Chapter 887: Holding the Hand

Only after entering the river did everyone realize that crocodiles are much more than just those who climb on the shore to bask in the sun.

Sections of "dead wood" floated to the surface without warning, as if they had been buried under the silt of the river before, until the rafts on the river stirred the water flow and dispersed the sediment, allowing these big pieces to float.

The tens of millions of viewers in front of the screen all know what these dead trees are, out-and-out Nile crocodiles!

They are not those little guys called Nile crocodiles in the Egyptian desert. In fact, the average body length of West African crocodiles is less than 1.7 meters. Instead, the average length of adult males is 3.5 meters, and the average length of adults is more than 4 meters. Huge thing!

Space is three-dimensional. When the body length doubles, the weight increases exponentially.

The West African Nile crocodile is 1.5 meters long and weighs no more than 30 kilograms. However, the 3.5-meter Nile crocodile can weigh a terrifying 300 kilograms. Compared with doubling the body length, the weight directly doubles. Ten times more!

If two crazy crocodiles were to attack forcefully, they might be able to overturn the entire raft just by relying on their weight, and then it would fall into the water, but Bifang would have no choice but to make the decision.

The viewers who realized this were all frightened. For a time, the number of viewers and comments in the live broadcast room surged simultaneously.

[So many, is this too much? The feeling on the surface of the smooth water is double digits]

[How many crocodiles are there on earth? The African rivers are too scary, right?]

[What the hell, you won’t really attack, right?]

[It all came out at once, the feeling is too keen]

Compared to the panicked audience, Bi Fang seemed to be there and not worried. He had experienced too many similar scenes.

Facing the battlefield for the first time, new recruits will fight in two ways, but veterans of hundreds of battles will never be able to do so.

"Just looking at the appearance, the Nile crocodile is covered in scales. Many people subconsciously think that their touch is weak, just like the skin wrapped with calluses is often slower to touch than normal skin. In fact, it is just the opposite. The Nile crocodile's body surface There are many sensory organs that are more sensitive than normal human skin."

As soon as these words came out, everyone was shocked.

How could the scales, which looked very thick, be more sensitive than human skin?

Isn't this a joke?

"The crocodile's scales are just an expression. We need to look at the essence through the expression. In fact, more than 100 years ago, people discovered that there are many small, protruding black spots on the head, jaws, mouth and between the teeth of the crocodile. These small black spots, Well, the little black spots are not the dirt left by long-term survival in the wild, but they are there from birth.”

"In the developing caiman and its embryos, small black spots on the head have already appeared before the skin begins to divide and form scales. The Nile crocodile is even more exaggerated, with additional small black spots developing all over the body. At that time People see it as a unique organ."

"But the exact functions of these organs have been poorly understood before. Only now do we have a general understanding. In fact, we can roughly understand their functions from their names."

"Those raised black spots are unique sensors, which we call dome pressure receptors, or integumentary sensory organs, which are sensory organs."

"But the crocodile's outer skin sensory organs are completely different from other vertebrate sensory organs. It combines the detection of touch, cold and heat, and chemical stimuli, evolving into an advanced armored and sensitive skin that is even more sensitive than our human skin. many."

"This means that crocodiles can detect surface pressure waves, respond to changes in water pressure, track the movement of prey in the water, and quickly find prey even in the dark."

"At the same time, thermal sensitivity allows them to maintain body temperature by alternating between basking in the sun and entering cold water, and chemosensory abilities help them find the most suitable habitat."

This is why Bi Fang insisted on using a skewer instead of a rowing oar. The water waves caused by the rowing oar are much larger than those of the skewer, making it easier to attract the attention of the crocodile.

Regardless of whether the crocodile dares to attack or not, it will attract less attention or less attention.

[This is too exaggerated]

[Is he so awesome? 】

[No wonder all the nearby crocodiles reacted as soon as Lao Fang’s raft entered the water]

[The miracle of living things, natural evolution is so amazing]

Bi Fang nodded and said: "It is indeed amazing. The sensory organs of other vertebrates cannot be compared to it. For example, our skin has a distributed sensing system, and crocodiles concentrate this distributed sensing system." , turned into a distributed multi-sensory micro-organ.”

"A more specific related paper was published in the Central State Journal "Evolution and Development". If you are interested, you can check it out."

The audience is now somewhat used to the practice of dumping papers when they disagree.

This further proves Bi Fang's professionalism, at least other wilderness survival anchors do not have such ability at all.

Not everyone has a memory palace.

"But we don't need to worry for the time being. If the crocodiles really want to attack, you won't be able to see them surface. If they can surface, it means that they have no desire to attack yet."

Crocodiles usually float on the water with only their eyes, mouth, and nose exposed.

It looks like you are basking in the sun, but it is actually a standard movement for ventilation.

"If the crocodile really intends to attack, it will not reveal its body. Instead, it will lurk quietly. After all, who would not let the enemy see themselves before launching a sneak attack? This is too stupid."

"Furthermore, crocodiles have a keen sense of body and are farsighted. They can better observe the status of their prey underwater."

Crocodiles are out-and-out hyperopic. They can't see clearly at a distance of dozens of meters. On the contrary, due to the different refractive indices of light in water and air, crocodiles can rely on their body senses to observe more clearly underwater.

"They came out to breathe now, probably because I startled them. They just came up to breathe after observing for a while."

"Besides, we are on the raft. The whole target is too big for the crocodiles. They won't attack easily."

Bifang analyzed calmly and slowly pulled the shovel in his hand out of the mud.

For the crocodiles, the whole raft is too big. Maybe the length of the raft itself is only more than three meters but less than four meters, which is not as long as some well-developed adult Nile crocodiles, but Nile crocodiles can't grow more than two meters wide!

The area of ​​the whole raft is close to eight square meters. With Bifang standing upright on it, the overall height is more than two meters and the volume is close to 16 cubic meters. From the crocodile's senses, this is a monster among monsters, and a monster that can live in water.

Maybe it's the king of hippos?

Even ordinary hippos dare not attack, let alone the king of hippos.

This is probably what the crocodiles think.

[Too cool, Fang Shen really has the upper hand, and the crocodiles are in a state of panic]

[This is probably a great god]

[The crocodile's underwear has been touched]

[Underwear? Let me see]

Whether it is external sensors, farsightedness, or breathing, Bifang has shown an extremely detailed understanding of the crocodile, and even the psychology is in a state of panic, almost predicting it. Such foresight has relieved the audience's nervousness.

Humans are often afraid of the unknown, but when the opponent's next step can be accurately predicted, the fear will greatly subside. Of course, there will still be fear.

The row of crocodiles on the river bank still looks scary.

Especially since all the crocodiles are motionless, if they didn't know that this is in the African savannah, many people might think they are fake crocodiles.

Those in the river silently surfaced beside the boat, stared at the raft quietly, and finally sank silently.

As the pole moved, Bifang gradually rowed out more than ten meters.

Just when everyone thought they could get through safely this time, the water waves next to the raft slowly rippled, extremely dense.

Bifang frowned.

Is it a crocodile?

No, if it was a crocodile, the water surface would not show such a phenomenon.

Such dense ripples looked more like the ground was shaking.

Bifang raised his head.

On the plain in the distance, a dark thin line appeared in the field of vision, and it was still getting thicker. It was obviously approaching and moving very fast.
