Is jellyfish poisonous?

Jellyfish is poisonous. Jellyfish venom can cause different degrees of damage after stinging the human body, such as sea wasp jellyfish, stinging silk can secrete cobra venom, which is the most harmful to human beings, and can cause death 5 minutes after jellyfish injury. The monk hat jellyfish contains a "hypnotoxin", which is made up of peptides and proteins and small molecules containing nitrogen. It takes many days for the patient to relieve the pain after stinging the body. Along the coast of China, there are common sand sea stings floating in the Yellow Sea with the cold current, which can secrete peptide poison. Jellyfish toxin is stored and distributed in the barbed silk sac. 1 gram of jellyfish toxin contains 55 million single thorn silk sacs. Generally, after fishing, the toxicity of jellyfish toxin can disappear quickly after processing.

Symptoms of jellyfish poisoning

The thin and tender part of the human skin is the most prone to stinging. Generally, the electric shock-like tingling sensation can occur in a few minutes, and the electric shock-like tingling sensation gradually appears in the injured area after a few hours. After a few hours, the injured area gradually appears a blood rash with erythema arranged in line, itching and burning pain. The mild one can heal itself in about 20 days. Patients with strong sensitivity may have erythema edema, wind masses, blisters, ecchymosis, and even epidermal necrosis. The patient's whole body performance may have restlessness, chills, abdominal pain, diarrhea, low spirits and chest tightness and shortness of breath. Severe cases often have cough and asthma attacks, spitting white or pink foamed sputum, accompanied by signs of anaphylactic shock, such as weakness of pulse, cyanosis of skin and decrease of blood pressure. If the rescue is not timely, patients with this kind of sting can die in a short period of time.

The most poisonous jellyfish

The square jellyfish is considered to be the deadliest jellyfish. None of the most poisonous jellyfish are called "sea wasps", which can kill people. These small (less than 20cm in diameter), translucent guys are very dangerous to touch. Toxic, difficult to find in the water, swimming speed is very fast (more than 4 km / h). Square jellyfish live in tropical waters, mostly in the shallow waters of Australia Bay, swimming to the beach when the wind is calm. If someone touches the tiny cells in the square jellyfish, they may die quickly. Off the coast of Queensland, Australia, about 60 people have been killed by Chinese jellyfish poisoning in the past 25 years, while only 13 have died in the belly of sharks.

Cases of jellyfish poisoning

On July 29, 1987, strong winds blew a large number of jellyfish into the Beidaihe beach. Jellyfish's long tentacles are like a girl's hair, and its round "head" is as lovely as beautiful jade. Swimming in a shrinking manner is even more chic and moving. Many bathers are confused by it and use their hands to grab it and hug it. However, it was in this "intimate hug" that more than 600 people were stung, and a young woman named Li Yunfen was so poisoned that she died after emergency treatment.

On August 11, 2014, men and friends traveling from Mudanjiang to Dalian visited Xinghai Bay Bath. When he heard the cry for help at the seaside, he found that it was a girl with a big jellyfish beside her, which was as big as an open tent. He bravely pushed the jellyfish away, but he was jellyfish. That night, the man died without rescue.

Note: never catch or touch jellyfish floating in the sea. Once you are injured by jellyfish, do not rinse with fresh water, because fresh water can prompt stinging cells to release venom. Wipe the tentacles or venom attached to the skin with towels, clothes and sand as soon as possible, and wash the injured area with sodium bicarbonate (baking soda) or alum. If the injury area is large and the systemic reaction is serious, you should go to the hospital for treatment in time.
