Monkey and Xiaobai's Day

Appearance characteristics of small monkeys: weight 1.5~50kg. The snout is prominent, the two jaws are strong, there are 32 teeth, the nostrils are facing forward and close to each other, the hands and feet have five fingers and toes, and the nails are flat, which can stand upright.

Some characteristics of monkey species are similar. For example, many New World monkeys have curly tails, which can be used to grasp branches when they climb trees. On the contrary, Old World monkeys do not have curly tails, but have smaller nostrils. The distance between nostrils is also close. Some of the back has hard skin, just like an embedded seat cushion.

Extended data:

monkey. It is a member of three species of anthropoid primates. The primates are a group of animal kingdom. Monkeys generally have developed brains, their orbits are facing forward, the orbital space is narrow, the toes (fingers) of hands and feet are separated, and their thumbs are flexible. Most of them can be compared with other protomonkeys and apes.

Monkeys are of medium size, with equal limbs or slightly longer hind limbs, long or short tails, cheek pouches and callose arms, and arboreal or terrestrial life, which are common features of monkeys. Most skulls of monkeys have large cranial cavities, which are spherical.

This is due to the shortening of the jaw and flattening of the face; The posterior orbital process develops to form a bone ring or a completely closed eye socket. Most species have short noses, and their olfaction is inferior to that of vision, touch and hearing. Some lower species have highly developed olfactory centers in the brain, and act on olfaction to a large extent.
