<> "The Most Dangerous Fish in the Amazon Rivers.

This notorious little fish in the Amazon basin is called "parasitic catfish", but most people prefer to call it "toothpick fish", and some even call it "fish from hell", "Brazilian vampire fish", and most of these people are victims.

The toothpick fish is a parasitic fish and may be the smallest vertebrate in the world, generally within 10 centimeters in size, and its whole body is almost transparent, so it is extremely difficult to find in the water.

Toothpick fish have a very strong swimming ability and can swim quickly in the water, after all, the water of the Amazon River is full of dangers, and if you don't swim faster, it is easy to be "big fish eat small fish".

The toothpick fish, which swims very fast, realizes "small fish eat big fish", and the toothpick fish is just like its name "parasitic catfish" is an animal that lives by parasitism, and the toothpick fish will burrow into the gills of the big fish, rely on its gills with barb-like spines, fix itself in the gills of the big fish, and then suck the blood of the fish in the gills of the big fish.

When a man enters the river, the toothpick fish will inadvertently drill into the human body along the man's urethra, and then cut through the person's internal ** bleeding to suck the blood, this process is naturally needless to say, it is simply torture for people, so it is called "fish from hell". After sucking blood and eating enough, its body will swell, and under normal circumstances, it will choose to swim away, but the toothpick fish that swells in the human body has no way to exit, and can only go all the way forward and finally come to the bladder.

In the old days when there were no leggings, people were very vulnerable to these small fish in the Amazon rivers, and medical technology was not developed in those days, and many people were able to cut off some of the necessary organs in exchange for their lives after being drilled into the body by toothpick fish. Once the toothpick fish enters the bladder, the host is faced with endless abdominal pain, which is painful, and finally dies due to excessive blood loss.

Therefore, most of the local people are afraid to avoid this "toothpick fish trembling bird".

The largest fish in the Amazon is the arapaima.

Since the length of the river is inconclusive, there are many different versions of the length of the Amazon, one of which is the common 6,400 km.

The Amazon River is the second longest river in the world and the world's largest river, with a flow of 10,000 cubic meters per second, which is several times larger than the combined flow of the other three major rivers, the Nile (Africa), the Yangtze River (China), and the Mississippi River (the United States), which is about equivalent to the flow of seven Yangtze rivers, accounting for 20% of the world's river flow; The basin covers an area of 10,000 square kilometers, accounting for 40% of the total area of South America; The number of tributaries is more than 10,000.

This is inseparable from its unique natural environment. The Amazon River is one of the world's great rivers, it originates from the Peruvian Andes, passes through the vast rootless Amazon plain in the east, and enters the Atlantic Ocean on the island of Marajo, Brazil, with a total length of 6,400 kilometers. There are more than 20 tributaries of more than 1,000 kilometers in the entire water system, with a basin area of 7.05 million square kilometers, accounting for almost 40% of the South American continent and four times the size of the Yangtze River basin in China.

This large river flows mainly through rainy areas near the equator and has an abundance of water all year round, making it the world's largest river basin and largest volume.

The geographical location and water system characteristics of the Amazon River provide excellent environmental conditions for the biological world, along both sides of the water system, the forest is lush and empty, the climate is humid and changeable, the soil is rich in nutrients, and the hydrological conditions are suitable, all of which provide a stage for freshwater fish to reproduce and survive. When you add to this the development of natural history, it is not surprising that the Amazon River is the most fished river in the world. Big rivers produce big fish, this is a general rule.

It is the second largest river in the world. The Amazon River pumps 10,000 cubic meters of water into the Atlantic Ocean every second, about three times more than the Say, 10 times more than the Mississippi, 60 times more than the Nile, and accounts for 20% of the world's total river flow. The water is abundant and powerful, and the fresh water of the estuary rushes into the Atlantic Ocean for up to 160 kilometers.

Among the tributaries, 7 are more than 1,600 kilometers long; The longest is the Madeira River, which is more than 3,200 kilometers long.

The water volume is abundant all year round, with an average annual flow of 220,000 cubic meters per second in the estuary, and a flow of more than 280,000 cubic meters per second during the flood season, making it the river with the widest area and the largest volume of water in the world. The mountains in the Shangyuan area are high and the valleys are deep, the slopes are steep and the flow is rapid, and the average ratio is about the same. After entering the plain, the specific drop is small. ‍‍
