How does the biggest jellyfish and how it is dangerous? Source:

jellyfish Nomura and man

If you wear a diving suit and descend into the waters of the Yellow sea, you likely will find a huge jellyfish Nomura (Nemopilema nomurai). The diameter of the body of these creatures is about two meters and weight up to 200 pounds — they weigh almost as adult lions. Most of the time they just sway in the water and capture tiny plankton but, if someone approaches them and starts to tease, to trouble. Long tentacles of jellyfish are covered with cells that produce a powerful venom, which scientists still unknown. As produced by the tentacles of a substance poorly known antidote to the jellyfish does not exist yet.

Each year from the venom of the jellyfish Nomura hundreds of thousands of people in China, Korea and Japan. Especially many of the victims of these creatures, there were in autumn 2002-2004. Then the numbers of Nomura jellyfish off the coast of Japan increased sharply, causing swimmers began to bump into them more often. The occurrence of large concentrations of jellyfish in the same region was due to the fact that on the coasts of China and Korea were construction works — huge creatures had to sail away. In addition, the water on the coast of Japan was warm, and the temperature rise from 13 to 23 degrees Celsius provoked a proliferation of jellyfish.

Nomura is one of the largest jellyfish, because its diameter is two meters.

If you get closer to the huge creatures, they're immediately attacked. As soon as the tentacles of the huge establishment touched to the skin people experience severe pain. Subsequently, at the point of contact arise redness and swelling. In some cases it comes to the fact that victims of jellyfish are in a state of shock and even die. But what kind of substances contained in the tentacles of the animal, causing the human body to maximum damage, researchers are still not clear.

Deadly venom

Attempts to identify the exact composition of the venom of the Nomura jellyfish were made before, but seriously engaged in this business only recently. According to research , cells of jellyfish tentacles produce a mixture of more than 200 poisonous substances, but which ones are the most dangerous, no one knew. The researchers were able to "milk" mixture, but splitting it into its component parts proved too difficult.

But, in the end, scientists found a way to extract toxic particles and arrange them in groups. Although it is not very humane, but the researchers cut off a few tentacles of a living jellyfish and placed in the centrifuge. Twirling them around at very high speed, the researchers surpassed all poisonous cells of jellyfish on the surface of their body. Their so-called nematocysts, they learned toxic substances and sorted them by groups. Each substance was tested on the bodies of laboratory mice.

It turned Out that the tentacles of jellyfish Nomura contains at least 13 life-threatening poisons. But the strongest NnLF, which destroys the cells of the organisms and lead to the sticking of blood cells. Organisms laboratory mice literally clogged with thick substances which, ultimately, led to death. Thus, the strongest poison huge jellyfish was finally revealed.

most of the laboratory mice died due to exposure to substances called NnLF

However, the researchers believe that the death of people and animals leads not only the poison, but many other chemical compounds. Rather, they work in different ways affecting completely different groups of bodies. This fact significantly complicates the development of antidotes to the bites of huge creatures, but scientific work in this direction will certainly be continued in the future time.

On the subject of dangerous poisons also recommend reading the article about mancinella tree, which is also known as the "beach Apple". It is included in the "Guinness Book of world records" as the most poisonous tree in the world — if its SAP gets on human skin, it there are large bubbles. Of course, the ingestion of this juice is equal to imminent death. If you want to know about it more .
