's face, and opening drink bottles.
