These classic monkeys, each with its own characteristics, do you know them all?

Monkeys are members of three species of ape primates, primates are the population of the animal kingdom, monkeys generally have developed brains, the orbits are facing forward, the orbital spacing is narrow, the toes (fingers) of the hands and feet are separated, the thumbs are flexible, and most can be compared with other proto-monkey suborders and ape suborders.

Monkey

Most of the skulls of primates have large cranial cranial cavities and are spherical, which is due to the shortening of the jaw and the flattening of the face; the development of the posterior orbital process to form a bone eye ring, or a complete closure to form the eye socket; most species have a short nose, and their sense of smell is inferior to that of sight, touch, and hearing; and some lower species have a highly developed olfactory center in the brain and act largely on the sense of smell. Some lemurs have a longer nose. The nasal bones of the genus Golden Snub-nosed Monkey and the Genus Torpedo-tailed Langur degenerate, forming upward-leaning nostrils. The nose of the genus Proboscis Monkey is large and long. These particular types are formed as a result of muscle or cartilage development. The thumb of the foot and its toes can be held oppositely, making the hand and foot a gripping organ. The 5 fingers of the proto-monkey species can only be flexed and extended at the same time, and cannot be used individually. The palm and □ surfaces are bare, with finger and toe stripes, and the patterns are different. It has very soft or wide foot pads, and is □ except for black apes. Most species have flattened nails at the ends of the fingers and toes. In general, the length of the front and back limbs is not much different, but the forelimbs of the gibbon family and the orangutan family are much longer than the hind limbs. Apes and humans have no tail, and among the tailed species, their tail length varies greatly, from only one protrusion to more than the body length. Most species of capuchin monkeys have a gripping function on the tail, known as the "fifth hand". Some Old World monkeys (such as baboons) have brightly colored skin on their faces, buttocks, or chests, especially during the breeding season. The buttocks have hard patches of coarse skin called gluteal called gluteal calluses.
