My Deep-sea Fishery

Xiang Yang swam to the muddy sea, almost reaching the bottom of the seabed slope, the seawater was already more than 100 meters deep.

Except for some scallops and mussel shells, Xiang Yang basically saw no other marine life on this muddy ground.

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

In the process of human beings exploring the ocean, someone once probed the deep sea of ​​10,911 meters. Under such a deep sea, the whole seabed is dark, and the average water temperature is only 2 degrees Celsius. However, some seabed waters that are heated due to crustal movement have a temperature as high as 380 degrees Celsius. There are still marine organisms living in such an extreme environment, and those strange creatures are not only resistant to heat, but also resistant to pressure.

After precise calculations, scientists concluded that the huge water pressure on the seabed at a depth of 10,000 meters can instantly crush the human body into a meatloaf. .

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

"Hey, wait a minute."

When Xiang Yang was hovering above the silt-covered sea and looking around, he suddenly saw a lush green in one direction.

Xiang Yang was puzzled, "Could it be the underwater jungle?"

When it comes to the ocean, people generally think of those lively and cute or fierce marine animals first, while plants only think of corals.

Corals are not actually 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 constitute the entire marine biosphere, and the two are interdependent.

Xiang Yang swam towards the lush green sea area.

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

Algae itself is the most diverse marine plant 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 over the patch of algae.

This algae looks very strange, a bit like a leafy plant with small leaves, and its shape is a bit similar to vines on land.

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

However, Xiang Yang knows that water bodies have a strong ability to absorb light, and seawater 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 the light In the deep sea that is not exposed to sunlight, algae are generally capable of photosynthesis.

Turning around in this sea area, Xiang Yang found a kind of crab with tiny spikes on its back shell.

But Xiang Yang was too lazy to catch these crabs.

These crabs swim fast at the bottom of the water, how can there be clam shells that hardly move?

And those shells are more expensive than these crabs.

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

At this moment, Xiang Yang's eyes were fixed, and he saw a group of huge monsters.

The group of huge monsters are hiding at the bottom of this sea area under the cover of the abundant seaweed bushes.

The group of creatures that Xiang Yang observed carefully, they are about 3 meters long, with thin and short body hair, no back, no neck, and a head directly in front of the very bloated body, which looks very round Cute, round and round all over, without the slightest distinct parts of water chestnut.

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

Don't look at them without necks, but their heads can turn. They are lying on the seaweed and turning their heads quietly to observe Xiang Yang.

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

Dugongs used to live on land. It is said that they have the same ancestor as the Asian elephant. About 25 million years ago, they came to the sea and began to live.

Dugongs have a wide range of divisions, and they may be seen in various seas in the Indian Ocean and the Pacific Ocean. They like warm waters and often cover themselves with lush seaweed. They are the only herbivorous mammals in the ocean. .

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

Xiang Yang tried to swim towards the group of dugongs, he wanted to have a closer look at the group of dugongs, dugongs are more docile than dolphins, so he wasn't worried that he would be attacked if he swam there rashly.

Xiang Yang went there for a swim.

The group of dugongs retreated immediately, very wary of Xiang Yang.

Xiang Yang stopped his body immediately, besides being docile, the dugong was also timid by nature, if he was frightened a little, he would immediately run away in fright.

Speaking of running away, Xiang Yang thought of a very interesting thing.

That is, dugongs, like whales, also like to sing very much.

In summer, dugongs often stay on the reefs by the coast and sing.

Sometimes fishermen by the sea are attracted by the singing of dugongs, and they will run to see them.

As a result, as soon as the fishermen approached, the cowardly dugong would run away immediately. Generally, the fishermen could only see a wave of water without the dugong.

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

Xiang Yang stood still, and the dugongs who retreated in fear calmed down a little, but they 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 him on the bottom of the sea before.

Although Xiang Yang knew that if he really wanted to swim over, these dugongs would definitely not be able to swim faster than him, but looking at the frightened looks of these dugongs, Xiang Yang did not intend to continue swimming forward.
