Looking for a vacation and want to soak up the warm sea? However, danger can await you, and these are jellyfish, which at first glance seem completely harmless. In some cases, touching a poisonous jellyfish can even be fatal.
We will tell you about which jellyfish in the sea it is better not to approach or touch them in order to avoid serious consequences for their health. Jellyfish creatures are amazing and many of them can reach simply gigantic sizes. Sometimes real monsters come across with tentacles up to forty meters long and a dome diameter of up to two and a half meters. There are bright representatives of jellyfish, a meeting with which certainly will not bring anything good.
For example, the poison of a jellyfish sea wasp can be fatal to 60 people. Even after the death, the stinging tentacles of the jellyfish continue to sting. These creatures can accumulate in one place, forming swarms or the so-called flowering on the water. Mostly jellyfish live in salty sea water, but there are some species that can be found in freshwater reservoirs. In rainy times, the number of jellyfish decreases, but in the summer there are especially many.
Sea nettle
Jellyfish is common along the coast of North America. In summertime, in the ocean you can see whole clusters of jellyfish, which are combined into huge layers. The largest specimens can reach sizes up to thirty centimeters in diameter.At the tips of the tentacles are stinging cells, which, when touched, leave a very unpleasant and painful rash on the skin.
Hairy cyanoea
Hairy cyanosis is considered a real giant among jellyfish. Adult individuals can grow up to two and a half meters, and tentacles sometimes stretch for thirty meters. Meeting with fibrous cyanosis is an unpleasant phenomenon. This species of jellyfish inhabits the entire North Atlantic. You can meet her even in the waters near the UK. The jellyfish bite is incredibly painful and her sting remains active, even after her death. In case of untimely provision of medical care, a person's life is in danger.
Portuguese boat
Portuguese boat looks very unusual. It has a blue color and in Australia the locals call it the “blue bottle”. This dangerous jellyfish is found in almost all oceans of the world. The bite of this jellyfish is painful. A person feels severe pain, burning, skin swells and becomes hot. In some cases, a collision with a jellyfish can be fatal in nature, as shock, fever sometimes develops, the respiratory and cardiovascular systems of the body are disrupted.
Jellyfish irukanji
A small but very poisonous jellyfish irrukanji is found in many oceans, and can even be found in the northern waters of the British Isles. The diameter of the jellyfish does not exceed five millimeters, but the modest size is offset by incredibly toxic poison. The poison of this jellyfish is a hundred times stronger than the poison of a cobra. In some cases, a lethal syndrome does not develop, but a person is faced with severe muscle pain, cramps, burning of the skin, heart palpitations and headaches.
Sea wasp
One of the most dangerous and deadly jellyfish that lives off the coast of Australia and Southeast Asia. This outwardly not terrible, but dangerous creature, which only in Australia since 1954 has brought more than 5568 deaths. Stinging tentacles of jellyfish can reach a length of three meters and each of them is covered with millions of stinging cells that can sting at any time. One jellyfish contains as much toxic poison as is enough to kill sixty people. In this case, the poison acts in such a way that it affects the central nervous system of the body, which causes severe suffocation and paralysis. Therefore, it is better not to meet with this jellyfish in the open sea.
Jellyfish lion's mane
This jellyfish looks pretty impressive. Its tentacles, covered with millions of stinging cells, can reach thirty meters in length. Outwardly, it looks very beautiful and is not in vain reminiscent of a lion’s mane, especially with its bright orange color. The diameter of the dome can reach two and a half meters.
Touching a jellyfish leaves a very painful and long healing burn, and the toxins in the poison cause a severe allergic reaction from the body. This unusual specimen is found in the territory of the Pacific and Atlantic Ocean.
Medusa Nomura
Medusa Nomura is a giant whose diameter can reach two meters. Some individuals in natural conditions grow up to two hundred kilograms. With such a monster just do not want to meet on the high seas alone.
Quite often, large jellyfish are found in the Japanese and East China Sea. Local fishermen complain that getting into the jellyfish catch forces him to throw it out completely, since its poison is incredibly toxic and it can kill a person.
