It is also a place rich in species and has the reputation of "the kingdom of animals and plants".
So, what kind of creatures are hidden in this mysterious area?
This is the caiman, the top creature of the Amazon ecosystem.
Cayman is related to alligators, but smaller than other crocodiles, with an average body length of only 1.2 to 1.8 meters.
They are similar in appearance to American crocodiles, with long tails, slender noses and protruding bones in the middle of their eyes.
Their diets are different. Monkeys, piranhas, deer and even pythons are all within their hunting range.
This fierce crocodile sometimes attacks humans. On 20 10, a biologist was attacked by the caiman. Fortunately, her life was not in danger, but as a "trophy", the Caiman took her leg.
The muscles in the caiman's mouth are not developed, and an adult man can control it so that it can't open its mouth, so many crocodile hunters take advantage of this weakness to catch caiman.
This is the Amazon puffer fish and the largest freshwater dolphin. There are many skin colors, from brown to white and even pink.
Their bodies are unique, they can rotate their heads and necks flexibly, and they are unique species in the Amazon basin.
Amazon puffer fish's snout is sharp and long, but the cheeks under their eyes are fat, which makes their vision under them a blind spot, but when this happens, they usually choose backstroke.
These puffer fish are very kind. They will curiously follow the passing ships and play with people.
This is the green python, also known as the green python. It is one of the largest snakes in the world. The largest green python found by people is about 8 meters long and weighs 160 kg.
They mainly inhabit the tropical jungles in the Amazon River and Orinoco River basins and feed on various mammals and reptiles.
Although the green boa constrictor is huge, it is a non-toxic snake. Like pythons, they will wrap their prey tightly until it breaks and suffocates, and then open their mouths and eat it alive.
Although the net python in Asia is longer than the boa constrictor, the green python is heavier than the net python, so even if the green python is not the longest snake, it is the heaviest snake.
This is a glass frog. Its most unique feature is that its back is gray-green from above, but from below, you will find its abdomen is translucent.
Through this translucent skin, you can clearly see their internal organs, including heart, liver and digestive tract.
Glass frogs's body is very small, only two or three centimeters, but his eyes are surprisingly big, his pupils look like a minus sign, his limbs are slender and his sucker is developed.
Glass frogs mostly lives in trees, and they only live in places with good environmental conditions. Therefore, by observing their number, we can reflect the environmental degree of this place.
However, due to the continuous land reclamation, there is less and less space left for glass frogs to inhabit, and it is listed in the Red List of Endangered Species.
There are many unique and dangerous creatures living in the Amazon basin, but even small fish may sometimes pose a threat to human beings.
This is a red piranha, a typical piranha in Amazon. Their jaws are developed, their teeth are sharp and their bellies are red, so they are called red piranhas.
Although red piranhas are dangerous, they swim very slowly. In the Amazon jungle, there are natural enemies everywhere. The high voltage current released by only one electric eel can "kill" 30 red piranhas at one time.
