Which is more powerful, the praying mantis or the tiger? This question does not need to be answered at all, after all, the size of the two is too much difference, and the praying mantis is not enough for the tiger to plug the teeth. But if you change the question to 200 kilograms of praying mantises, and 200 kilograms of tigers, which is more powerful? It is estimated that many people will choose praying mantises.
As we all know, the praying mantis is an insect, and the insect is a well-known "Hercules" in nature, can lift an object equivalent to dozens of times its own weight, or even hundreds of times, on this basis, the praying mantis also comes with a "double knife", but also with serrations, more outrageously, if it is a male praying mantis, it will also fly, it is entirely possible to perform a move "knife from the sky".
Such a strong mantis, just ask you if the tiger is afraid or not? So we seem to think that a 200-kilogram praying mantis should be more powerful than a 200-kilogram tiger, but is this really the case?
<h1 class="pgc-h-arrow-right" data-track="4" > 200 kg of praying mantises, can they beat 200 kg of tigers? </h1>
As far as we know, there is no 200 kg of praying mantis on the earth, so we can only assume that a praying mantis is scaled up to 200 kilograms in equal proportions, and for the convenience of calculation, we can assume that the initial weight of the praying mantis is 20 grams, and after enlarging to 200 kilograms, the weight increases by 10,000 times.
Galileo everyone knows, right? His "square-cube law" states that in the case of constant density, the surface area and size of an object are squared, and the weight and size are cubic. This law was later widely recognized and is now applied to related fields such as engineering and bioengineering.
According to the "square-cube law", we can calculate that after the mantis has increased its weight by 10,000 times, its surface area has only increased by about 464 times, and correspondingly, the cross-section of its bones and muscles has only increased by about 464 times.
This means that, when enlarged, the mantis's cross-sectional bones will bear about 22 times the body weight equivalent to their initial body size, while the muscles of the same cross-section will diminish to about 1/22 of the original.
In this way, the strength of the praying mantis will be greatly weakened, in this case, let alone flying, even the most basic movement is likely to become very difficult. But that's not all, because the mantis's oxygen supply system and blood supply system are also affected.
On each side of the mantis's body are a neatly arranged line of small holes, which are called "valves", which are specifically responsible for the exchange of gases with the outside world, and after the mantis increases its weight by 10,000 times, the volume also increases by 10,000 times, but the area of the "valve" is only increased by about 464 times, and its oxygen supply will be reduced by as much as 95% relative to the initial body size, and at the same time, the blood supply capacity of the heart muscle of the same cross-section of the mantis will also be reduced in the same proportion.
It should be noted that compared to tigers, praying mantises also have a huge disadvantage: the nerve conduction speed is too slow.
The tiger's nerve cell axon is wrapped in a tubular outer membrane composed of myelin, which is called the "myelin sheath", generally speaking, only vertebrates and some copepods have a "myelin sheath", which has an important function, that is, it can accelerate the transmission of action potentials through a mechanism called "jumping conduction", which is colloquially speaking, "myelin sheath" can make nerve signals conduct at a higher speed.
Research data show that mammals with "myelin sheaths" like tigers can reach a nerve conduction rate of 100 m/s, while arthropods without "myelin sheaths" like praying mantises have a nerve conduction rate of only about 1 m/s.
It can be seen that the nerve conduction speed of the praying mantis is much slower than that of the tiger, but because the mantis is small, this speed is enough, but for a 200-kilogram giant praying mantis, this is a huge disadvantage. To take a less appropriate example, it's like when you play a competitive online game, your "ping value" is 1000, and someone else's "ping value" is only 10, so what else to play?
<h1 class="pgc-h-arrow-right" data-track="18" > conclusion</h1>
In summary, a mantis whose weight is enlarged to 200 kilograms in equal proportions simply cannot defeat the tiger, in fact, whether such a huge mantis can survive is enough to choke, taking a step back, even if you ignore the impact of huge weight on strength, oxygen supply, blood supply, etc., it is far less flexible than tigers.
So it can be said that if you want to ask the 200 kg mantis or the 200 kg tiger which is more powerful? The answer, of course, is tiger, what do you think?
Well, today we will talk about this first, welcome to pay attention to us, we will see you next time.
