"These leatherback turtles are our Maldives' model workers. They will work diligently to help us clear jellyfish in the waters near the Maldives islands."

The coach proudly explained to Xi Ming and Xia Ritian.

"Jellyfish look so beautiful and gentle. These turtles eat them... It seems to be a cruel feeling. The sweet and kind heart in summer feels very disliked by those big turtles."

People always sympathize with the weak, but sometimes natural laws tell us that it is not like that.

Seeing that everyone was not happy with sea turtles, a coach said on the bottom of the water with a vibrating intercom, "Haha, that's why you don't know the advantages of jellyfish. Although jellyfish look beautiful and docile, they are actually very ferocious. Under the jellyfish umbrella-shaped bodies, those slender tentacles are their digestive organs and their weapons. The tentacles are covered with thorn cells, like poisonous silk, and can ejaculate venom. After the prey is stinged, they will quickly paralyze and die."

"Ah, that's so terrifying."

Xia Ritian was obviously shocked by the coach's explanation.

"Yes, the tentacles of jellyfish hold these prey tightly, retract, and suck it with the polyps under the umbrella. Each polyp can secrete enzymes and quickly decompose the proteins in the prey. Because jellyfish have no respiratory organs and circulatory systems, only the original digestive organs, so the captured food is immediately digested and absorbed in the coelenterology."

"Most jellyfish live in stagnant areas, and their lives are extremely tenacious. It almost requires oxygen. Therefore, you will find that it is also in the deep sea area of ​​several thousand meters. The appearance of jellyfish is not a phenomenon of environmental improvement, but a manifestation of environmental deterioration. With the serious water pollution, abundant nutrients, and a large number of catastrophic plankton appearing, resulting in a large number of fish deaths, but jellyfish begins to flourish, but this is the prelude to another disaster. Jellyfish eats everything, plankton, fish eggs, small fish, and big fish ~ none of them miss the net. Its prosperity makes it difficult for fish to regenerate, and the consequences will be irrecoverable!"

"The body of the jellyfish looks like a transparent umbrella, and the diameter of the umbrella is large and small. The umbrella of an ordinary jellyfish is not very large, only 20 to 30 cm long, while the umbrella of a large jellyfish can reach 2 meters in diameter. Some whisker-like strips grow from the edge of the umbrella. This kind of strip is called tentacles. Some tentacles can be as long as 20 to 30 meters, which is equivalent to the length of a large whale.

"At the beach, in the hot summer, when someone is swimming in the beach, sometimes he will suddenly feel a sting of pain in the front chest, back or limbs of his body, just like being beaten by a whip. It is definitely a jellyfish that is stinging people again. However, usually when being stabbed by a jellyfish, it will only feel scorching and redness and swelling. Just apply anti-inflammatory drugs or eating vinegar, which can relieve swelling and pain in a few days. However, some jellyfish, such as killer jellyfish and sea bee jellyfish, secrete strong toxicity. If they are stabbed by them, they will have difficulty breathing within a few minutes. At this time, artificial respiration or inject cardiotropic agents, otherwise they will have to hang up. This is also the reason why we recommend that you wear diving suits to prevent being stung by poisonous jellyfish..."

"Jellyfish are really that dangerous."

"Yes, it's very dangerous. Jellyfish are definitely more dangerous than you think. Most jellyfish never let go of prey once they encounter prey. If the mighty and deadly jellyfish are like this, then humans are also quite dangerous. However, no matter how powerful jellyfish is, they have natural enemies in our Maldives, which are the leatherback turtles we just saw. They can freely shuttle through the group of jellyfish, easily pulling off their tentacles with their mouths, making them only roll up and down, and finally lose their resistance, becoming a "good meal" for sea turtles.

Because there is a special substance in the gastric juice of turtles that can resolve the extremely toxicity of jellyfish, it can eat jellyfish."

...

Always.

Our Maldives has its natural enemy, leatherback turtles. They shuttle freely in the jellyfish group and easily pull off their tentacles with their mouths, making them only roll up and down, and finally lose their resistance, becoming a "good meal" for sea turtles. In the gastric juice of sea turtles, there is a special substance that can resolve the extremely toxicity of jellyfish, so it can eat jellyfish.

So leatherback turtles are our patron genius and model workers!

This thing that looks gentle in the ocean is the most dangerous creature, and the huge thing that looks domineering and inaccessible is the guardian of human beings... Nature has taught everyone a magical lesson.

The group of big sea turtles first created some tension for everyone, and then the jellyfish made people wary again.

When the turtle leaves completely.

Immediately afterwards.

Other colorful fishes in this area of ​​water also appeared in front of everyone.

I felt the colorful fish swimming around me freely, with the clear blue and clear light spots on the water, making everything look so beautiful and dreamy.

Xi Ming couldn't help but erupt in his heart.

Blue sky

The sea

This generous embrace

Hold me gently

Constantly light, constantly thin

Fish are flying

Colorful slutty

Coral sways

Colorful and colorful posture

I'm drunk

In this swaying blue romance.

Some people say that the moment you dive into the water, you will know why you love the sea. In the sea, you can experience a kind of freedom, stretch, and your body and mind seem to be penetrated by the sunlight, unrestrained, unrestrained, and devoted to nature.

At this time, a trainer underwater, Ximing, specially arranged it to specialize in catching the sweet summer in the water and swimming in the fish, as well as beautiful photos of enjoying the coral scenery.

"Please see, these corals are not plants, they are actually animals, and the main body of these coral reefs is also composed of coral polyps. Coral polyps are a kind of coelenteric animal in the ocean. They feed on preying on tiny plankton in the ocean. During their growth, they can absorb calcium and carbon dioxide in the seawater, and then secrete limestone, which becomes the shell for their own survival."

"Each monomer polyps are only the size of rice grains. They live together in groups, metabolizing, growing and reproducing from generation to generation, and secreting limestones continuously and bonding together. These limestones are compacted and petrified later to form islands and reefs, which are the so-called coral reefs. Because of the adhesion of coral polyps, many coral reefs often have a large number of coral polyps attached to the bottom of many coral reefs."

Xi Ming felt that this inland boy was gaining knowledge and swaying. He used to think corals were plants, but he didn't expect corals to be animals.

OK, my hair is short…”

At this time, the sun was shining and snorkeling in the sea. Ximing followed the coach's guidance and looked at the colorful and particularly beautiful scenes of coral polyps preying on the ground.

There are many small holes in the middle of the coral reef, and coral fish are constantly swimming in and out of those small holes. There are many types of coral fish, including colorful, long, short, round, triangular and other fish.
