Why do flies always lie on their stomachs instead of lying there when they die?

The center of gravity of the fly's body is on the back, and after the fly is killed by the medicine, their four legs are not bent, but a pinch of them form a cone, and the body becomes a livid body, so the center of gravity is on the back of the body like a tumbler, so it will have its belly facing the sky. The body structure of flies is very special, several of their long legs are grown in front of the body, these legs are relatively slender, and most of the organs of the fly are concentrated behind the legs, these organs occupy most of the weight of the fly's body, theoretically speaking, the center of gravity of the fly is close to the back away from the front feet, so it is easier to see the corpse of the fly after the death of the fly is on the ground on the back, turning over the phenomenon.

Because the center of gravity of the fly's body is on the back, after being killed by the insecticide, their four legs are not bent, but a pinch of them form a cone, and the body becomes a livid, because the center of gravity is on the back of the body, like a tumbler, so the legs are facing upward.

Because flies are heavy on their upper bodies, their brains cannot maintain balance after death, and they will naturally turn their bellies upside down due to gravity.

The center of gravity of the fly is on the body, because of the fly's feet, the center of gravity is higher and more unstable when lying on the stomach, so the fly does not die on the stomach.

Because the legs of flies are very thin, they can support their bodies when they are alive, but they can't keep their balance after they die, so they naturally turn over.

Because flies have their own stubbornness, they feel that they have no face to die on their stomachs, so they will face the sky on their backs after death.

We know that if we stand up, we will be affected by gravity on the one hand, and disturbance in the air will disturb our balance on the other. The main reason why people can fight safely is because our bones help us resist gravity on the one hand, and our muscles help us maintain balance on the other. Therefore, there is a spontaneous use in living organisms to help them fight against various forces from the outside world to bring them to a state of self-equilibrium.

This will not only help them to carry out their normal lives, but also allow them to be in a relatively safe state. <>

In fact, if we are careful, we can find that if we see dead fish in the pond, they are floating on their stomachs. And when the fish swim in the water, they are upright. Why is this happening?

The main reason is that when the fish is alive, the muscles in the body will help him swim in the water in a more efficient way. At the same time, when the fish breathes in the water, the oxygen is more concentrated in the upper part, which causes the lower part to be heavy, so it will stand up. <>

Creatures such as flies, mosquitoes or cockroaches are always facing the sky on their backs. The reason is actually simpler, we can see that their legs are very slender. While they are alive, they can also use these slender legs to crawl while supporting their bodies.

But once they are lost, the brain no longer gives orders, and these legs lose their function. <>

A body with more mass under gravity causes them to roll over, causing them to have their legs up and their back down. In fact, this is a very normal physical phenomenon. Any creature can be affected like this, and of course if you use a sticker paper to stick to the mosquito's leg, then it will die standing on it.

Of course, there are some exceptions in nature, that is, those reptiles that are relatively low, after death, they do not lie there on all fours, but lie quietly.

Mainly because the mass of insects such as flies is mostly concentrated in the abdomen, and the mass of their limbs is basically negligible, so after poisoning, they stagger, lose their balance, and it is easier for them to face the sky when they are dying.

Because of gravity, the density of flies' backs is relatively large and heavy, so when they are killed by insecticides, they are facing the ground with their backs facing the ground.
