8/24/2023 0 Comments Old world vs new world monkeys![]() As their taxonomic names suggest, New World (platyrrhine) and Old World (catarrhine) monkeys are distinguished by the form of the nose. The New World monkeys are the platyrrhines (“flat-nosed”), a group comprising five families. Old World monkeys all belong to one family, Cercopithecidae, which is related to apes and humans, and together they are classified as catarrhines (meaning “downward-nosed” in Latin). Monkeys are arranged into two main groups: Old World and New World. Please label your submissions with user flair after submitting them.

After reproduction, the males also help the females to care for the offspring.A place to discuss all things biology! We welcome people and content from all related fields. Although the skin around the genitals does not swell during oestrus, the scent glads produce enough pheromones to communicate with sexual mates for reproduction. Their nose is flat, and the nostrils are located far apart. Most of the time these monkeys spend their time on trees and most of their features could be understood as adaptations for arboreal lifestyles. In addition, their tail is long and strong, so that it can bear the weight of the body. One of the most important features of these primates is the prehensile tail, which is extremely useful for an arboreal lifestyle. ![]() They are distributed predominantly in the South American tropical regions, and some species are found in Mexico. There are about 53 described species of new world monkeys, and they are distributed in tropical regions of the Americas and they are never found in cold-temperate climates. New world monkeys are the native primates of the Americas. However, sometimes males join the females to provide care. The females usually provide the parental care, and the males do not involve with the females, to care for their young. ![]() One of the important features of the old world monkeys is that the skin around the genital area starts to swell when the females come to oestrus, which is a way of communication to attract the opposite sexes. Therefore, the competition for females is high among males, and the most dominant one gets the maximum number of females to mate with him. The social groups consist of both males and females, and the number of males is considerable in a troop. In addition, the nostrils are located closer than not, and the direction of the nares could be either forward or downward depending on the species. The downward-facing nose of the protruded face is noticeable about these primates. It would be important to notice that their tail is not prehensile, and some of the old world primates do not even have tails. Old world monkeys could be either arboreal or terrestrial, but some species are found in both habitats. There are almost 80 species of old world primates, and they are distributed throughout the tropics of the Afro Eurasia, but some are found even outside tropical climates. Native primates of these two regions are important to consider, as there are many exhibited differences between them.Īccording to the definition, old world monkeys are the native primates found in Africa, Asia, and Europe (Afro Eurasia). After that, the two adjectives new world and old world were used to refer the fauna of those two regions of the world accordingly. ![]() After Christopher Columbus had discovered the America, it was named the new world and all the landmasses located east to the Atlantic Ocean were referred as the old world.
