Mantis shrimp is of great value, and it is the collection object of Zu Hai Pavilion. In an ornamental fish tank, the bright colors are very eye-catching. But it's a pity that mantis shrimp, who can eat by her face value, has no consciousness of making a vase at all. She will break 6mm glass with one punch and escape from the glass jar. Disdaining to eat by the value of face, mantis shrimp used his own pair of iron fists to conquer the world. Crab, clam, conch, even the thick back shell, all hard shells can be broken by mantis shrimp. In the shallow rock area where it lives, there is no food that mantis shrimp can't eat.
How powerful is the iron fist that breaks glass and hard shell? The maximum acceleration of mantis shrimp's punch can reach 104km/s 2, and the speed can reach110 km/h. He hits the hard shell of his prey with a weight of 72kg. The power is equivalent to shooting 0.22 caliber bullets (small caliber pistols).
Mantis shrimp is the fastest boxer in the animal kingdom, and his explosive power can easily break the defensive armor of other crustaceans. So is it invincible in the sea, and no one can resist its fist? No, it is surrounded by a close opponent, and it is another kind of mantis shrimp that can compete with mantis shrimp.
Mantis shrimp has not only the fastest fist, but also the strongest armor. Two mantis shrimp confrontation, fist helpless armor. The spear of the son, the shield of the attack and the shield of mantis shrimp are not inferior to their spears. Its iron fist and armor are more impact-resistant than the aircraft shell and tougher than bulletproof materials.
Mantis shrimp's iron fist
Mantis shrimp is not a shrimp, it is a shrimp, and it is the familiar Pippi shrimp. There are 500 species of mantis shrimp living in rocks and caves in shallow water. In mantis shrimp, fish eat meat, and the front ends of prey feet (second jaw feet) have weapons. Like mantis, it usually folds its hoe-shaped prey feet on its chest and pops up when it attacks. There are two kinds of feet, one is that the front end of the foot is like a spear, which is used to stab fish. The other is like a pair of wooden sticks at the front end of the foot, which are used to break the hard shell. In the ethnic group, there are more puncture players than punch players (also called crush players).
You can clearly see that mantis shrimp has a pair of sticks and fists on his feet. He is also the fastest boxer in the group. Mantis shrimp is very small, just a little longer than his fingers, with an average length of 6 ~ 12 cm.
Mantis shrimp is a small man with a big temper. He didn't agree, so he picked up an iron fist and hit you. Don't underestimate the boxer. Mantis shrimp's punches don't just rely on brute force. It not only accumulates energy, but also detonates water waves, adding multiple levels of strength to his punches.
Mantis shrimp's feet are very elastic and can accumulate strength like a spring. The orange arrow in the above picture marks the spring area where it accumulates strength, contracts the leg muscles, compresses the spring, and instantly releases the attack after pressing to the extreme. The attack speed of accumulating strength is much faster than that of simply relying on muscle drive. The spring leg can be stored for 700 microseconds, but it only takes 2 microseconds to release, which can release energy more than its own weight 1000 times.
The power of instantaneous eruption is not enough, and mantis shrimp will use the power of water. When mantis shrimp's wooden stick accelerates the attack, it drives the water flow to accelerate suddenly, and the surrounding water flow can't keep up with the speed water flow, resulting in vacuum cavity bubbles. The water current carries bubbles to hit the prey, and the bubbles burst instantly, adding more impact to the prey. Water explosion force is stronger than boxing force, sometimes reaching more than twice as much as boxing force.
Due to the sudden drop of water pressure, the phenomenon of gas appearing in the water flow is called cavitation. The double blow of wooden sticks and cavitation, not to mention flesh and blood fish, even thick crustaceans can't stand it. The crab walking sideways suddenly broke. An oyster that feels that the world is at peace with its shell closed was smashed in one fell swoop.
Mantis shrimp's armor.
Matching with the iron fist, it is mantis shrimp's armor.
Mantis shrimp, who lives in a coral reef, often raises his iron fist for a cave. The accomplices are fighting for territory, and there is no enmity between life and death, so the competition between them will not hurt the vital parts. Two mantis shrimp compared strength, strength to speak, strength to make way for the small. When competing for strength, one mantis shrimp bent his back and the other mantis shrimp punched the tail nail. Invincible iron fist can only make the companion feel the strength, but it can't pierce its tail armor.
The unbreakable tail of an iron fist is like a shield to resist external forces. The shield has a curved ridge protruding outward and a spiral structure like an iron fist inside. The rib can reduce the impact force, and the twisted structure of internal rotation increases the toughness of the armor.
The joint team of the University of California and Purdue University found that the external ridge and the internal spiral can not only absorb most of the kinetic energy during impact, but also prevent the crack from spreading on the shell. In addition to compression resistance, elastic armor can also bend inward to release strength, effectively protecting the internal body from injury.
In a word, mantis shrimp's armor is stronger, more elastic and more impact-resistant than that of other animals.
The spear of the child, the shield of the attack, and the iron fist are equal to the armor.
