My Deep-sea Fishery

, The fastest update of the latest chapter of my deep-sea fishery!

Xiang Yang swam to the silt-laden sea area, almost to the bottom of this submarine slope, and the seawater was more than a hundred meters deep.

On this muddy ground, Xiang Yang could not see any other marine life except for some scallops and mussel shells.

It's not that there are fewer marine animals under the ocean at this depth. Even at a depth of 10,000 meters, there are many marine creatures living under the ocean.

In the process of human exploration of the ocean, someone once explored a depth of 10,911 meters. Under such a deep seabed, the entire seabed is pitch black, with an average water temperature of only 2 degrees Celsius, while some of the seabed water temperature that heats up due to crustal movement is as high as 380 degrees Celsius. Under such extreme environments, there are still marine organisms. Those strange creatures are not only heat-resistant, but also pressure-resistant.

Scientists have calculated through precise calculations that the huge water pressure on the seabed at a depth of 10,000 meters can instantly crush the human body into a meatloaf. All of these have created a strong attraction to scientists, and human exploration of the ocean has never stopped. .

The reason why marine animals are scarce in this sea area is really because the bottom of this sea area is too barren, the seabed is full of silt, and even the aquatic plants are very scarce.

"Huh, wait."

When Xiang Yang hovered over the silt-covered sea and looked around, he suddenly saw a lush green in one direction.

Xiang Yang wondered, "Could it be an undersea jungle?"

When it comes to the ocean, people usually think of marine animals that are lively and cute or ferocious, while plants think that there are only corals.

In fact, corals are not plants.

As an important part of the marine ecological environment, marine plants are the most indispensable in the entire marine ecosystem.

If there are no marine plants in the sea, the entire ocean will lose its vitality and beauty. Plants provide oxygen to animals, and animals provide nutrients to plants. Together, they form the entire marine biosphere, and the two are interdependent.

Xiang Yang swam towards the lush green sea.

The first thing that reflects Xiang Yang's eyelids is a small algae that can't be seen at a glance.

Algae themselves are the most diverse marine plants in the ocean. Xiang Yang is not surprised to see algae. The most common kelp and seaweed in our lives are all algae.

Algae can not only be made into a variety of nutritious delicacies, but also can be processed and refined into a variety of medical drugs for the treatment of various diseases.

Xiang Yang slowed down and swam vigilantly above the algae clump.

This kind of algae looks very strange, a bit like a leaf-like plant, with small leaves and a shape similar to vines on land.

"This should be a kind of benthic algae." Xiang Yang silently raised his head and looked at the top. The top was pitch black. He didn't know how far away there was a faint blue light. He suddenly felt very magical, under such a deep ocean. There is almost no way for plants to carry out photosynthesis, but these algae grow like this, and they grow lush.

However, Xiang Yang knows that the water body has a strong ability to absorb light, and sea water absorbs long-wave light very easily. Although there will be huge differences in the spectrum of each water layer with different water depths, in general, even in light In the deep sea that cannot be illuminated, algae are generally capable of photosynthesis.

Turning around under this sea area, Xiang Yang found a crab with small spikes on its back shell.

But Xiang Yang didn't bother to catch these crabs.

These crabs swim fast under the water. How can there be mussel shells that hardly move to catch?

And those clam shells are more expensive than these crabs.

Xiang Yang searched carefully in this seaweed cluster for a while before going back to the location of the silt.

At this moment, Xiang Yang's eyes condensed, and he saw a group of behemoths.

Under the cover of the abundant seaweed bushes, the behemoths are hiding at the bottom of this sea area.

The group of creatures that Xiang Yang observed carefully, their body length is about 3 meters, they have thin and short body hair, no backs, and no necks. The very bloated body is directly in front of a head, which looks very round. It's cute, it's chubby all over, and you can't see the slightest point of water chestnut.

Xiang Yang is observing them, and they are also observing Xiang Yang.

Even though they don't have necks, they can turn their heads. They are lying in the seaweed and turning their heads quietly to observe Xiang Yang.

"It's actually a dugong." Xiang Yang was amazed. The dugong and the manatee are close relatives, and it can also be regarded as a kind of manatee, a mammal similar to a whale.

Dugongs used to live on land and are said to have the same ancestor as Asian elephants. They came to the ocean and began to live about 25 million years ago.

Dugongs have a very wide range of branches. They are likely to be seen in the Indian Ocean and the Pacific Ocean. They like warm waters and often cover themselves with lush seagrass. They are the only kind of herbivorous mammals in the ocean. .

The group of dugongs in front of them has a total of five heads, two big ones, one half big and two small ones.

Xiang Yang tried to swim towards the group of dugongs. He wanted to take a closer look at the group of dugongs. Dugongs were more docile than dolphins, and he didn't worry that he would be attacked if he swam rashly.

Xiang Yang went there.

The group of dugongs retreated immediately, very alert to Xiang Yang.

Xiang Yang stopped immediately. In addition to being docile, the dugong was also timid, and if he was frightened a little, he would immediately be frightened and flee.

Speaking of Fleeing Yaoyao, Xiang Yang remembered something very interesting.

That is, dugongs like whales ~www.readwn.com~ also like to sing very much.

In summer, dugongs often sing on the rocks on the coast.

Sometimes fishermen on the beach are attracted by the dugong's singing, and they will run over to watch.

As a result, as soon as the fishermen approach, the cowardly dugong will immediately escape. Generally, the fishermen can only see a wave of water and there is no dugong.

So in ancient times, fishermen mistook the mysterious singing creature for a mermaid, a mermaid with a human upper body and a fish lower body, and spread the legend of the mermaid.

Xiang Yang stood still, and the dugongs who were retreating in fear settled down a little, but still looked at Xiang Yang vigilantly.

Xiang Yang guessed that they must have been frightened by him, because they must have never seen a creature like himself on the seabed before.

Although Xiang Yang knew that if he really wanted to swim past, these dugongs would certainly not be able to swim faster than himself, but looking at these guys with a frightened look, Xiang Yang didn't intend to swim further.
