Just as everyone was laughing as they watched Wu Xueying nervously, the fish gathered by the river and stared at the shore suddenly started to riot. Countless small fish swam into the surrounding water in panic, and a white area immediately surged on the water surface.
ripples. Everyone quickly looked at it intently. A slender black shadow suddenly emerged from the dark river water, and its slender body twisted towards the fish in the water.
"Oh, water snake!" Lingling pulled Wu Xueying and screamed and took a step back. Professor Wang looked intently, and he followed and said, "This is not a water snake, this is an electric eel, the natural enemy of this piranha!"
In his voice, the dense fish in the water had disappeared into the dark river water around it, and more than a dozen piranhas had already turned their belly floating on the water. The slender big fish in the water looked at the crowd on the shore coldly
It suddenly opened its big mouth and bit a small fish floating on the water surface, then quickly shook its tail and drilled into the water. In a blink of an eye, it disappeared into the water.
The small fish that were still dense in the river disappeared in a blink of an eye. A small fish with their belly floating among the enlarged water lines. Wu Xueying looked at the water in shock and shouted: "Professor Wang, these foods are here.
Why did the mermaid die in an instant? How did this big snake-like fish get? It's so amazing! Why did it eat only one?"
Professor Wang stared at the dozen small fish that were climbing up the water and replied: "This big snake-like fish is called the electric eel. It is one of the most terrifying freshwater animals on the earth. It can release a single one in an instant.
A strong current can not only electrocute this piranha, but also can electrocut an adult on the spot, and the voltage generated can reach 300 to 800 volts. This electric eel is the natural enemy of these piranhas. It is not just
Eat one, but I was frightened when I saw us standing on the shore. After a while, it would come out and eat the remaining fish." As I spoke, there was a sudden "rattle" sound in the water, and then I saw another small one.
The fish was quickly pulled into the water.
Lingling and the others looked at the ripples in the water. Lingling asked in surprise: "Professor Wang, how can a fish generate such a high voltage?" Xiaoya, Wen Meng and Wu Xueying looked at Professor Wang in discomfort.
Professor Wang explained: "The reason why electric eels discharge electricity is because there is a generator at the tail, and this generator comes from its muscle tissue. There are many muscle thin slices in the muscle tissue on both sides of the fish's body, these thin slices
Just like a piece of batteries, the tail of the electric eel is the positive electrode, the head is the negative electrode, and its body is like countless "batteries" connected in series, so the electric eel can generate a very high voltage in an instant."
After hearing this, Lingling shook her head and said in horror: "There is nothing in the world. If you are powered by such a high voltage in the water, you will drown even if you are not electrocuted. This kind of electric fish is so scary!"
Yu Jing, who was standing aside, saw Lingling and the others in shock, looked at the calming water surface and said, "This is the ecological balance of nature. This kind of piranha is very cruel. If they are allowed to reproduce in a large amount without restrictions, the water will be
All creatures will eat them up, so the emergence of natural enemies of piranhas such as electric eels can control their number." She followed Professor Wang and said, "Professor Wang, you are an expert in biology research, don't you?
”
Professor Wang turned his head and looked at Yu Jing and nodded and said, "Yes, this is the ecological balance in nature. Researcher Yu, you have lived abroad for many years and you should know this kind of piranha very well. I read it from the relevant information.
After that, the living conditions of this type of piranha are very harsh. They only live in water at about twenty degrees Celsius. After this water temperature, their reproductive ability will become extremely weak, and electric eels are also accompanied by them in the waters where they are located.
This kind of natural enemies, so we rarely see such a large group of piranhas outside."
Yu Jing sighed: "Yes, I did see this kind of piranha when I was traveling abroad. Speaking of which, this is the survival of the world. There is competition between species and within organisms, any species
The disorderly development will destroy this balance in nature. Electric eels and natural conditions suppress the scale of this vicious fish, which is a manifestation of ecological balance."
She followed Wan Lin and said, "Leopard Head, the river in front of her looks very calm, but there are murderous intents inside. Everyone should be careful when acting and try to stay away from the river!"
Wan Lin immediately replied, "Okay!" He followed the team members around and said loudly, "Everyone remembers Mr. Yu and Professor Wang's instructions, and try to stay away from the river." As he said, he looked up at the dark front with some concern.
Looking at the cave, he shouted, "Xiaohua, Xiaobai."
Wan Lin's shouts were silent, and an echo sounded from the deep cave. The roars of Xiaohua and Xiaobai were faintly heard from the dark cave in front, and waves of "buzzing" echoes echoed throughout the cave.
Wan Lin heard the sounds of the two leopards, and the expression on his face immediately calmed down. He looked at the people around him and ordered: "Everyone be careful and go!" After saying that, he stepped on the shore with a flashlight and a wind knife.
The wet rocks beside him walked towards the depths of the cave. Xiaoya and his men immediately grabbed Yu Jing's arms and followed. Dali and Dazhuang also grabbed Professor Wang and Professor Xiao's arms respectively, and helped them forward together.
Walk away.
The cave in front is dark and rugged, and the raised rocks on the shore are very slippery. Wan Lin and Feng Dao hand clutched the raised stones or cracks on the cave wall, slowly moving deep into the cave while carefully observing.
On the shore, other team members followed very carefully.
Although the river water here is two or three meters away from the cave walls on both sides, the slope of the shore is steep. If you are not careful, you may fall on the slippery rock and slide into the dangerous river next to it. So everyone's
The movements became careful and the speed of travel became slower.
While walking forward carefully, everyone raised their flashlights to shine on the dark cave walls on both sides, hoping to find the cracks or caves leading to the mountains outside earlier.
Wan Lin and his group walked forward for seven or eight hours in a row with expectations, but there was still no passage to the outside world in the dark cave. Xiaohua and Xiaobai, who had been in the darkness in front, also quietly.
At this time, Wan Lin walked to a huge rock in front and stopped. He raised his flashlight to shine into the dark cave in the distance. The cave and the dark river reflecting light were slanted to the left hundreds of meters in front of him.
Turning around, the deep cracks and raised rocks on the front hole wall have clearly appeared in the flashlight column.
