What is the relationship between monkeys and creatures whose faces look like monkeys that American photographer Mooney saw at the bottom of the sea?

Monkeys. It is one of three kinds of apes. Primates are a group in the animal kingdom. Monkeys generally have developed brains, narrow orbital spacing, feet and toes (fingers) separated, and flexible thumbs. Most of them can be compared with other primitive monkeys and apes.

Monkeys do not form a "natural group", and there are 262 known species of monkeys. In addition, because apes are similar to monkeys, chimpanzees and gibbons are often called monkeys informally, but biologists don't think they are monkeys. This is different from the appearance differences caused by different types. Monkeys have no distinctive features, because their features are all derived from apes and apes.

Some characteristics of monkey species are similar. For example, many New World monkeys have curly tails, which can be used to catch branches when they climb trees. On the contrary, monkeys in the old world did not have curly tails, but their nostrils were smaller and the distance between them was very close. Some have hard skin on their backs, just like embedded cushions. Some people also have trichromatic vision like humans; Others are bicolor or monochrome. Although monkeys in the old and new worlds have forward eyes like apes, their faces are different; Moreover, each kind of monkey has certain characteristics, such as the type of nose, chin and buttocks. Therefore, if you want to understand monkeys, you must understand their individual characteristics.

Monkey is a common name, and many animals in primates are called monkeys. [ 1]? It is an order of mammals, belonging to the highest group in the animal kingdom, with developed brains, including protomonkeys and apes. Protomonkey suborder has a fox-like face; No cheek pouch and buttock callus; Forelimbs are shorter than hind limbs; The thumb and big toe are developed and can be opposite to other fingers (toes); The tail can be curled or missing.

Ape suborder has a human face; Most of them have cheek pouches and hip calluses; Forelimbs are mostly longer than hind limbs; Degeneration of big toe; Tails are long, some can be curled, and some have no tails. According to the geographical distribution or nostril structure, the suborder simian is divided into wide-nosed monkeys, also known as new world monkeys; Narrow-nosed monkeys, also known as old world monkeys. The order includes 1 1 family, about 5 1 genus and 180 species, which are mainly distributed in warm areas of Asia, Africa and America, and most of them live in forest areas. The largest primate is a gorilla, weighing 275 kilograms, and the smallest is a bonobo, weighing only 70 grams. The skull characteristics of the tree family are very similar to those of some primitive monkeys. Many anatomists and paleontologists have listed it as a primate, but its external morphology and ecological habits are very different from those of primates. Therefore, modern taxonomists have classified it as a tree order independently.
