Happy Fishing Farm

to the bottom of the sea.

Li Xuan first tried to swim around the bottom of the sea.

The sea water is a little deep, and even wearing a diving suit, the ears are a little tingling under the action of the pressure.

But fortunately, it can bear it. After adapting for a period of time, this pressure can be ignored.

Li Xuan suspended above the coral reef motionlessly, slowly adapting to changes in water pressure.

The octopus clone didn't care so much, it felt like home when it arrived here, with six tentacles dancing, two tentacles wrapped with sharp knives and military thorns, swaggeringly shuttled across the bottom of the coral reef.

In the coral reef, Li Xuan didn't like those ordinary colorful small fish.

The main targets of the octopus clone are those big crabs and various lobsters that are also domineering on the bottom of the coral reef.

The octopus clone looks quite small, but in fact its body is very resilient, and it can swim in even small places, making it extremely suitable for hunting in this sea area.

Li Xuan controls the octopus clone and shuttles among the colorful coral reefs on the seabed.

A coral reef is originally a structure formed by animals of the order stony corals, which can be large enough to affect the physical and ecological conditions of its surrounding environment.

Coral reefs exist in both deep and shallow seas, and they are formed during hundreds to thousands of years of growth by the skeletons of thousands of coral polyps composed of calcium carbonate.

Coral reefs provide habitat for many plants and animals, including worms, mollusks, sponges, echinoderms and crustaceans.

In addition, coral reefs are also the breeding grounds for juvenile fish of oceanic fish.

Li Xuan also knows that coral reefs are rich in oil and gas resources.

Coral reefs and their lagoon sediments contain a large number of polymetallic strata-bound deposits such as coal, bauxite, manganese ore, and phosphate rock.

Coral limestone can be used as raw materials for burnt lime and cement, and various corals can be used as decorative handicrafts. Many reef areas have been opened up as tourist places.

According to the relationship between the reef body and the coastline, Darwin divided the reefs into shore reefs, barrier reefs and atolls, and divided them into types such as platform reefs and point reefs according to their shapes.

Shore reefs grow and develop along the shores of continents or islands, also known as skirt reefs or fringe reefs.

These coral reefs of various sizes and shapes are inseparable from the health of the earth.

According to statistics, coral reefs support a quarter of all marine species, as well as a billion people, and are an essential part of the ecosystem

The octopus swims among these coral reefs separately, and Li Xuan soon discovers a large number of marine fish.

Most of these sea fish are brightly colored and colorful fish.

Li Xuan looked at it and found it pleasing to the eye.

This is a paradise for fish, which in turn adorn the beauty of the Coral Sea.

Li Xuan, who was floating above the coral reef, had a panoramic view of the entire coral reef, as if he was looking at a crystal clear gem that exudes colorful brilliance.

Look at those beautiful corals.

Look at those beautiful fishes.

Li Xuan opened his arms involuntarily, intoxicated by it.

This sea area is really beautiful.

Presumably the ancients said that those who manage world affairs look at the peak and rest their minds, and they are talking about such a beautiful scenery.

"what."

Suddenly Li Xuan let out a sound of surprise.

It is an octopus clone swimming at the bottom of the coral reef, and a new discovery has been made.

Among the large piles of coral carcasses, the octopus clone saw living coral polyps.

This is a very low-level marine animal, and it is hunting.

Li Xuan found that the appearance of the coral polyp eating was very interesting, like a pitcher plant, with its mouth wide open, waiting motionlessly.

When a plankton happened to swim into the mouth of the coral polyp, the coral polyp closed its mouth immediately, and after a while, when the plankton was spit out again, there were only some food residues left.

Li Xuan smiled slightly, and hurried down to take pictures of this scene with his underwater camera.

Although Li Xuan has known for a long time that coral is actually a kind of marine animal, it is still a very fresh scene to see coral polyps preying on them.

After taking the photos, Li Xuan fell into deep thought as he looked at the massive coral reefs in front of him.

This appears to be staghorn coral.

The origin of the name of staghorn coral is that the corals of this genus have branched growth forms like staghorn, and are one of the most common corals.

The price of staghorn corals of different qualities varies greatly.

Its average quality is worthless at all, and if it is caught, it is just a toy for children to play with.

The most precious ones are national treasures, and every gram is worth more than gold.

Of course, whether these corals are valuable or not has nothing to do with Li Xuan.

At present, the more expensive corals in China are basically not allowed to be salvaged, and they can only be salvaged in the high seas or abroad.

What really made Li Xuan ponder was that he remembered some information about staghorn coral.

It is said that staghorn coral reproduces very fast. Like cells, it reproduces by dividing and dividing. It may float in the water and reproduce a group of small coral polyps at once.

Li Xuan looked at the large number of staghorn corals in front of him and nodded secretly. It seems that the information is true. Only with such a strong reproductive ability can such a large coral reef sea area be accumulated over thousands of years.

Of course, not all coral polyps divide and reproduce after customs clearance. In that case, this planet would have become a coral planet long ago.

And only the coral containing calcareous matter in the body can become the original structure foundation of the coral reef, and other coral polyps cannot build reefs.

Li Xuan remembered the materials he had learned in school.

It is said that the largest coral reef group in the world is the Great Reef Barrier located in the northeast of Australia. It is 20 square kilometers in size and much larger than many prefecture-level cities. There are more than 600 coral reef islands out of the sea in total. Some islands are It even grows in dense virgin jungle.

Look at the coral polyp that is hunting in front of you.

It's really unbelievable that just these inconspicuous little bugs and corpses piled up can form such a magnificent coral island.

After watching it for a while, Li Xuan glanced not far away.

"Ok?"

Suddenly Li Xuan was stunned again. There, there was a very huge and strong dark blue fish, which was frightening just looking at it, swimming towards Li Xuan leisurely.

Li Xuan stared at the big dark blue fish.

That big fish weighed at least a few dozen catties, and was nearly one meter long. Its body was almost no thinner than Li Xuan's. It had striped stripes on its body. Those stripes were like half-full stripes. They were particularly obvious and the colors were very bright. .

Even the face has unique and strange markings. Those markings are like ancient and mysterious charms, which look very hideous and terrifying.

But Li Xuan didn't mean to retreat to avoid it, it wasn't that the fish was swimming too fast, Li Xuan didn't have time to avoid it.

But Li Xuan knew that it was a gentle sea fish that would play with divers in the coral.
