The sea wasp, also known as the box jellyfish and marine stinger (Chironex fleckeri Southcott) is the type of the jellyfish that it is said to be the most poisonous animal on our planet. Its unbelievably strong venom can kill its prey in a couple of seconds, meaning that fish and shrimps are easily caught by this underwater predator. There is no chance that they may escape the deadly hug of the sea wasp.

Toxins that are „ingredients“ of the sea wasp’s deadly venom can provoke fatal conditions of the skin cells, nervous system, and heart, as well. Not only is it the most dangerous venom, but injecting is the hell of pain by itself. Terrifyingly consuming and exhausting, it provokes an instant shock or heart failure so it is not rare for humans to drown before they succeed to get to the coast. People who survived this extremely uncomfortable attack witness that they have experienced a significant pain that did not last for days, but for weeks! In the luckiest cases, you will survive the sea wasp attack, but you will stay marked by the „scarring tattoo“ in the area where its tentacles touched your skin.

How to recognize a sea wasp?

Sea wasps can be mostly found in the areas of coastal waters of the Indonesian islands and Australia. As the other jellies, they are transparent, but they are mostly in the shades of light blue tones. Approximately 15 tentacles grows from their bells and every of them can be long up to 3 meters, with its five thousand cells that are supposed to sting the victim. They are not activated when the sea wasp touches its prey, but when it notices the chemical on the external layer of the prey.

Even though people who are not informed about this tiny octopus may found it pretty cute because of its interesting looks, all of you planning to snorkel in the seas of Indonesia should know that you should not consider the sharks as your biggest enemy lurking from the water. Well, literally, they are, but the tiny animal known as blue-ringed octopus should worry you more than a shark.

The first reason for that is pretty obvious – octopuses are pretty smaller than the sharks, and, therefore, you will have to put more effort in noticing them, so you have to be more careful. If you are wondering why you should be that cautious, then you probably do not know that this little buddy, that grows from 5 to 8 inches only, has enough venom to kill a man without much effort. The thing that complicates everything is the fact that there is no antivenom for the venom of the blue-ringed octopus.
