It only takes a few data to let everyone know what kind of river it is: its runoff is 7 times that of the Yangtze River and 123 times that of the Yellow River, accounting for 10% of the world's river flow into the sea. 20, the basin area accounts for 40% of South America!

What’s even more amazing is that the Amazon River Basin forms the Amazon Hot Forest, which is also the largest tropical rainforest in the world. It is a paradise for animals and plants, but it does not welcome humans, especially the Amazon River. There is not even a river on it. No, you have to find a place to swim, and you have to be fully equipped to get into the water!

What is there in the Amazon that is so difficult to swim in?

There is really no bridge on the Amazon River. The bridge you think of as the Negro River is actually on the Negro River, a tributary of the Amazon. The difference between the rainy season and the dry season of the Amazon River is really big, so for Brazilians For me, the cost was unacceptably high, so I settled for the next best thing and decided to take a boat ferry!

The mouth of the Amazon River is like the sea

There are really too many threats from the Amazon River underwater. The ones that can be mentioned are the threats that everyone knows:

1. Amazon Black Caiman

2. Amazon Piranha

I don’t need to mention the threat of the crocodile. Its signature move is to rush up and bite. Hold a certain part, such as a hand or foot, and then spin it in the water to directly break the part you bite. Because the crocodile's teeth are only used to bite prey, cutting is not its function, so the crocodile is not tearing food. Just twist it and break it, and the wound caused by this method is very difficult to treat!

And the black caiman is huge, with a total length of 1.9-5 meters and a weight of 200-500 kilograms. It is also the largest carnivore in the flax basin, and its record is extremely bad, because it has many attacks, There are records of human predation. In the Amazon Basin, if you are attacked by a black caiman, it will definitely be a disaster.

The piranha may be more dangerous than the black caiman, and its cruelty is outrageous! The piranha's wind-powered incisors can bite its prey to pieces, leaving only white bones behind.

Although there are many kinds of piranhas, there is only one threat, and as long as it attacks humans, it is the piranha! There are duels between piranhas and black fish and other fish on various short video platforms, and the final result is often eaten into bones! Of course, it is not limited to short video platforms. Piranhas play important roles in many Hollywood blockbusters!

Piranhas are small in size, generally around 14 to 26 centimeters. Their unique tooth arrangement is easy to identify. The teeth of all piranhas are tightly arranged in a single layer and fixed on the upper and lower frontal bones. , cross each other, and it is very easy to cut off the prey's body.

However, scientists have pointed out that piranhas are actually very timid. When they are alone, they are often attacked by cormorants, caimans, electric eels and puffer fish. However, when in groups, they are extremely aggressive and can It gets progressively crazier, which makes this species even more daunting.

Another fact to note is that the red-bellied piranha is often raised as an ornamental fish in aquariums, and some people will release it because of the outbreak of the Virgin Heart. In July 2012, the media reported According to reports, a piranha attack occurred near the Liujiang River in Liuzhou, Guangxi. However, what can reassure everyone is that this fish cannot survive the winter in the Liuzhou area.

Amazon toothpick fish

This fish is very small, about the same size as the whitebait in whitebait custard, or even smaller! You must not think that it is careless since it is young. This kind of fish has a famous nickname: "JJ fish". I believe you can understand the meaning of this term. Of course, it is not only a threat to men's penis, but also to women. Need special attention!

One thing it particularly likes to do is to swim upstream along the current, so when you pee in the water it sneaks in. Women shouldn’t be complacent, because this method is the same. Suitable for women, and women's passages are looser than men's, so the threat may be greater!

So when you swim in the Amazon, you must not only prevent piranhas, but also toothpick fish. Wear tight boxer shorts on the boat and don’t pee, and you’ll be fine!

Amazon Electric Eel

Another fatal threat in the Amazon River is the electric eel. In fact, the Amazon electric eel cannot kill people with electric shock, but it does not need to electrocute people. It only needs to stun people. The river will do the rest. If you are stunned in the water, without help from others, you are definitely dead!

The muscles on both sides of the tail of the Amazon electric eel are very special. It is composed of a structure isolated from thin muscles and connective tissue, and has nerves and central nervous connections. These small muscles can generate a voltage of 150 millivolts. Looks low doesn't it? But the number of these muscle slices is as high as 6,000 to 10,000. Can you calculate how high the voltage will be after being connected in series?

If you calculate the loss, it is about 300-800V, which is similar to the voltage used by electric fishmen (some are higher). The electric eel can be up to 2.5 meters long and weighs 20 kilograms. A sustained discharge is enough to kill a person, so encountering it is a very dangerous thing.

The unlucky crocodile bit an electric eel and was stunned

Amazon green anaconda

The largest snake on earth is the green anaconda. The protagonist of "Anaconda", the largest green anaconda is about 8 meters long and weighs about 160 kilograms. It is not poisonous, but it can easily kill and swallow a person, so it does not need fangs at all!

And it usually lurks in swamps full of aquatic plants, dormant quietly under the water, a very threatening and hidden top predator!

In addition to the above-mentioned terrifying animals, some friends believe that the Amazon giant otter, arapaima and giant otters are also the biggest threats, but these three species do not seem to have any records of attacking people, while the arapaima They are known as idiots and are almost extinct!
