Xiang Yang also became serious. He was not afraid of the anglerfish alone, but he felt a little overwhelmed when facing the anglerfish and protecting Professor Chen and Supervisor Li at the same time.
Although the anglerfish has a mild reputation and is famous for its lantern shape, it can actually be as ferocious as a flathead catfish.
Anglerfish like to hang lanterns to attract prey. Normally, when the lanterns attract an invincible and ferocious marine predator, the anglerfish will hold the lantern in its mouth and run away. But when it is blocked by marine predators and cannot escape, or when food is extremely scarce, it will desperately attack enemies that are much larger than itself. It is really very ferocious, and even sharks have to take a detour when they see it.
"Hurry up and get ashore." Xiang Yang looked at the anglerfish swimming towards him and said hastily, "If we get caught by the anglerfish, we're done for."
"cannot."
"no."
Professor Chen and Professor Li said almost at the same time: "We can't swim as fast as the anglerfish in the water. You guys go up, and I'll stay and deal with the anglerfish."
Xiang Yang was almost scared by these two old men. Are they kidding me? They are going to deal with an adult anglerfish in the sea.
Although the anglerfish species in shallow waters may be preyed upon by large fish such as sharks and groupers, the anglerfish species in deep waters can be considered the overlords of the deep sea. Excluding other undiscovered deep-sea predators, the anglerfish has almost no natural enemies.
After Professor Chen and Professor Li got to know each other, Professor Chen spoke up, "Xiang Yang, you go up first. Professor Li and I will leave this here."
Xiang Yang said quickly: "If you want to go up, you guys should go up. I'll hold the monkfish back."
"What are you using to drag?" Director Li Bo took off the shark skin backpack on his back and took out a silver-white flashlight-like object from the backpack. "Don't worry, we have this."
"Stun gun?" Xiang Yang blinked. "Will it not harm myself or other marine animals?"
"Don't worry. If the diving equipment we are wearing can't even block the electric current, then it's worthless." Director Li Bo said, "As for whether it will electrocute other marine life, I don't think we are talking about that now."
Chen Yu said: "Basically, it will not affect other marine life. Although seawater can conduct electricity, the resistance of water is also very large. Basically, it is difficult to cause harm beyond five meters, and basically there will be no feeling beyond twenty meters. In addition, the electric gun equipped by our research team is a special electric gun made to imitate the electric eel. Although the power is as high as 650 volts, such a strong voltage is enough to kill a cow, but the current generated during discharge is extremely weak, generally less than 2 amperes. Although it emits direct current, the discharge frequency can reach 300 pulses per second, so each discharge time is extremely short, which belongs to bioelectricity."
Xiang Yang shook his head to indicate that he didn't understand.
Professor Chen Yu and Director Li Bo felt much more relaxed after each holding an electric gun.
Professor Chen even had the mood to explain to Xiang Yang: "Then you should treat me as an electric eel now, do you understand now?"
Xiang Yang knew about electric eels. The electric eel's discharge organs were on both sides of its body. Most of its body or important organs were covered by highly insulating structures. It was like a big battery in the water. The current passed through the path with the least resistance. Therefore, when discharging in the water, the current would be transmitted through the water. Since the resistance of water is smaller than that of the electric eel itself, it would not shock itself when discharging.
However, if the electric eel is caught in the air, the resistance of the air is greater than that of its body. If the electric eel discharges electricity, it will shock itself. In addition, if the electric eel is injured and the insulators on both sides are damaged at the same time, a short circuit will occur when it discharges electricity, just like two exposed wires.
Xiang Yang once watched a documentary. In a river, there was an electric eel about 1 meter long that was bitten by a crocodile by the river. The electric eel struggled and discharged electricity. The crocodile was electrocuted and finally died with its belly turned upside down. The electric eel itself was also electrocuted to death.
In the film, the crocodile did not move at all after biting the electric eel. Its entire big mouth was hanging on the mud on the shore and its body was shaking constantly, obviously from electric shock. After being exposed to hundreds of volts of high voltage for more than 20 seconds, the crocodile obviously could not hold on and began to turn over, revealing its white belly. Its front and back legs were stiff and motionless, and it was suspected to be dead. However, during this whole process, the other crocodiles in the same river and within ten meters of it were not hurt at all.
In a nutshell, this electric gun can only be used in water. You will not get shocked when using it in the ocean while wearing this diving suit. The effective attack range of this electric gun is only ten meters and it will not harm other marine life. It is specially used for self-defense by researchers when diving.
Xiang Yang was envious. Fishing with trawling nets by fishing boats really depends on luck. Xiang Yang's main way of making money is actually diving and fishing.
But in fact, every time Xiang Yang led the crew to dive, he was very nervous. He was actually afraid of suddenly encountering some ferocious marine predators while diving. If this electric gun could be equipped on the ship, it would undoubtedly be able to completely solve Xiang Yang's worries. In the future, when Xiang Yang led the crew into the water, even if they encountered sharks, they would be able to escape safely.
This thing is definitely a diving artifact.
Xiang Yang immediately asked: "Teacher, Director Li, can this electric gun be sold to the public?"
"Yes, it can. It doesn't have much technological content, but it can only be used underwater, and ordinary diving suits don't have insulation or resistance capabilities. You can just buy it as a collectible." Director Li Bo said.
It might be because Xiang Yang and his group were huge in size and their large number scared the anglerfish, or it might be because the anglerfish's eyes had degenerated after staying in the deep sea for a long time, so it hasn't noticed Xiang Yang and his group yet. In short, after a long time, the anglerfish was still wandering there and didn't swim over, so Xiang Yang and his group were in the mood to chat.
"Don't all diving suits on the market have resistance function? Or is the diving suit we are wearing now customized and specially equipped with resistance function?" Xiang Yang asked.
"That's not the case. Insulation technology is not that difficult. Many diving equipment on the market also use resistance technology. However, this type of diving equipment must be fully enclosed. I won't talk about other things about fully enclosed diving equipment. The hood alone costs at least four figures."
Director Li did not continue speaking. He thought Xiang Yang would give up in the face of difficulty. After all, it was rare for a domestic fishing boat to spend tens of thousands of yuan to buy a set of diving equipment specifically for a sailor.
Xiang Yang's eyes lit up.
Xiang Yang didn't know what diving equipment other people's boats used, but the diving equipment on his boat was fully wrapped, so he could use this electric gun.
