How does a jellyfish die? What to do with live jellyfish

Jellyfish usually live alone, floating or swimming, and a very small number of species live in groups, and some groups can live in sedentary groups. Even if it is boiled in water, it is dead, and the cold jellyfish we usually see is.

Hello! Before the death of the sea stinger, if the reaction is slight when touched with an object (generally it will move quickly after touching), the body cavity part of the dead sea stinger will no longer rhythm, and after death, it will begin to melt and become liquid.

Normally, if you put a jellyfish in the seawater, the jellyfish will no longer move, and it will usually be dead, so if you are really not at ease, you can make it into food.

When the jellyfish is cooked, it is certain that it is dead. Because there's no way to be sure how I feel.

Jellyfish, commonly known as jellyfish, stone mirror, wax, barley, catfish, jellyfish and sea (insect house zha) and so on. Jellyfish belongs to the class of Jellyfish Bowl, is a kind of coelenteric mollusk living in the sea, the body shape is hemispherical, edible, the upper is umbrella-shaped, white, by telescopic movement, called jellyfish skin, there are eight mouth wrists below, there are filaments under it, gray-red, called jellyfish head.

Jellyfish, also known as jellyfish, is a coelenterate. The head of the jellyfish is in the shape of a steamed bun, with a diameter of about 50 centimeters, and the largest can reach 1.5 meters, which is relatively hard and usually blue. If we pinch the jellyfish and see if it moves, it should be alive.

To not move is to die.

When it is cooked, it can be concluded that it must be dead. Haha, that's how it should be

This situation belongs to the jellyfish dermatitis after the jellyfish sting, the tentacles of the jellyfish have a large number of cnidosis, the cnidids contain venom, and their components are mainly protein-likes, peptides and a variety of toxic enzymes, which can be pierced into **, which will cause cnidial dermatitis. In this case, it can not be washed with fresh water, use alkaline solution to apply cold compress to the sting site, and use antihistamines such as chlorpheniramine to have a certain effect, don't worry, so it will be fine.

If the jellyfish is dead, why does he still know about people? It's impossible.

Poisonous. Fresh jellyfish contains more water, the skin is thicker, and it also contains toxins, which is not suitable for consumption, and needs to be salted with edible salt and alum for 3 times (commonly known as alum), so that the fresh jellyfish can be dehydrated 3 times before the toxins can be drained with the water.

The glyptocyst of fresh jellyfish contains venom, and its toxin is composed of a variety of peptide substances. Jellyfish toxin is 450 times more toxic than tetrodotoxin. Jellyfish rely on the filament sac on the tentacle to protect itself, and when the tentacle touches a person, it will wrap around it, and at the same time, the filament pops out of the sac, pierces into the human body, and releases peptide toxins, which is the way the jellyfish protects itself.

When a person tears off the tentacle, it still sticks to the wound and continues to release poison.

Jellyfish can sting whether they are alive or dead, or even if they break into pieces and wash up on the beach.

Wash fresh jellyfish with clean water first, and be aware that jellyfish will sting;

Then put the fresh jellyfish in fresh water, soak the jellyfish for two days, then remove and rinse well;

Soak in vinegar for more than 5 minutes. Remember that it takes more than 5 minutes. Note that jellyfish should be soaked in vinegar for a longer period of time so that all solitary bacteria are killed.

1.First, spread the jellyfish skin on the table, cut it into thin strips with a knife (the filaments should not be too thin and thick, about 2 cm wide and about 5 cm long), then put it in a large basin, pour cold water, rub it gently with your hands for a while, take it out, and then put it in a basin and soak it in cold water for 8 to 10 hours. During this time, it is best to rub three to four times, change the water each time, and rub.

After rubbing, soak in cold water. This kind of scrubbing and soaking can be said to kill two birds with one stone, which not only washes away impurities such as sand in the jellyfish skin, but also cleans the salt and alum on the jellyfish skin, and removes the bitter and salty taste of salt and alum. If you eat improperly washed jellyfish skin, you may experience symptoms such as diarrhea and vomiting.

2.The soaked jellyfish skin tastes neither astringent nor salty, and has a faint feeling. If there is still a salty taste, it means that the soaking time is not enough or the washing is not clean.

At this time, don't rush to enjoy. Continue soaking and rubbing according to the first method until there is no astringency and saltiness.

3.Bring the water in the pot to a boil and quickly pour the soaked jellyfish skin into the boiling water. Blanch in boiling water for too long, basically it is done in 20 seconds, and then take it out and immediately soak it in cold boiled water to cool.

If the blanching time is not well controlled, the jellyfish skin will shrink sharply, affecting the taste. According to this method, the jellyfish skin is fully expanded, tender and refreshing, and the cold salad does not lose its original flavor.

4.Jellyfish skins are mainly eaten in cold salads. Cold salad must be vinegared. Aged vinegar is preferred. Seasonings such as salt, monosodium glutamate, etc., mainly suit your taste.

5.The black, smelly jellyfish skin may have gone bad, so don't eat it to avoid eating it badly.

The spoiled jellyfish is cloudy in color, soft in flesh, and has a fishy smell; Spoiled jellyfish are transparent, odorless, and tough, and are not easy to tear off when gently pulled by hand, and when they are fished out of the water and put for a while, they will be as soft as scotch tape.

Fresh jellyfish is crystal clear, the meat is thick and elastic, smell a fresh seafishy smell, look white with yellow, high-quality jellyfish silk is white or light yellow, colored, no red spots and sediment, spread out the jellyfish silk, the bigger and whiter and thinner the better, its meat is brittle, not hard, not broken, crisp to eat, chewy.

Jellyfish are poisonous. Jellyfish is a marine coelenterate, the stinging body is umbrella-shaped, translucent, white, cyan or yellowish, can secrete venom, its function is to release venom paralysis when touching small animals, to make food.

Jellyfish can be eaten, jellyfish toxin is stored and distributed in the nematomy, 1 gram of nematocyst contains 55 million single nematocysts, generally after fishing, its toxicity can quickly disappear after processing.
