Pippi shrimp is a common delicacy on the human table. It is a genus of shrimp in the family Shrimp Worm family, widely distributed in tropical and subtropical waters, and is produced in coastal areas of China. This common shrimp has many relatives, such as the mantis shrimp belonging to the same family of shrimp mantises, which can also be seen as a type of Pippi shrimp.
So have you ever learned about mantis shrimp? Let's talk about the past and present lives of mantis shrimp and their characteristics that are almost like "alien mechs".
Mantis shrimp first originated in the Mesozoic Era, about 252 million years ago. Hundreds of millions of years is enough to allow a species to evolve dozens of times. Just like human beings have evolved from learning to walk upright to today, it has only experienced more than a million years.
And the animals we usually see, in fact, did not look like this hundreds of millions of years ago. Whale ancestors used to live on land and are relatives of our hippopotamus today. But the Phi Phi shrimp species, from their emergence to the present, has not evolved for hundreds of millions of years. In other words, pippi shrimp 250 million years ago looked similar to today (including mantis shrimp).
We all know that species evolution is a process of adaptation to the environment. In order to adapt to changes in the living environment, organisms will more or less undergo a little evolution. For example, sharper weapons have evolved to be easy to prey on, or to evolve harder shells to protect themselves. From the perspective of software, the evolution of species is like an update of software, constantly optimizing its own updated version to obtain better living conditions.
Mantis shrimp have not evolved in the last few hundred million years because they don't need to. This small shrimp mantis, full body black technology, even at today's scientific level, mantis shrimp is still like an alien mech thrown on the earth by aliens, so strong that it can be called a living "Godzilla"!
In mammals, the human eye is also a top configuration, and we can see three colors through our eyes - "red, green and blue", that is, three primary colors. The colors we can understand are actually the colors they are mixed together. And the dogs that live around us, they can't tell the difference between red.
This means that dogs cannot brainstorm colors related to or derived from red. Humans look at the rainbow as colorful, but in the eyes of dogs, they cannot understand and distinguish the rainbow. There are also colors in nature that humans can't see, and just because humans can't see them doesn't mean other animals can't see them. For example, butterflies, they generally have 5 kinds of visual vertebral cells, can see five colors;
The mantis shrimp is more cattle, it can see 16 colors. Imagine that human beings can see the three primary colors of red, green and blue, which is enough to see such a colorful world. You can see 16 colors of Pippi shrimp, and you can imagine how gorgeous the world is in their eyes.
Moreover, the eyes of the mantis shrimp have 6 pupils, so the top configuration, you can see infrared, ultraviolet is the basic operation. You can also calculate various parameters to make your attacks accurate and elegant! Perhaps in their eyes, they can see the true color of the world.
A biologist named Sheila Pate, who studied Phi Phi shrimp, said they were the fastest "punching" creatures in the world. Later scientific research also proved that Sheila Pat's conclusions were not wrong. Inside the Phi Phi shrimp, this relative called the mantis shrimp, they can be said to be the most terrifying "boxers" in the world!
Simply put, the "boxing speed" of mantis shrimp can reach up to 80 km / h. While the data is not exaggerated, what if they accelerate from stationary to 80 km/h in less than a millisecond (1 millisecond equals 0.001 seconds)? Among them, the acceleration can no longer be said to be exaggerated, but terrifying to indescribable.
For a simple example, when a rocket made by humans lifts off, the general gravitational acceleration is 10g, and the gravitational acceleration when Pippi shrimp punches is 10000g. If humans had such a wave speed, they would be fully capable of throwing what we had in our hands directly out of the ground out of the earth!
Moreover, at extremely fast "punching" speeds, when mantis shrimp attack prey, they will produce a cavitation effect, and high-speed friction will vaporize water molecules instantaneously and produce collapse. This collapsing shock wave is enough to stun the prey.
It is said that "the iron also needs to be hard", the mantis shrimp has a very fast punching speed, and it must have a corresponding shell to withstand the mutual force generated when attacking. David Kisailus, a chemical engineer from the University of California, and his research team used a scanning electron microscope to X-rays to examine the structure of the mantis shrimp claw and found that there were complex layers of structure in it.
The outermost part of the chelat is covered with highly crystalline hydroxyapatite; below is a multilayer of hydroxyapatite, but it does not form crystals; the innermost layer is chitin (also known as chitin), a slightly soft substance arranged in a spiral, and the voids outside the spiral are filled with hydroxyapatite.
This peculiar structure has differences in hardness and arrangement, and the effect of this difference is to allow mantis shrimp to produce certain small cracks when hitting prey, but there are cracks that can effectively be organized to expand. This structure can ensure that the mantis shrimp's claws will not be damaged under 50,000 blows. Even if they are damaged, they can be repaired in the form of molting.
Creatures that communicate through light are not uncommon, but mantis shrimp communicate in a more advanced way with optical signals, thanks to their unique eyes.
We all know that the essence of light is an electromagnetic wave, which vibrates when propagating, and when the direction of vibration and the direction of propagation are different, "polarized light" will be generated. The human eye cannot see polarized light, but the eyes of mantis shrimp can, and their shells can reflect this unique light.
Therefore, the mantis shrimp will use polarized light to communicate, because humans can not see the polarized light, the lack of understanding of the communication content of the mantis shrimp. At present, the only cracked polarized light language of mantis shrimp is the polarized light reflected through the surface of the chelate when they molt, which means that the meaning is probably to convey to the companion: "You look at the gloss of the reflection of my new weapon, but it is great, you also come to try it."
postscript
There are also many black technologies on the mantis shrimp, so I will not repeat them all. Such a "open hanging" species of black technology, if the body size is a little larger, it is not impossible to become the hegemon of the sea.
Even if it is only the size of a human palm, mantis shrimp are not easy creatures in the sea. Blessed with "black technology", they are one version ahead of all species on Earth. Since it already has near-perfect physical conditions, the mantis shrimp naturally does not need to evolve in the past few hundred million years, and the axes are enough anyway.
