Fang Hong crossed his feet on the vine: "Nash Waubyander once said that when sleeping in the rainforest, you should pay attention not to fierce beasts, but to floods. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo”

"Wait a minute, Brother Gun, who is this, is he famous?"

"I made it up? ”

"This is obviously really made up by Brother Gun. ”

"I'm going, I've been bitten by a snake for ten years, I'm afraid of the well rope, and Brother Gun is afraid that it's because he was flooded last time, so now he doesn't want to sleep on the ground after entering the forest." ”

Fang Hong waved his hand: "Bye-bye!"

"Wait a minute!"

"Huh, what's wrong?"

"Let me advertise, the gluttonous adventure king Q group, 550888792, kidnapping cute girls. ”

"Fuck, fuck off. ”

Early in the morning, the live broadcast started again.

The first to cut in was not Fang Hong's big face, but the quiet river.

At dusk, the sunlight cuts through a gap between the two dense forests on the river, and the light splits the river in two.

The "buzzing ......" picture slows down, and the occasional ripples on the surface of the water seem to be frozen.

The lens zooms in and is fixed in front of a flower.

A small bird hovers in front of a flower, its long beak sucking in honey.

The bird's wings are so fast that they can't be seen clearly at all, only the wings are shaking.

"Hummingbirds, the smallest bird in the world, exist only in the Americas. Its wings are fast enough for it to hover in the air. ”

"In China, there is a similar but actually different bird called the hummingbird. Globally, there are hummingbirds in the Americas and only kingfishers in Ecuador, while on other continents there are only kingfishers without hummingbirds. It seems that beware of birds in this field, the two are not compatible. ”

Or rather, before the continents separated, they were the same species, and in a gradual evolution, the difference became greater and greater until they were completely different.

"In the process of evolution, hummingbirds have chosen a faster speed of wings, which exceeds the speed of AC cycles per second in China, so they can levitate in front of flowers to collect honey, which is the only one among birds that can do this. The kingfisher, on the other hand, has chosen flight speed in its evolutionary journey, reaching speeds of up to 60 kilometers per hour when it paddles across the water to catch fish, enough to pick up a fish before it can react to the surface. ”

"Next time I have a chance, I can take everyone to see the kingfisher. ”

The camera picks up until it reaches normal speed, and the hummingbird stays in front of the flower for three seconds before its wings flutter and disappear into the frame.

The line dividing the sun on the river slowly disappears from west to east.

Night falls.

On the riverbank, a lizard cautiously appeared under a tree, then burst out and rushed onto the river.

It doesn't swim in the water, but spreads its hind legs and keeps running on the water.

"Jesus is a lizard, and he floats on water. These lizards, also known as basilisk lizards, have scales on the soles of their feet, which can form bubbles on the water, borrowing the strength of the wide soles and bubbles to tread water. ”

In the sports shot, Jesus lizards lift their legs and fall, and their horns are pushed to the sides: "This is the reason why they can stand upright on the water, and by thinking about the sides and diagonally downward, they can prop up and rush forward." ”

"In the Amazon, speed is king, especially for nocturnal animals, each faster than the other, and even birds and reptiles are on the evolutionary route to miniaturization and rapidity. ”

Biologically speaking, birds and reptiles are born with a defect in speed.

Birds need strong pectoral muscles to flap their wings, and flying is far more strenuous than running on the ground, so most birds that evolved from dinosaurs chose to be miniaturized because there wasn't as much food to provide the huge amount of energy that pectoral muscles needed.

The muscle strength and bone strength of reptiles are inherently inferior to those of mammals, and it is very rare to be able to evolve to this point.

Most of them have opted for miniaturization in pursuit of speed.

