The Amazon River, located in South America and originating in the Andes Mountains, is the second longest in the world, but its flow and basin area are the largest in the world, ranking first in the world. Pen, fun, pavilion www. biquge。 info

The Amazon rainforest is home to some of the world's richest and most diverse biological resources, with millions of species of insects, plants, birds and other organisms, many of which have not yet been scientifically documented.

Among the lush plants are a variety of tree species, including myrtle, laurel, palm, acacia, sandalwood, brazilian and rubber trees. Mahogany and Amazonian cedar make high-quality wood. The main wild animals are: jaguars, manatees, tapirs, red deer, capybaras and many rodents, as well as a variety of monkeys, known as the "animal and plant kingdom of the world". It is also known as the "lungs of the earth" because it covers half of the world's rainforests.

The biodiversity of this rainforest is remarkable, with 2.5 million species of insects, tens of thousands of plant species and about 2,000 species of birds and mammals, and a fifth of the world's total bird population.

Some experts estimate that there are more than 75,000 species of trees and 150,000 species of higher plants per square kilometre, including 90,000 tons of plant biomass. Scientists point out that in Brazil alone, there are about 843 species of invertebrates.

The Amazon rainforest is one of the most diverse plant species in the world, with experts estimating that 1 square kilometre may contain more than 75,000 species of trees and higher plants, and 1 square kilometre may contain 90,790 metric tons of surviving plants.

The Amazon rainforest is the largest animal and plant environment in the world, with one fifth of the world's birds living in the Amazon rainforest. At present, about one species of plant with economic and social interest has been found in the Amazon rainforest, and many more are yet to be discovered and classified.

The above data are all derived from the scientific research results of scientists in the 21st century where Wu Fei lived.

However, these data are the results of scientific research thousands of years later. Thousands of years ago, Amazon was not what it was shown in textbooks and pictures. Just like the primeval ancient forest where Wu Fei was at this time, the ancient trees inside were towering, and the decaying fallen leaves overlapped the ground.

The branches of the trees obscured the sky, and even the midday light could hardly penetrate the thick trees and penetrate the dense ancient forest. Therefore, under such years of accumulation, the interior of the ancient forest could not receive sunlight, became damp and gloomy, and the ground was full of fallen leaves.

In addition, it is located near the equator and has a tropical monsoon climate, with annual precipitation of more than 2,000 centimeters. Therefore, the ground in the ancient forest is covered with water systems extending in all directions, which in turn forms a wide range of marshland distribution. Even if there is a field, it is a very small part.

Not only that, but the primitive inhabitants of this area are also very xenophobic and vicious, and if they find a stranger intruding into their territory, they will immediately launch a fierce attack. Once they have succeeded in attacking, you don't want to leave this ancient forest alive.

Among them, there is a fish creature that lives in the Amazon River - the Paku piranha. They have distinctive, human-like teeth and are omnivorous. It not only eats aquatic plants, algae and other plants that grow in Hanoi; It also eats shellfish, fish creatures like it.

After the twentieth century, they entered some freshwater seas in Europe through some tributaries of the Amazon River basin. Some men who are a little careless will be bitten off their penis by this strange fish when swimming naked. Such a scene, let alone witnessing it in person, is very frightening even if you imagine it.

Another species of fish that is also famous, is the vampire fish, which makes people talk about tigers.

They are definitely ferocious carnivores, can grow up to 12 meters, and feed mainly on piranhas. They get their name from those two fangs. The teeth can grow up to 15 centimeters (six inches) long and are used to pierce the body of the prey. Moreover, the appearance is very ugly, just like the vampire in Western mythology and legend, hence the name vampire fish.

These are all ferocious beings that live in rivers, and as long as you don't enter the river realm, they can't do anything about you.

However, the next few things to talk about are the existence of no avoidable and no avoidance. Because they live in this dense primeval ancient forest, and they are also some very common places. Even if you deliberately avoid it, it won't help. Even the primordial overlord-level beings who live here are reluctant to provoke them if they have nothing to do.

The black caiman, which can grow up to six meters (20 feet) long, has a skull that is larger and heavier than that of a Nile crocodile and is an apex predator in the Amazon rainforest. This means that they are the overlords of the forest, eating almost everything they can eat, including piranhas, sea bass, monkeys, deer, pythons, etc., and they also attack humans. In 2010, a biologist was attacked by a black caiman on a houseboat, and although he managed to escape, he lost a leg, and the crocodile had been waiting quietly under the houseboat for 8 months, waiting for an opportunity to attack.

Most of these crocodiles are distributed in the swampy ponds scattered throughout the ancient forest, and some of them enter the river domain and become the overlord-level existence in the river.

Most of them act individually, usually lying quietly and sleeping, and very patient, once they find their prey, they will not rush to attack, but quietly wait for the right time. When the time comes, they will strike like lightning, dragging their prey into swamp pools or water with lightning speed, and tearing it apart with their sharp teeth to feed.

There is also a kind of ruthless killer that lives on the trunk - the giant python.

The giant pythons that survive in the Amazon rainforest are more common in the reticulated python and the green python, the reticulated python is longer and the green python is heavier.

Female pythons are generally larger than males and can reach up to 250 kilograms. It is nine meters long and up to 30 centimeters in diameter. Although they are not venomous snakes, they can use their powerful muscles to suffocate prey such as deer, caimans, capybaras, and even jaguar deer. They prefer to inhabit more submersible waters for better prey.

There is generally only one end to encountering them, and that is to be strangled and suffocated to death by them with their powerful muscle power.

In addition to these top existences in the animal kingdom, let's take a look at the cold-blooded overlords of the plant kingdom.

Have you ever seen a vine that breathes? On top of the huge and thick tan vines, there are oval-shaped breathing vents, one by one, closing and breathing rhythmically, as if they are really wheezing. If you think that the existence of these oval-shaped breathing ports is really vines doing aerobic respiration, you are very wrong.

They do this to get the attention of the insects. When the insects land on their breathing ports, the breathing ports that are open and closed immediately close and the insects are imprisoned and devoured in the small prison they have set up.

There is also a huge flower with a bright and shiny appearance, which is very attractive from a distance. However, any regular visitor to this ancient forest will avoid it, because, under its seductive form, there is a name that makes people talk about the tiger's color - the troll man-eating flower.

This plant is born at the top of the food chain in the plant kingdom. They generally exist in solitary form, from a small seed in their youth, to a large plant with a radius of two or three meters. Other plants growing around it will gradually be eaten away by it and become nutrients and fertilizers for their growth.

Moreover, all animals and plants that intrude into its territory will be ruthlessly devoured by it, and even adult caimans will not be able to escape its attack. (To be continued.) )
