However, I have striped circulatory muscle tissue that can move and retract. I do not have specialized respiratory organs and rely on my skin and mouth to absorb oxygen.

Many jellyfish like me will glow. When I shine, my whole body seems to turn into a dazzling colored ball. At the same time, my transparent hands will also shine with light, just like the fine lines on the colored ball. band of light. These light strips will sway left and right as soon as you swim. Against the blue light, they are very charming.

As far as I know, you humans say that we jellyfish glow differently than other animals. We don’t have a luminescent system. My luminescence relies entirely on a wonderful protein called equine, which emits blue light when it encounters calcium ions. The more Aquilin there are, the stronger the light shines.

My hunting skills are also very good. My hands are poisonous. As long as it stretches out its tentacles, even the softest jellyfish will immediately transform into a terrifying predator. On the skin of my hands, there are special cells called "nematode sacs". These sacs contain terrible venom and microorganisms! !

I watched the jellyfish's thin and long little feet floating around with their bodies. I really wanted to count how many little feet they had, but it's a pity that my eyesight is not that good. When I was about to turn around and leave, I was shocked when the surrounding area was full of jellyfish, which made me dazzled. It even has the Hoi Chi Tou that we had in the hotel!

I heard that a "Jellyfish Undersea Park" has opened. The advertisement said: "Everyone, come to the Jellyfish Park. You can choose from fun, beautiful, and funny things!!" Half of the adults didn't believe it, but most of the children However, they clung to the advertisement like a magnet: "I have to go, I have to go.

I saw the information about infected jellyfish clearly. It’s the most polite thing to do when you find an infected jellyfish, but…. "Haha, if you are weak, I will be strong.

The crystal clear jellyfish became colorful as the light changed, which was dazzling and very beautiful. Got it!

Each jellyfish has a semicircular head, and some are dragging long "braids", like colorful mushrooms swimming in the water, and like holding a handful of Beautiful little fairies parachuting down to earth; they are also highly skilled dancers, stretching their limbs in the water to perform light and graceful dances.

Jellyfish are lower creatures. They have neither eyes nor noses. They eat and excrete through the same outlet. But they can feel the storm coming more than ten hours before it hits! This is because there is a small ball on the thin handle in the middle of the jellyfish tentacles, with a small listening stone inside, which is the "ear" of the jellyfish. The infrasound waves generated by the friction between waves and air impact the listening stones and stimulate the nerves of the jellyfish, so that the jellyfish can feel it more than ten hours before the storm comes and disappear from the sea surface.

I have been to Sea World twice and saw many marine life that I have never seen before. in. What impressed me most was the elegant jellyfish. The transparent body of the jellyfish is covered with tentacles, which are dancing as if trying to catch something. The umbrella-shaped body swims in the fish tank, making the fish tank full of fairy tale colors.

Later, when I went home and looked up information, I learned that the main component of jellyfish’s body is water. The water content in its body can generally reach more than 97%. Most of their lifespans are only a few weeks, and some are still alive. To about a year, some deep-water jellyfish can live longer.

After reading the information, I couldn't help but fall into deep thought: How do such "weak" jellyfish survive the terrible storms in the sea? It turns out that jellyfish have a "special function" that is different from other animals. That's the ability to predict storms. There is a small ball on the thin handle in the middle of the jellyfish tentacle, with a small listening stone inside, which is the "ear" of the jellyfish. The infrasound waves generated by the friction between waves and air impact the hearing stones and stimulate the surrounding nerve receptors, allowing the jellyfish to obtain information more than ten hours before the storm arrives. Therefore, they seem to have received some order from the sea " "Suddenly" they all disappeared.

Scientists once conducted experiments by simulating the sound wave transmitting organs of jellyfish, and found that they could detect ocean storm information fifteen hours in advance, so they invented the "jellyfish storm predictor" based on this principle. The "Jellyfish Storm Predictor" can predict ocean storms in advance and is widely used in fisheries, tourism, and even the military.

Nature is like a knowledgeable teacher who can teach humans endless knowledge. If we learn from nature, we will benefit a lot.

Essay about jellyfish 8

They appeared earlier than the dinosaurs and can be traced back to 650 million. years ago. The body of a jellyfish is mainly made of water, and its body water content reaches 99%, so it is transparent.

Although jellyfish look beautiful and docile, they are actually very ferocious and are carnivores. Under the umbrella, those slender tentacles are its digestive organs and also its weapons. There are many stinging cells on those tentacles, which are like poisonous threads and can shoot venom, which will quickly paralyze the prey and kill it.

After more than ten days, my jellyfish died. My father said that maybe the water was too hot and the jellyfish couldn't stand it and died and turned into water. There is also the possibility that the changed water quality may lead to the death of jellyfish.