"The natural world is magical and magnificent, and every species, after encountering natural predators, will have two evolutionary routes, one is to go head-on, and grow larger and larger until it can fight against natural predators. For example, the dragon was once preyed upon by sharks, so it began to evolve towards large-scale, and finally became the top sea overlord for shark hunting. The other is miniaturization, where speed is king. ”

"But the natural world is fair, it doesn't mean that if they are big, they can survive forever, and once they encounter climate change, the blow to them will be devastating, because large-scale means that the ability to adapt is infinitely reduced. And miniaturization doesn't mean you can do whatever you want, because your opponents are getting smaller too. In South America, large animals have become extinct, and large carnivores have evolved into cautious carnivores, and are accustomed to coming out at night, such as tiger cats. ”

In just an instant, a black shadow scurried through the forest: "That's tiger cats, it's almost impossible to get a picture of them, unless you leave a camera in their habitat for a year and a half." ”

The last species of the night shot appears.

At the water's edge, under a stone, the water was babbling, and a dark brown animal was constricted, just below the stone.

"Vampire bats. ”

Vampire bats have a head that looks like a pig's head, a nose that resembles a pig, and ears that are large, but erect.

"It's listening to the water. ”

The next moment, the vampire bat spreads its fleshy wings and streaks across the water.

"Bats are mammals and the only flying mammals, in our hometown, called salt mice. ”

They look a lot like rats, but they're not rodents at all, they're pterocodics.

"This kind of bat is very dangerous, because they carry the rabies virus, once bitten, you need to be vaccinated immediately, the rabies virus will lurk in the nerve veins, continue to the brain stem, once into the brain stem, immediately onset, after the death rate of 100%. ”

Bites by dogs, usually legs, have a very long incubation period, which can reach a maximum of several years or even ten years. But when a bat attacks a person, it must be the face and torso, and it will become ill in a few days.

"It has detected the fluctuations of the water streaks and determined the location of the prey. ”

Bats emit ultrasound waves, which then receive the reflected ripples to form a three-dimensional picture in the brain. In other words, bats are able to see sounds, their own voices. “

On the surface of the lake, the bat suddenly spreads its wings in full swing while gliding, stops the upper part of its entire body, rushes forward with its legs, and changes from flying close to the water to standing on its own in the air.

Catch it in the water with both paws, pick up a fish, then throw the fish into the air, catch it twice, turn its head and fly away: "It didn't catch it firmly the first time, so it performed an acrobatic trick in the air." ”

"Different subspecies of vampire bats will target different targets. In South America, they mainly feed on fish and occasionally attack animals. However, they are all very small, and there is only a record of vampire bats attacking children in Brazil, and they do not attack adults. ”

The bats disappeared, and the nighttime footage was combed.

The picture cuts back, Fang Hong is squatting in front of a flower, holding a wooden stick in his hand.

"Brother Gun, is this it?"

Fang Hong smiled: "I don't know if this thing is called a flytrap or a pitcher plant, anyway, it is a carnivorous plant." ”

"There are more than 500 species of carnivorous plants in the world, and I don't recognize this one. ”

The plant in front of you, in the shape of a pitcher plant, has a trumpet-shaped flower.

However, its mouth is not smooth, but has spikes like those of the Venus flytrap, with both sides, and it looks like an open mouth.

"Brother Gun, if you stab it like this, it won't move, what kind of fly catcher!"

"Generally, carnivorous plants have two mechanisms, one is like pitcher plants, emitting a foul smell, driving away large animals but attracting mosquitoes to approach, its flower wall is very slippery, unstable, go up and don't want to come out again. Once you slide to the bottom, you will be stuck with a very sticky slime. The other is the Venus flytrap mechanism, which shrinks when touched by mosquitoes and traps mosquitoes to death. This one seems to have two mechanisms at the same time. ”

Fang Hong held the wooden stick: "You see the next time I poke it, it will bite the wooden stick." ”

The stick went down, not moving.

"Mistakes, mistakes. Fang Hong poked again, and this time, the carnivorous plant's canine-toothed prickly mouth suddenly tightened, but he didn't eat anything.

"If you touch a thorn alone, it will not react, and you have to touch two thorns before it closes its mouth, and this physiological movement mechanism has not yet been figured out by scientists. The function is to prevent the prey from touching the outside in vain. It should take a few hours to open after it closes, and the real mosquitoes have been killed in these few hours. This time, though, it bit the air. ”

"Brother Gun, is it really okay for you to disturb other people's hunting like this?"

Fang Hong nodded: "That's right, I still have to eat breakfast, I don't bother to pay attention to it." ”
