Yang Yi quickly walked to the depths of the sea, did not change into a dragon, after all, there are still a lot of ships coming and going in this water, many ships have submarine sonar or radar, if you find a monster up to 100 meters long, I estimate that it will immediately become the hottest headlines in the world, and when the time comes, it is possible for some countries to transfer warships to search, although it will not affect him, but I don't want to be like those unsolved mysteries like the "Loch Ness Monster".

The lower you go, the less light there is, and when you reach 200 meters below the surface of the sea, it's basically dark, and when you look up, you can see some light, but when you look down, it's pitch black.

Yang Yi put the diving suit into the space, this is also to prevent the diving suit from being damaged by water pressure, although it is a deep diving suit, but it can't stand him to go down to the bottom of the sea for two or three thousand meters, to that depth, the diving suit is no different from a piece of paper, not to say that it has a protective effect, and it is good not to become a burden.

Diving all the way down to a depth of several hundred meters, there are actually very few fish in the sea, most of them will live in shallow water, because there is a lot of food and algae here, which can provide them with the necessary protection for survival.

In the process of descending all the way, Yang Yi encountered many different kinds of fish, including the spotted grouper, commonly known as blue spotted, as well as short-tailed bigeye snapper, multi-toothed snake mullet, pointed plowhead ray, etc., he selectively caught a batch and put it into the space, so that these fish can reproduce in it, which can be regarded as building spatial species diversity.

What surprised him the most was that in this sea area, he actually came across a school of tuna, of course, not the most valuable bluefin tuna, but yellowfin tuna, although not as expensive as bluefin, it is also an extremely high-end ingredient.

From the perspective of fishery utilization, tuna can be divided into six species: yellowfin tuna, bigeye tuna, bluefin tuna, albacore, bonito and masu tuna.

Tuna is not only delicious, but also rich in a variety of nutrients, and is known as a high-end food with "low calorie, low fat, low cholesterol, and high protein" around the world, and also has the reputation of "the king of sashimi", with extremely high economic value and high value.

Different species of tuna have great differences in taste, for example, the average fat content of bluefin tuna can reach 15-20%, which is 2-5 times higher than other tuna species, so the taste is fatty, which is also the reason why bluefin tuna is favored by the world, but when it comes to bluefin tuna, island countries are the most demanded in the world.

Yellowfin tuna, on the other hand, is second only to the bluefin and has a spindle-shaped body with a small head, a long, thin tail, and pink flesh. The dorsal body is blue-blue, with a little yellow, dotted transverse band, the second dorsal fin and anal fin of the adult fish and the small fins behind it are bright yellow, and the first dorsal fin and pelvic fin are yellow, so it is named "yellowfin tuna".

There are 4 or 50 yellowfin tuna in this group, which should have passed by here after migration, the largest body length is more than 2, and the small one is nearly 1 meter, unfortunately I met Yang Yi, and all of them were unceremoniously received in the space, these tuna are also considered to be fish in the upper layer of the marine food chain, plus most of the fierce fish in the space have been taken away by Xia Li, but there is no need to worry that they will starve to death or be eaten by other fish.

Yang Yi was in a very good mood after receiving this group of tuna, and after the sea opened in September, he planned to go to the East China Sea to catch bluefin tuna a few times, the price of a fish was at least hundreds of thousands or millions, and this boat was also built to catch tuna, so it couldn't be in vain, right?

When it reaches five hundred meters under the sea, it is completely dark, if the human beings come in and do not take the submersible, it must be a black eye, maybe they will be squeezed by the water pressure, it is not a problem for him at all, in this darkness his eyes are as unaffected as the day, this is also one of the racial talents of the dragon race, and the water pressure is not a problem, not to mention the physique of the dragon, not to mention these hundreds of meters, even if it dives to the Mariana Trench, it is estimated that it will not have much impact.

When he was diving all the way to about a thousand meters, he encountered an ugly-looking strange fish, almost a dozen centimeters in appearance, with no scales on the surface of its body, densely covered with fluffy fine spines, and thick skin. The head, body, and fins are black, the mouth is black, and the inside is covered with long fangs, and a small white "lantern" sticks out of the top of the head.

