The most dangerous jellyfish in the world
As if we don’t need more evidence that the ocean is trying to get back at us for our behaviour, we now present the most poisonous jellyfish in the world. Seemingly lifeless and without any will, the sting and possible death the jellyfish are responsible for happens more in the style of walking blindly into traffic than actually being ambushed by one of the deadliest killers in the world. It’s no surprise to anyone who has encountered one of these jellyfish why an alien as you know it from films looks more like a jellyfish than a shark does. By the unimpressive abilities they possess, their incredible beauty and the devastation they can cause.
The yellow jellyfish (Lion's Mane Jellyfish)
At the beginning we will introduce you to what looks more like a drawing by Salvadore Dali, also known as the yellow jellyfish. With an umbrella up to one meter in diameter and tentacles up to 30 meters long, they live in the colder waters of the northern Atlantic and Australia. They travel in small flocks and have a bio-fluorescent shimmer, they are like a kind of underwater stars that do not lose their incredibly painful sting long after their death.
Compass Jellyfish (Sea Nettle jellyfish)
Next we have the compass jellyfish, a very common jellyfish species that lives in shoals, typically in the eastern USA. If you find yourself in the middle of one of these swarms, it will be more like kicking an African bee swarm – total confusion and a lot of pain. With a length of 2 meters, the sting of a compass jellyfish can cause long and painful rashes, but is rarely fatal.
Stomolophus meleagris (Cannonball jellyfish)
With a name like 18th-century artillery, you can be sure it will strike hard. Stomolophus meleagris, called jellyfish in Cannonball is the third on our list. It is more of a mutated fungus from Alice in Wonderland, yet its sting is very painful but rarely fatal. The good thing is, if you want to take revenge on the jellyfish that stung you, you can just dry it and eat it as a delicacy.
The Portuguese Galley
The Portuguese galley in the English “Man-O-War” has a name like a wrestler and behaves just as pompously. Less a jellyfish, but rather many organisms that work together in a symbiotic way to survive in the waters of Australia and Northern Scotland. In Australia they are also called “the Blue bottle” and are one of the main causes of pain in Australia. There are over 10,000 incidents a year in Australia alone, the pain of her sting lasts for several days and can sometimes lead to death.
The Irukandji jellyfish, the deadly insect in the world of jellyfish measures only 2 cm and is known as one of the most poisonous jellyfish in the world. The horrible agony of being bitten by this jellyfish begins with a small sting similar to that of a mosquito. Possibly this is the beginning of the so-called “Irukandji Syndrome” with pain and the feeling of imminent doom, there have been many victims who have asked their doctor to kill them to end the pain. The symptoms include everything the human body knows as pain, such as severe headaches, back pain, muscle aches, chest and abdominal pain, nausea and vomiting, sweating attacks, high blood pressure, palpitations and pulmonary oedema. Many of the symptoms, however, start to disappear again after 2 weeks.
The Dice Jellyfish (Box Jellyfish)
First place is taken by the notorious dice jellyfish, it is no surprise that it is found in Australia and South East Asia. Don’t let the harmless name fool you, with 24 eyes, 4 brains, and 60 anal regions it’s really an alien that lives among us. Since 1954 it has been responsible for 5568 deaths. It has 15 tentacles, each with 500,000 poisonous spines on it. The sting is so painful that many victims drown due to the shock they have after the sting. If you are one of the lucky ones who survived this sting, after 2 weeks of paralyzing pain you will have bad scars that will remind you for the rest of your life to do more things on land.
