It is said that crocodiles shed tears when they eat food, so is it really because crocodiles are sad

Of course, it's not because it's sad, it's just a natural physiological phenomenon produced by crocodiles preying on their prey. First of all, the salt content in the body of the crocodile increases when it hunts its prey, and the crocodile does not excrete it through sweat or urine like humans, and its kidney function and excretory function have basically deteriorated. Therefore, the tear glands next to the eyes can only be used to remove excess salt from the body, and the tears that come out are actually just salt water.

Secondly, the crocodile not only sheds tears when hunting, it also often secretes tears to protect its instantaneous membrane. The transient membrane can protect the eyes of the crocodile when swimming, and it is a big killer for the crocodile to maintain its vision underwater and observe its prey. Therefore, when the membrane dries on the surface of the water, the crocodile will also secrete some tears to keep the membrane moist.

In fact, in addition to crocodiles, there are also many marine creatures that use this method to excrete excess salt from their bodies, and sea turtles are the same as crocodiles, and they also shed tears due to the lack of sweat glands and imperfect excretion function.

In short, crocodile tears are simply related to its physiological structure, not because of the prey and guilt, which is simply nonsense. In nature, the survival of the fittest is always an immutable rule, and crocodile hunting is like a lion hunting an antelope is a natural food chain. Just like we humans don't cry when we kill pigs to eat meat, so crocodiles don't have similar emotions.

We now often use "crocodile tears" to describe someone as hypocritical and pretentious, a hypocrite behind the surface, and this description is indeed quite vivid, after all, crocodile looks tearful and sad when hunting, but in fact, it is just an emotionless killer.

The crocodile sheds tears when eating food, which means that the crocodile wants to remove some salt from the body, not that he will really be sad and cry after eating the food.

It wasn't tears, but the crocodile touched the tear ducts next to its eyes when it was eating, so people thought they were tears.

Crocodiles don't cry, it's just a physiological phenomenon that they cry, not to mention that the food is delicious and moved to tears.

This is related to the crocodile's own structure, and when the crocodile eats food, it will touch the crocodile's tear ducts, so it will cry.

It's definitely not because it's sad, how can a crocodile be sad, it's because the corners of the eyes secrete some fluid when eating.

In fact, crocodiles don't shed tears, and when crocodiles produce what we think are tears, they are actually covering up their next attack, so don't believe them.

Probably not, crocodiles don't have the rich feelings of our human beings, and they certainly won't be moved to tears.

Crocodiles don't shed tears, crocodiles only secrete some substances such as water in their bodies through their eyes.

Do crocodiles keep tears when they eat? I don't think so, I haven't heard of the animal world on TV. This should be a reflection.

Crocodiles are absolutely not sad, this is a physiological phenomenon unique to crocodiles, so how can cruel animals be sad?

Why do crocodiles shed tears when they eat their prey? After reading the knowledge!

The crocodile's tears are not actually because of sympathy, nor because they have feelings, but they are just a physiological manifestation of the crocodile. In fact, crocodiles shedding tears when eating prey is just a very normal way to excrete salt, not because crocodiles have the same feelings as humans. For crocodiles, tears are not crying, but they are the same as human sweat, except that their sweat is expelled from the eyes.

When a crocodile eats, a lot of salt appears in its body, because the body of the prey contains a lot of salt. If this part of the salt is not excluded, it is very bad for the crocodile's body. Therefore, when the crocodile eats, it will expel all the excess salt in the body by shedding tears.

This is equivalent to the process of the crocodile eating while expelling the excess waste from its prey.

The crocodile has a salt gland near the eyes, which is similar to the human sweat gland, and the tears that come out are actually very salty water, just to expel the excess salt, so that the crocodile's body can maintain a healthy state. It's like if a human doesn't sweat for a long time, he will feel uncomfortable.

In fact, in addition to crocodiles, there are many animal bodies that have glands that excrete salt, because these creatures living in seawater, the salt content in seawater is already very high, although they can convert seawater into fresh water to absorb, but the remaining salt after conversion still needs to be excreted, so it will be carried out by tears.

The crocodile sheds tears only because its salt glands are right next to the eyes, and if it were on the top of the **, it wouldn't be like that. Therefore, the tears of the animal kingdom are actually not the same as the tears of humans, human tears are shed because of sadness and sadness, but animal tears are a very simple and intuitive physiological reaction, and there is no connection with emotions, so don't imagine crocodiles as gentle animals, that's not!

Why do crocodiles shed tears when they eat their prey? After reading the knowledge!

First of all, crocodiles, a cold-blooded animal, do not shed tears, tears because the food they eat is too delicious, too excited, and they will burst into tears if they haven't eaten it for a long time.

Scientists found that crocodiles shed tears when they ate, and then someone asked if the crocodile was sad, and then some scientists sent the eggs laid by the crocodile to the crocodile's mouth, and the crocodile would still eat it.

Crocodile tears are a salt solution, and tearing is the excess salt that the crocodile wants to expel from its body, and the discharge tubes are just distributed around the eyes, which looks like tears.

The crocodile weeps because it wants to expel salt, not purely sympathetic to its prey, because the salt content of the sea is high, and the crocodile will cry in order to expel the excess salt from the body.

When the crocodile eats food, it will ingest sodium ions in the food, and will put the sodium ions in its body in an unbalanced state, and excrete these sodium ions through the eyes.

Crocodile tearing is a natural physiological phenomenon in which the purpose of tearing is to excrete excess salt in the body. In the middle of the crocodile's salt gland is a duct, which is intertwined with the blood vessels, separating and precipitating the excess salt in the blood, and excreting it through the ** duct. Whereas the catheter opening is near the eye.

So when these salts are separated and precipitated, it's as if the crocodile is really crying.

In fact, it is a physiological phenomenon of crocodiles. The purpose of their tears is to excrete excess salt from the body. Because the crocodile's kidney function is incomplete, it cannot remove all the salt from the body by the kidney alone, so it is excreted by other means.
