The Australian box jellyfish, also known as the "sea wasp", "death fairy", can be as many as 60 jellyfish whiskers the size of a salad bowl, each of which is 4.6 meters long. Each tentacle has 5000 stinging cells and enough toxins to kill 60 people, so they are also known as transparent killers in the ocean. Worst of all, the deadly jellyfish is said to attack humans on its own initiative. The Australian box-shaped jellyfish "shoots" the relaxed 1-meter-long antennae 3 meters away, entrapping swimmers, and venom blocks the breath. If you swim in the sea unfortunately caught by the lamp jellyfish's weapon (tentacles), it's like being beaten at the same time by dozens of red whips.
The box jellyfish has 24 eyes on the bell body. In one group, two were advanced and complex eyes, and four were photosensitive primordial eyes.
Box jellyfish is the world's most toxic jellyfish, one of the world's most toxic marine life, ten deadly animals ranked third. Once a man is stabbed by his tentacles, he will die within three minutes. In Australia's Queensland coast, about 60 people have been killed in 25 years as a result of mid-box jellyfish poisoning, but at the same time only 13 have died from shark belly.
The only way a mother can avoid being attacked by a sea wasp is to avoid swimming in the jellyfish's infested waters. There are warning signs on all beaches in northeastern Australia to remind people of the jellyfish. Scientists are trying to find more effective antidotes and ways to prevent their attacks.
A box of jellyfish toxin enough to poison 60 adults, if the box of jellyfish poison, 0 seconds to 4 minutes without treatment, will die. The Australian box jellyfish is a light blue transparent jellyfish shaped like a box with four distinct sides each 20 centimeters long. The box jellyfish has 60 3-meter-long tentacles, with billions of poison bags and needles on them, enough to kill 20 people. The tentacles are densely covered with spiny cells, stinging cells and sacs containing venom. Once the tiny fish and shrimp touch the tentacles, the cells on the tentacles will stab the deadly poison into the body of the prey and inject the venom into the prey, causing it to die of poisoning. The tentacles then curled up and sent their prey into the jellyfish's mouth. There are also receptors on its tentacles that recognize proteins on the skin of fish, shrimps or human beings. When the tank jellyfish finds its prey, it quickly floats past, snuggles it with its tentacles, and immediately injects the poison with a needle. Once the venom is sprayed on the body, many bright red wounds appear immediately on the skin. The venom quickly invades the human heart and can cause death in just two or three minutes, even without the time for rescue.
It is not clear why the tank jellyfish is so toxic, but researchers have found that its main poison is the heart. A healthy person's heart has millions of muscle cells that beat at the same pace. When the venom of the jellyfish invades the human heart, it destroys the consistency of the beat rhythm of the muscle cells, which causes the heart to fail to supply blood normally, leading to the rapid death of the human body. The study also found that acetic acid can kill the tentacles of jellyfish, so scientists suggest that tourists who go swimming and dive in Queensland should take a bottle of vinegar for use when they encounter a tank jellyfish. However, scientists are analysing the structure of the tank jellyfish venom in the hope that it will produce a cure to avoid further deaths from the tank jellyfish.
The American Journal of World Wildlife lists the ten most toxic animals in the world, with jellyfish living in the ocean at the top of the list. Through the United Kingdom, Australia, the Soviet Union, the United States, France, Italy, Scientists from 19 countries, including Japan, have identified 10 species of animals as "world poison kings" as follows:
1. Australian box jellyfish (or Australian box jellyfish): living off the coast of Australia, people who touch their tentacles will die in 30 seconds.
Aketherin Sea Snake, Australia: it has a big mouth and lives in the same waters as the Australian tank jellyfish.
3. Australian Blue Ring octopus: this mollusk is only 15 centimeters long and has a blue link on its wrist and foot and is often found in Australian coastal waters.
4, poisonous fish by: live in the coastal waters of Australia.
Palestinian scorpion: live in Israel and other parts of the far East.
Australian funnel-shaped spider: lives on the outskirts of Sydney, Australia.
7, Australasian Taibana serpent.
8, Australian brown reticulated snake.
9, King Cobra.
10, African Black Manga Snake.
