How jellyfish attack people, how jellyfish sting

Jellyfish emits light thanks to a wonderful protein called Equimin, which emits a strong blue light when mixed with calcium ions. The more the amount of Equimin is in the jellyfish, the stronger the light emitted, and each jellyfish contains only an average of fifty micrograms of this substance. Can't stop there is electricity.

In addition, jellyfish are beautiful and docile, but they are actually very fierce. Underneath the umbrella, those slender tentacles are its digestive organs, as well as its **. The top of the tentacles is covered with stinging cells, like poisonous wires, which can shoot venom, and after the prey is stung, it will quickly paralyze and die.

The tentacles hold these prey tightly, retract them, and suck them up with the polyps underneath the umbrella, each of which is able to secrete enzymes that quickly break down the proteins in the prey. Because jellyfish have no respiratory organs and circulatory system, only primitive digestive organs, the captured food is immediately digested and absorbed in the coelenterum. In the hot summer, when we swim in the tide at the beach, sometimes we suddenly feel a tingling pain in the chest, back or limbs of the body, as if we have been whipped by a leather whip, and it must be a jellyfish stinging again.

However, if you are stung by a jellyfish, you will only feel burning pain and redness, as long as you apply anti-inflammatory drugs or vinegar, it will reduce the swelling and pain in a few days. However, in the sea from Malaysia to Australia, there are two kinds of jellyfish called sea bee jellyfish (box jellyfish) and hand jellyfish, which secrete very poisonous, and if they are stung, they will die within a few minutes, so they are also called killer jellyfish. Therefore, when you are stabbed by a jellyfish and have difficulty breathing, you should immediately implement artificial respiration or inject a cardiotonic agent, and you must not be careless to avoid accidents.

Once a jellyfish encounters its prey, it never lets it go easily. It is possible to give people the false impression that it has electricity!

Jellyfish have stinging cells at the tips of their tentacles, which can still fire stinging cells and inject toxins after the jellyfish dies.

There are tiny stingers on the tentacles, pierced into the ** stab into the venom (the animal begins to die, the vitality is strong, it will leave a scar) people will be nauseous, and other symptoms (give a good review).

The tentacles puncture the surface**, but then inject venom

Jellyfish is a very low animal, often floating on the surface of the sea, drifting with the current, because the body contains more than 95% of the water, so it looks like colorless and transparent, if you touch it with your hands, it will be like touching a caterpillar, it will be stung red and swollen, and the pain is unbearable.

How do jellyfish sting? It turns out that the body of jellyfish is usually divided into two parts, one part is the "umbrella" part that is exposed to the water, and the other part is the mouth and wrist part that is immersed in the water. These tentacles are no small few, and their surface is dotted with countless stinging cells, and inside the stinging cells is a barbed wire that hides venom and a thin tray of barbed wire.

The most terrible jellyfish is the Arctic jellyfish, especially the male jellyfish is very fierce, its "umbrella" diameter is about 2 meters, the lower edge of the "umbrella" has 8 groups of tentacles, each group of 150, and there are countless stinging cells on the tentacles.

Jellyfish toxins are very harmful to the human body, so how do jellyfish sting people?

This is easy to understand!

1. Use a net to fish, because jellyfish are phototaxis like moths, so they can also be fished at night.

2. Jellyfish cannot adapt to water with low salinity, while shrimp can be slightly lower. For example, jellyfish have to eat one catty of salt a day, and less than nine taels will die of "light", while shrimp can't die if they eat half a catty a day. So you feed eight taels of salt a day, so that the jellyfish are starving to death.

That is, add fresh water, reduce the salinity of the breeding pond and kill the jellyfish. However, it is necessary to observe the performance of the shrimp at all times, and if there is any discomfort, quickly recharge the seawater. Then there is that a large number of jellyfish will spoil the water, so it is necessary to change the water in time.

3. Do not channel water between pools to prevent "infection".

They also said that the entrance should be closed, and the seawater that comes in should be treated, or it should be blocked with a net.

You don't have to kill it, jellyfish are seasonal things, they have a short growth cycle, and they will die naturally after a few days.