Seeing this ugly and fierce, very "impressionistic" and random strange fish, Yang Yi smiled and stopped. He must know this kind of fish, but the real thing is the first time he has seen it, I still remember when I was in college, a few brothers in the dormitory gave him a target, and the first movie I watched was a cartoon "Finding Nemo", in which the clownfish Marlin and the blue Tang kingfish Dolly were at the bottom of the sea, they encountered this kind of fish, and they were almost eaten by it.

Although the cartoon is also very ugly and fierce, but after a lot of beautification by the hands of the original artist, he became interested in this fish at that time, and deliberately went to send some information, remembering its scientific name "Anglerfish".

Anglerfish are also called deep-sea anglerfish or anglerfish, and they are called "lanternfish" on the Internet, because the mimic bait on the top of the head resembles a white lantern. Mainly living in the area of 200 to 4000 meters below the sea surface, there are more than 340 species in 18 families in the world, although there are many types, but their appearance characteristics are about the same, which can be summed up in one word - ugly, and it belongs to the level of the ugly sky!

They also have a very strange feature, which is the extreme anisogeneity and asymmetry between females and males, female anglerfish are much larger than males, and at their limits, female anglerfish are 70 times longer than males and weigh 500,000 times more than males. The difference in size between males and females is so great that scientists thought that there were no males in the early 100 years after the early discovery of the anglerfish.

And that's not even the weirdest thing, the strangest thing is that the males seem to have been born to reproduce. The male anglerfish sniffer and eyes are very well developed, they can make a special smell from the female, and once the female is found, the male anglerfish bites the female's abdomen and then goes blind because it no longer needs visual aids to find a mate.

The combination of the two forms a fibrotic tissue, which firmly fixes the male fish on the female fish, and then the organs on the male fish gradually degenerate and disappear, leaving only the reproductive part, becoming an immovable appendage of the female anglerfish, and becoming an indispensable part of the life of the female anglerfish.

The existence of male fish seems to be to eat the "soft rice" of female fish, and the only chance to turn the tables against the wind is also the day when the female is found. As long as they can hang on to the females, they can live a peaceful life from now on, and the rest of the days are only a few ...... for reproduction

And the life span of the anglerfish is very long, a female anglerfish can survive for 30 years, in the "fish sheng" there will continue to be male fish to find, parasitic on its body, for these "soft rice men" who come over, they have never refused, so it is not surprising to see a female anglerfish hanging several appendages below, it is not surprising at all, it is their male partner.

And it is worth mentioning that it is such an ugly fish, which is also an expensive thing to do in the island country, just like the "stone fish", which is loved by the people of the island country, and is the first choice of the island people's hot pot base.

It is estimated that the anglerfish themselves did not expect that they had already worked hard to look so "ugly", and they still did not escape the clutches of humans! Yang Yi waved his hand to collect these glowing deep-sea anglerfish into the Dragon Ball space, although he has no evidence of this kind of anglerfish, but as far as he knows, it should also be the remnants of alien creatures that invaded the earth in ancient times, and after hundreds of millions of years of changes, they have completely become earth creatures, but their ugly and strange appearance and strange reproduction methods have been retained.

Yang Yi stood on the uneven ground at the bottom of the sea more than a thousand meters below the sea surface, and the surrounding sea water automatically flowed through his side, without any effect on him.

At this time, he was standing next to a piece of silver-white metal, most of which was buried in the sediment on the seabed, only a small part of it was exposed, and in Yang Yi's perception, this thing was at least a hundred meters in diameter.

He grabbed the edge with both hands and dragged this thing out of the mud and sand, and with the action, a piece of mud and sand surged, and the sea water was dim, but it was located on the dark bottom of the sea, and no one could find it except Yang Yi.

After shaking a few times, the mud and sand and parasitic plants attached to it all fell down, revealing the true face of this thing, if any science fiction fan saw it, he would be shocked, and then scream and pounce, and there must be a word "UFO" in his mouth!
