In 2019, China News Network reported a laughable news that said that a large python about 3 meters long in Yunnan secretly ran into the cage that villagers in Menglun Town put in the water to catch fish to "steal food".
It is estimated that there are a lot of fish in the fishing net box at this time, so the python is probably thinking about the fish in the fishing net box "one nest", but he didn't expect that he ate too much and couldn't get out of it.
The villagers found that a python had entered their fishing net box, so they quickly called the police, and soon the staff of the Natural Resources Public Security Bureau arrived at the scene and took the "accident-inducing" snake away.
According to the staff, the python was too greedy, so stealing fish consumed a lot of physical strength, and the food was too strong to stalemate, so it was trapped in the fishing net and couldn't move.
The python is about 3 meters long and weighs about 30 pounds, so it seems to be relatively healthy, so the staff kept it by its side and fed it for two days, and after determining that the python met the conditions for release, it was taken to Menglun National Nature Reserve for release.
This reserve is inaccessible, and it is estimated that this big python has no way to run to the places where people live to "steal".
Pythons are no strangers to everyone and generally feed on a variety of mammals, some of which are large crocodiles, and are one of the top predators in some tropical regions.
Although pythons can swim, they are not aquatic animals in nature, so many people think that pythons should not like to eat fish.
But in fact, this is not the case, the python does not refuse anything it thinks can be eaten, not only can they go down to the river to catch fish to eat, but they can also "wait for the rabbit" on the shore, stirring the fish nest, and when the fish is frightened and jumping, they can easily hunt.
So how do snakes manage to fish easily underwater?
«—[Fishing master who can hold his breath·]—»
The snake breathes through its lungs, which act like a long air sac that controls the snake's settling in the water like a fish bladder.
In addition, there is a special air sac under the snake's throat, which can store a certain amount of air, and when the snake dives, these air sacs will send air to the snake's lungs, which can temporarily meet the snake's oxygen needs underwater.
Therefore, snake diving naturally has a time limit, and the python that generally lives on land holds its breath for about half an hour, but this is enough for it to fish.
The python's most important weapon for fishing is its tongue, and this snake letter is not only useful on land, but also in the water.
As we all know, fish have a lot of mucus on their bodies, so when they swim in the water, the mucus on their bodies will also leave a very subtle smell, because pythons are very sensitive to smells, so it can not only detect the location of fish, but also lock on to prey more accurately even in flowing water.
Once the target has been chosen, the python will wait for the opportunity to strike quickly, biting the locked fish in one bite, and then using the "death coil" to immobilize the fish.
In this way, it is not easy for the slippery fish to escape.
Then the python will take a comfortable position and swallow the fish raw.
This is a bit surprising, because pythons breathe through their lungs, and their trachea is also open to the outside, so it is easy to suffocate when eating underwater, because the water is pressurized, and it is inevitable that it will choke into the trachea.
But this is not a problem for pythons, whose trachea has very special muscles that can "shut it off", so it is easy to eat underwater.
Of course, there are some snakes that will squat on the shore and "wait for the rabbit" to catch fish to eat, they raise their heads, their tongues occasionally stick out to test the taste of the air, and some frightened fish in the fish nest will jump out of the water, then the snake will "quick eyes" to bite the fish, and quickly swallow it into the belly.
Of course, it is possible that the fish is not dead at this time, so it will struggle frantically, so sometimes people will also take pictures of the snake's head shaking violently because of eating the fish, which looks a bit funny.
Therefore, not all snakes like to enjoy their prey underwater, and some of the more intelligent water snakes will quickly take the fish back to the shore after catching the fish, and will swallow the fish after it is completely out of the water.
This trick is more clever, after all, it will be more difficult for the fish to slip away.
But snakes have always had a big appetite, and it is not easy to make a living outside, and they often eat the last meal without the next meal, so when they encounter food, the snake will choose to eat everything they can eat.
Therefore, the python that gets into the fishing net and steals food will accidentally eat it, and finally cause itself to be trapped and unable to get out.
Naturally, some water snakes will go down to the river again to catch fish after going ashore to eat the fish, if they catch a fish in shallow water, the snake will choose to swallow the fish directly, and then swim to the shore in deep water.
Of course, snakes will also prey on fish that look much larger than themselves, but in this case, the violent struggle of the fish will also make the water snake very guilty, because most water snakes are non-venomous, so there is no way to poison the fish in the first place.
Moreover, the water snake does not have the large body of a python, so even if it is "dead entangled", it will take a long time to bite the fish tightly until it is exhausted and gives up struggling.
This is a job that requires stamina and physical strength, so it is not easy for the water snake to eat a meal, and when the fish gives up struggling, the water snake will choose a suitable angle to swallow the fish, if the fish is relatively large, it is likely that this process will take half an hour.
So if you can catch a smaller fish, it will be better for the water snake.
Of course, there is also a snake that specializes in eating aquatic creatures such as fish and shrimp, called the fishing snake, and the scientific name is "arrownose water snake".
The head of this snake has a pair of antennae similar to catfish whiskers, which are covered with tiny scales, and the fishing snake spreads part of the optic nerve and maxillary nerve into the antennae, making the antennae very sensitive.
In addition, fishing snakes will also use these two whiskers to lure small fish and shrimp when they are lurking in the water.
Its tail can hold its body in the water, and long-term "fishing training" allows the fishing snake to interfere with its prey, so that it can predict the next behavior of its prey and easily catch the "good meal".
And it also poses in a J-shaped posture when fishing, which is thought to be a certain range of its circle, because the prey will only hunt after the fishing snake enters this range, and the speed of its mouth is only a few hundredths of a second.
What's even more amazing is that after predicting the next behavior of the prey, it does not chase after the gift, but moves its head to the direction where the fish is about to flee, so that the fish can automatically "deliver to the door", saving time and effort.
The fishing snake is a slightly venomous snake, its poison can numb the prey, but it is not very harmful to humans.
In this way, snakes also have a "soft spot" for fish creatures, and even terrestrial snakes can't help but try such delicacies.
