In rivers and oceans, there is a strange fish with a special skill.

This special fish is the puffer fish, and this special skill is to bloat.

Many people must have seen the picture of puffer fish with a bloated belly.

This kind of fish is not very big, but once it encounters danger, its belly will expand rapidly. Inflate yourself into a round ball.

At the same time, some of the small spines on their belly will also stand up one by one, looking like a hedgehog.

does this to protect itself.

Because fish like pufferfish are small predators on the seabed.

In order to protect themselves, they inflate their bellies and their bodies become very large. That way, predators can't get it into their mouths.

Many people may think that the pufferfish’s belly is filled with gas, and it is the gas that inflates the belly.

In fact, this is not the case. The pufferfish’s belly is not inflated by gas, but by drinking water desperately.

As long as the puffy puffer fish opens its mouth, streams of water will spurt out from its mouth, and its belly will become flat accordingly.

In fact, we have seen some videos on the Internet of puffer fish with bulging bellies. The reason is not that they are holding their breath, but because the puffer fish is desperately drinking water.

Researchers once studied the secret of the pufferfish's bulging belly. They found that the pufferfish under attack will quickly increase its size by absorbing water, and then let its belly bulge.

The bulging belly can immediately make the fish that come to prey on it give up the prey in its mouth.

Because its belly is bulging, it is too big for them to swallow.

When the puffer fish bulges its belly, it will still breathe through its gills as usual, but the breathing rate will increase several times.

But if it is actually on the shore, the puffer fish can only rely on holding its breath to bulge its belly.

If the puffer fish expands its belly, will it cause any harm to its body?

Many people may see this message saying that the pufferfish's belly can only be inflated three times in its life, and after three times, the pufferfish will die.

There is another saying that it can only be inflated six times. After six times, the pufferfish will be in a dying stage due to the relaxation of its belly.

This statement is actually incorrect.

The puffer fish's abdominal skin is very loose and densely covered with small spines.

Only when in danger, puffer fish will quickly bulge their belly.

But this kind of belly-bulging behavior is just a means of self-defense. It is like the roar of tigers and lions when they encounter danger. It is like the cuttlefish that sprays ink when it encounters danger. It is like the skunk when it encounters danger. biological weapons will be released.

This is a defensive method evolved by animals in nature, and there is no so-called limit on the number of times this method can be used.

If a pufferfish can only bulge its belly three times in its life, will it bulge its belly when it encounters danger for the third time?

Even if it scares the enemy away by inflating its drums, it will die due to the limit of times.

But if it doesn't puff up, it will be eaten again.

Therefore, the pufferfish's behavior of bulging its belly is just like a cat raising its whole body when it encounters danger. It is also a biological defense inability. This instinct is the same as humans sleeping, eating and going to the toilet. , there is no so-called limit on the number of times.

Those who say that a puffer fish will die if it puffs up three times are completely untrue.

However, although the pufferfish's body expands very quickly, the recovery time after the expansion is relatively long.

Many people will hold the pufferfish in their hands to see its belly bulge, but this is a kind of harm to the pufferfish.

In addition to being able to inflate puffer fish, this fish also tastes very good.

In our country, there are many historical records about eating puffer fish.

Since ancient times, the ancients have regarded pufferfish as an excellent food ingredient.

Most of the pufferfish captured by the ancients were those found in fresh water in rivers.They discovered that this kind of fish would make a pig-like sound when they caught it, so they named it puffer fish, which means pig living in the river.

However, many people may know that pufferfish is not a simple fish.

Its body contains a very powerful toxin.

This toxin can be said to be fatal to humans.

Although puffer fish looks harmless to humans and animals, the toxins in its body are very strong.

When a person is accidentally poisoned by blowfish, the nervous system will be anesthetized within thirty minutes.

People who ingest as little as 0.5 mg of tetrodotoxin are at risk of death.

This is a highly toxic toxin. When it invades your body, it will immediately paralyze your nervous and muscular systems, your lips will feel numb, your tongue will be unable to move, and you will soon suffocate and die.

The most poisonous fish among puffer fish is the puffer fish. The toxin content in one fish can kill 33 people.

But even so, in order to taste the taste of puffer fish, some people still try their own poison and go one after another to taste the taste of this fish.

Therefore, a strange qualification certificate came into being in the chef world, called the Fugu Chef Qualification Certificate.

Only chefs with this qualification certificate are qualified to handle puffer fish meat.

A chef who does not have this qualification is likely to be poisoned after eating the pufferfish meat he handles.

Once you accidentally get poisoned by puffer fish, you can only pray that it is just your illusion.

Therefore, for the sake of your own safety, try not to eat puffer fish.