If you don't have razor clams, you can consider using tea seed cakes.

The tentacles on the jellyfish have poisonous glands that can sting, so don't mess with the jellyfish, some jellyfish are very poisonous.

Most jellyfish will not actively attack humans, but some jellyfish have very long tentacles, the longest is hundreds of meters, once people touch their tentacles will almost be stung, and the toxicity is huge, generally speaking, there is no chance of survival, other poisonous jellyfish are also difficult to find, a little careless touch them will be a miserable thing.

What a lovely question...

His teeth.

It's tentacles that sting...

Jellyfish toxin, the general term for the toxins contained in jellyfish, is a unique and novel mixture of proteins and peptides, with a wide range of activities, hemolysis, antioxidant and other biological activities, with cardiovascular disease, diabetes and anti-cancer effects, is a large class of potential marine drug lead compounds. The main ingredients are toxic proteotoxins, peptides and enzymes. The toxic effects are diverse.

Jellyfish have stinging cells distributed on the surface of tentacles and perioral tissues, and the stinging cells contain a spike sac that stores venom, and the jellyfish emits spikes through the spike sac to inject venom into humans or animals, which has a variety of biological toxic effects on cardiovascular, blood, nerves, muscles, etc. Affected by factors such as climate warming, marine eutrophication and overfishing, the number of jellyfish stings in China's coastal waters has increased explosively. In 1949, Kristenson first reported the symptoms of jellyfish stinging patients.

In the following decades, no breakthrough has been made in the research on the pathophysiology of jellyfish stings, protection and treatment measures, especially the purification and identification of toxin components. Jellyfish toxins are very toxic, as in C

Fleckeri toxin, the lethal dose to humans is only a few tens of micrograms, so it is considered one of the most poisonous poisonous organisms in the world. Jellyfish toxins have strong and extensive biological activities, which can become a unique direction for the research and development of marine biotoxins. [1]

Jellyfish toxin has lethal activity, hemolytic activity, cardiovascular toxicity, liver toxicity, neurotoxicity, enzyme activity, etc., human beings are stung after rash, redness, swelling, itching, pain, blood pressure reduction, and even dyspnea, fainting, shock and death. Some key scientific questions about jellyfish toxins have not yet been clarified, such as the types of toxin proteins, the activity of toxins, purification techniques, and the mechanism of action.

Jellyfish can sting people to death.

Jellyfish English: Auralia is a lower marine invertebrate zooplankton, carnivore, taxonomically belonging to the class Coelenterate phylum Bowl Jellyfish, known about 200 species. Or refers to the species of cubozoa, which was previously thought to be an order of the class Bowl Jellyfish.

The term jellyfish also broadly refers to cnidarians with a jellyfish-shaped bell or saucer, such as hydroids, tube jellyfish, and ctenophores and sea bottles that do not belong to the class Bowl Jellyfish.

Jellyfish in this class are divided into two types: free-swimming jellyfish and sedentary species that attach themselves to seagrass and other objects. The species that resemble hydroids that live in sedentary life constitute the order Crucifera.

Different jellyfish have different morphologies, and there are about 250 species in the world. More than 95% of the jellyfish's body is made up of water, and the rest is made up of proteins and lipids, so the body of the jellyfish is transparent, because of the water in the body, they have no heart, blood, gills and bones. The umbels of the common jellyfish are not very large, only 20-30 cm long.

Some jellyfish are not only changeable in color, but also glow in the water, some shimmer with a faint pale green or blue-purple light, and some have a rainbow-like halo that turns into a brilliant ball of color when they swim in the sea.

5.Jellyfish emits light thanks to a wonderful protein called Equimin, which emits a strong blue light when mixed with calcium ions. The more equimin is in the jellyfish, the stronger the light emitted, and each jellyfish contains only an average of 50 micrograms.

The "most toxic" jellyfish in the world has a high mortality rate after being stung, which makes people's scalp tingle!

Yes, many jellyfish are highly poisonous, such as the monk's hat jellyfish.

Yes Some jellyfish are very poisonous.
