Su Jing picked up the huge shell and looked back and forth. It is about twenty-five centimeters long, about five catties, the average person can only hold it with two hands, the shell is thick, it looks like a saucer, the left shell is slightly raised, the right shell is flattened, the front ear is slightly protruding, and the back ear process disappears into a round and blunt shape. The surface of the shell is brown, the scale layer at the top of the shell is tight, and the scale layer on the posterior edge of the shell is obvious.

"It's like a white lipped oyster. The more Su Jing looks, the brighter his eyes shine, the white lipped oyster, also known as Pinctada magnadia, white snail pearl oyster, belongs to the tropical, subtropical marine bivalve shellfish, in China is the South China Sea endemic pearl oyster species. Its pearl reserves account for about 90% of the total reserves of all kinds of pearl oysters in the whole province, the pearls produced are large, the color is good, the price is high, it is a precious ornament and medicinal material, it is very popular in the international pearl market, and has extremely high economic value.

However, due to its small number and high value, it is listed as a national class II protected animal and is prohibited from fishing.

"Xiaohu, where did you pick up this white butterfly oyster?" Su Jing asked, he didn't want to break open this white butterfly oyster to see if there were any pearls inside, because he didn't want to kill it, after all, it was a national class II protected animal. I heard that some people are skilled and can open the shell to take out the pearl, and the shell can survive, but that kind of technique is undoubtedly as difficult as surgery, and Su Jing thinks that he does not have that level. Moreover, there is a great deal of chance that a wild shell breeds a pearl, and the probability of having a pearl in this shell is not more than 1 percent.

"Over there. The killer whale turned its head and barked out to sea.

"Take me there. Su Jing took a net bag and diving goggles, jumped on the back of the killer whale, and the killer whale carried Su Jing away through the waves, swimming for about 20 minutes, away from the coast of Sujia Village, close to an uninhabited island, there are many small islands in this sea area, which have not been developed.

When he was about three hundred meters away from the uninhabited island, the killer whale screamed and reminded Su Jing, and then dived into the sea and dived rapidly, even with Su Jing's physical fitness, he quickly felt the pressure in his chest, which was extremely uncomfortable. Man is not a fish and cannot withstand rapid changes in water pressure.

"Slow down. Su Jing hurriedly patted the killer whale and squeezed out two words with an exhalation. The killer whale slowed down and dived slowly, ten, fifteen, twenty meters...... The average person who dives 10 meters already feels the stinging pain of the eardrum and has difficulty breathing, and some professional divers can dive 15 meters or even 20 meters. The limit of diving is the limit of human resistance to water pressure, and it is also the limit of physical functions in the body.

In July 1996, Francesco, a famous diver from Cuba, set a world record for deep diving. Dive 132.9 meters without the help of a breathing apparatus. When he dived to 122 meters, the pressure of water in his front and back was more than 50 tons, and it was observed that his chest cavity of 127 centimeters was compressed to 50 centimeters by the strong seawater.

Su Jing's current physical fitness is definitely far beyond ordinary people, so he slowly dived to more than 20 meters, but he still didn't feel much, and until he reached the bottom of the sea at a depth of about 50 meters, he only felt a little uncomfortable, and there was no big problem.

Su Jing looked at the bottom of the sea through the diving goggles and found that the bottom of the sea was a rocky reef gravel geology, with a small number of seabed plants, and there were many white lipped oysters, some were crawling, some had died, lying quietly on the bottom of the sea.

Su Jing commanded the killer whale to move forward close to the bottom of the sea, turned over a huge white butterfly oyster in front of him, it was empty, and he turned over several times in a row, and finally saw a pearl with a diameter of about ten millimeters lying inside, but unfortunately it was not very round with the naked eye, and the color was average.

Su Jing continued to rummage, couldn't hold his breath and breathed on the sea, and then came down, and he found one pearl after another, some of which were of good and bad quality, and some should be worth thousands of yuan or even tens of thousands of yuan.

"Wow, that's big. Su Jing suddenly saw a shell, more than 30 centimeters long, let the killer whale swim over, opened it, and suddenly stared at the boss, there was a white pearl lying inside, more than fifteen millimeters, and very round, full of luster, no flaws can be seen, although Su Jing is not very knowledgeable, but it can also be seen that the value of this pearl is definitely not low.

Su Jing rummaged for a while, rummaged through almost all the nearby white lipped oysters, and found fifty or sixty pearls, in addition to the flawless one, there were more than a dozen other ones that were not bad in quality, and the others were very average.

"Let's go, look around. ”

Su Jing didn't go back immediately, let the killer whales take him, shuttle under the seabed, and appreciate the scenery of the seabed through the diving goggles, although he was on the beach, he didn't dive so deep, and it was the first time to play freely in the deep sea like this.

Su Jing can see all kinds of corals, seagrasses, fish, shellfish, crabs on the bottom of the sea, the underwater world can definitely be described as bizarre and strange, once Su Jing accidentally touched a clump of coral, but he didn't expect the coral to move suddenly, and then a cloud of black ink sprayed out, which turned out to be an octopus disguised.

Su Jing encountered strange shells, blood corals and the like, and put them in a net bag, this time he didn't want to sell them, after all, they weren't worth a few dollars, but he wanted to take them back to his home collection.

Su Jing still thought in his heart, aren't there many ancient shipwrecks on the bottom of the sea, if he can find one, which is full of ceramics, gold, silver and jewelry, etc., then he will make a fortune, but unfortunately he didn't find a single piece of wreckage.

"Huh, that fish is ......."

Su Jing suddenly noticed a fish, a bit like some kind of precious fish, but unfortunately before he could see it clearly, he saw it burrowing into the coral reef.

Su Jing only the killer whale swam over quickly and squeezed into a piece of coral, and the fish continued to hide, but Su Jing saw clearly this time, it was indeed a wrasse wrasse, it had a high raised forehead, just like the hat worn by Napoleon, so it was called "Napoleon".

Napoleon wrasse is the largest and longest-lived reef fish, generally living for more than 30 years. It has long been traded as a commercial fish, and its tender meat is famously delicious, but due to its small quantity and high price, a kilogram of napoleon wrasse can be sold for $200 and a plate of lip can be sold for $300.

However, studies in most regions have shown that the population of wrasse is declining due to commercial trade, at one point as high as 90 percent. Many juveniles are caught before they reach breeding age, resulting in fewer and fewer adult fish capable of reproduction, and misbehaviour during fishing threatens not only the survival of species, but also fragile coral reef ecosystems.

Listed as endangered in the IUCN Red Book in 2004, it was listed as an endangered species at the 13th CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) Congress held in October 2004.

"Hey, it's an endangered species. ”

Su Jing still won't break the law because of the big profits, but it's always okay to go and watch the Napoleon wrasse, many people only know that the wrasse wrasse is delicious, but they forget that the wrasse itself is also an ornamental fish.

Su Jing controlled the killer whales to shuttle in the coral reef, because the killer whales were large, they could only pick a place with a large gap, and successively found four or five wrasse fish in the coral reef, ranging in size, from a few catties to a dozen or twenty catties.

"me, that one is also Napoleonus wrasse?"

Su Jing suddenly saw a huge figure, his eyes widened at the boss, and he commanded the killer whale to swim over quickly.
