Box Jellyfish

What do you think is the deadliest sea creature of all? A shark? Saltwater crocodile? A blue ringed octopus perhaps? If these were your guesses, you guessed wrong.

The correct answer is the creature seemingly more fragile than any animal mentioned beforehand - the infamous box jellyfish, also known as the sea wasp.

With the length that sometimes exceeds 10 feet (3 m), it can kill up to 50 humans with the amount of venom located in a single tentacle. The fact that an average box jellyfish has around 60 tentacles should give you the basic idea of how deadly this creature really is.

If you were stung by a sea wasp while swimming, you basically would have no chance of survival, as thousands of stinging cells would inject the deadliest venom on planet directly into your bloodstream.

Extreme pain, shock, as well as cardiac and respiratory arrest would occur almost immediately. Death would follow within mere 3 minutes.

Box Jellyfish Habitat

Box Jellyfish (chironex fleckeri) mostly inhabits waters off the coast of Australia and Indo-Pacific region. The sea wasp season in Australia typically lasts from October to April each year.

In Hawaii on the other hand, they can be found throughout the year, making them even a bigger threat to humans.

Box Jellyfish Sting Treatment

If you were stung by a box jellyfish, you should by no means use alcohol or methylated spirit. Domestic vinegars have been confirmed as an effective treatment as they disable the sea wasp's nematocysts not yet discharged into the bloodstream.

Pressure immobilisation can also be used on limbs to slow down the spreading of the deadly venom.

Besides the agonising pain, box jellyfish stings also cause severe scars on the parts of skin where the contact was made.
