My Deep-sea Fishery

Xiang Yang is right to do so.

Although the life level of amphioxus is lower than that of fish, and its body is only a few inches long, it is a bridge connecting invertebrates and vertebrates. It is between invertebrates in terms of embryonic development and morphological structure. Between the two are important living specimens for the study of animal evolution.

Xiang Yang held the amphioxus and swam back to the surface, and took off the helmet on his head.

"Xiang Yang, why did you come up here?" He Mingde wondered, "Is this little fish like a shoulder pole worth much?"

It is not nonsense to say that amphioxus is like a shoulder pole. The whole body of amphioxus is colorless and transparent, with two pointed ends and a wide center, resembling a small pole. Some fishermen in the southern coast call them "pole fish".

"It's not worth the money, this fish is a protected animal." Zhang Qicheng was a little nervous, "Brother Xiang, we'd better do one thing less than one more thing. Let this fish go right away?"

Among all the people present, Zhang Qicheng must be the one who said he was nervous. This amphioxus was kicked by Zhang Qicheng at the bottom of the sea. If it died after catching it, Zhang Qicheng would inevitably encounter some troubles when the news spread.

Xiang Yang looked at the small, colorless and transparent fish in his palm and said with a smile: "Don't worry, this fish is alive and well and not injured, it can be released."

Zhang Qicheng breathed a sigh of relief when he heard the words, "Show me."

Xiang Yang handed the amphioxus to Zhang Qicheng.

Zhang Qicheng hesitated for a moment, "Can I take this fish back and raise it?"

Amphioxus was first discovered in Wenchang Pavilion, so many parents with school-age children like to keep an amphioxus in their study, which means Wenchang.

Xiang Yang shook his head, "Most of the lancelets kept in the study are artificially bred, and it's not suitable to take the wild ones back."

Only then did Zhang Qicheng sigh, yes, how could protected animals be brought home privately? Reluctantly, he released his five fingers and released the amphioxus.

As soon as the amphioxus escaped from Zhang Qicheng's grasp, it immediately swung its tail and burrowed towards the bottom of the sea.

He Mingde watched Zhang Qicheng release the amphioxus, and said in amazement, "This little fish is actually a protected animal."

Xiang Yang smiled. In the ocean, some animals whose weight is measured in tons are not protected animals, while some animals whose weight is measured in grams are protected by the laws of many countries. Calculated by weight and volume.

Xiang Yang was about to explain with a smile, when suddenly he saw a snow-white wave appearing on the sea in the distance, and that wave was moving rapidly towards this side.

Xiang Yang's face changed instantly. The reason was that it was a swordfish. Adult swordfish sharks had to walk with their tails between their legs when they saw it. A swordfish moving at high speed could even sink a huge fishing boat. In the 20th century, World War II There has been a precedent for a high-speed moving swordfish crashing through a transport ship protected by fifty centimeters of thick planks.

"Run away, run to the shore." Xiang Yang shouted quickly.

He Mingde and Zhang Qicheng still don't understand why they are going to run ashore all of a sudden, even if they speak well.

But Xiang Yang didn't care about explaining, he took Zhang Qicheng with his left hand and He Mingde with his right hand, and fled towards the shore desperately.

Swordfish, also known as swordfish, has a super speed and is the fastest swimmer among all marine organisms found so far. Adult swordfish can reach a length of up to 6 meters. It is an extremely ferocious carnivorous fish. Its The upper jaw is shaped like a long sword drawn out of its sheath, sharp and hard.

The reason why the swordfish is fast is precisely because of the sharp sword growing on its upper jaw. The sharp sword can help the swordfish greatly reduce the resistance of the water when swimming. It is recorded by scientists that the swordfish swims the fastest The speed is 119 kilometers per hour, which is faster than most vehicles on the highway.

At the same time, the upper jaw, which is shaped like a sharp sword, is also the stabbing weapon used by swordfish to hunt other marine animals.

Xiang Yang is very anxious now. Although he seems to be only a dozen meters away from the shore, and the swordfish is at least two hundred meters away from him, but considering the walking speed of himself and others in the sea, and considering the speed of the swordfish He is not safe now at the speed that surpasses the ocean.

He Mingde and Zhang Qicheng were a little dazed when they were dragged towards the shore by Xiang Yang.

"What's going on? Why are we running?" Zhang Qicheng asked anxiously while running hard towards the shore. The three of them said they were running, but in fact, due to the huge resistance of the sea water, they were slower than walking on the shore.

"We are being targeted by Swordfish." Xiang Yang said.

"Damn it, Swordfish?" Zhang Qicheng was taken aback.

He Mingde's face turned pale, and he hurriedly turned his head to look behind him.

He Mingde's face twisted when he saw the white waves behind him, "How could there be a swordfish here? How could the swordfish chase us?"

In fact, Xiang Yang couldn't understand why there was a swordfish in Qinglong Bend, and more importantly, why that swordfish came straight to him.

Judging from the habits of swordfish, although they are ferocious, they have very little courage, let alone human beings. If they are not provoked, they will not even approach large fish such as wrasse, let alone attack.

Judging from the current environment, the sea water in the Qinglong Bend sea area is extremely shallow, such a shallow sea area is not suitable for large marine predators like swordfish to swim, and it is getting late now, hunting now is not in line with the work and rest of swordfish .

Wait, it's getting late!

A flash of lightning flashed across Xiang Yang's head, and he suddenly understood why the swordfish would not let him go.

Swordfish is a warm-water migratory fish species in the middle and upper layers of the ocean. They have a wide range of activities, generally at a depth of 200-600 meters, but when food is scarce, they will also hunt at depths greater than 650 meters. The maximum depth can reach as deep as 800 meters under the sea.

What kind of fish are there on the bottom of the sea at a depth of 800 meters?

Monkfish!

The corner of Xiang Yang's mouth twitched slightly. The characteristic of monkfish is that there is a lantern hanging on its head. This swordfish definitely regarded itself with the searchlight above its head as a monkfish.

As for whether the swordfish can kill the equally fierce monkfish?

The answer is yes.

Swordfish are among the top predators in their depth range, and their diet includes all other pelagic fish, tuna, mahi-mahi, flying fish, squid, monkfish are the prey of swordfish.

After thinking about this point clearly, Xiang Yang sighed, and could only move as fast as he could to the shore.

It's not that Xiang Yang doesn't want to turn off the searchlight on his head, but it's useless to turn it off now, because the cunning monkfish will put the lantern on its head in its mouth when it encounters a swordfish, but it's still very bad luck few.

Swordfish have keen eyesight to observe prey. If Xiang Yang turns off the searchlight on his head now, it will only make the swordfish whose sight is blocked more sure that Xiang Yang is a monkfish.
