And the rich man in Gao Shuai in the picture is actually peacock mantis shrimp? Mantis? Shrimp), also known as mantis shrimp, belongs to the class Dentopoda, while Pippi shrimp generally refers to the class Dentopoda.

The Truth about Peacock mantis shrimp? ↓? It belongs to the crustacean of freshwater shrimp.

2. Can mantis shrimp really see so many colors? (It may be as squeaky as their shells. )

Mantis shrimp does carry 16 color cones, which can sense infrared light, ultraviolet light and polarized light.

First, popularize a word called color vision (color? Vision), based on the wavelength of light reflected, emitted or transmitted by organisms or machines? (or frequency)? To distinguish objects. Color can be measured and quantified in different ways; In fact, people's perception of color is a subjective process, that is, the brain responds to the stimulation generated when the incident light interacts with several cone cells in the eye.

The formation of human vision can not be separated from visual cells, among which rod cells are used to feel weak light, and cone cells can feel daytime light and color. Humans have cones, and they can feel the three primary colors of red, green and blue. The colorful world we see is embodied by these three colors.

However, some animals have more kinds of cells that can perceive colors than humans. For example, birds can sense ultraviolet rays, and a mantis shrimp in the sea carries 16 kinds of cone cells that can sense infrared rays, ultraviolet rays and polarized light.

So birds and mantis shrimp can see a brighter world than humans, which we can't experience.

Dogs' visual cells are not as good as people's, and the world in their eyes is black and white. The world seen by cats is black and white with blue and green.

Most herbivores in mammals have average vision, basic color blindness and no stereoscopic vision. ?

Most carnivores have good eyesight and stereoscopic vision, but they are basically color blind. ?

Most primates have good eyesight, stereoscopic vision and can distinguish colors. ?

Most birds have good eyesight, stereoscopic vision, strong ability to distinguish colors, and the function of double adjustment of focal length. ?

Reptiles, amphibians and fish have poor eyesight, and most of them are color blind. ?

Among invertebrates, octopus and squid have better eyesight and are close to higher vertebrates. ?

Others, such as insects, have poor eyesight and can only distinguish objects at close range. But it reacts quickly to moving objects.

Take a few animals as examples:

M: I can't see the middle part between my eyes.

Snakes: infrared perception

Cats and dogs: night vision.

Bird: You can see at least five spectral bands.

This is the world they see.

Therefore, mantis shrimp, who has the most complex color vision, sees a brighter world than the bird pictures above. (brain-strengthening bar)

3. Is mantis shrimp really that capable of attacking? You can even break through the aquarium?

Squid widely lives in the waters around Taiwan Province Province, and its second pair of jaws and feet are specialized into a pair of huge aggressive appendages with strong muscles. According to the differences in the shapes of specialized appendages, squid can be divided into two types: puncture type and crushing type.

In our diving, it is common that the green fingered shrimp belongs to the crushing type. Just like a super heavyweight boxer, crushed squid can easily crush the hard calcareous shells of shellfish and snails. A fully-grown fingered squid can punch as hard as a.22 pistol bullet, and even the glass of the strengthened fish tank can't stand his blow.

Therefore, not all mantis shrimp are so majestic. The cartoon should describe the crushed shrimp, but the punctured shrimp is not so powerful!
