Meet the blue-ringed octopus, the cutest killer on the seabed

The seabed is definitely one of the most complex regions to be explored by man. As amazing as the universe of space travel itself, the pursuit of knowledge in sub-ocean territory can be as incredible as the discovery of life on other planets.

A great example of the complexity of marine life is one of the most beautiful and poisonous creatures in the world. It is called the blue-ringed octopus (scientific name Hapalochlaena spotted ). The creature is usually found between Japan and Oceania, that is, in the seas of the Pacific Ocean, and fortunately only attacks those who have the courage to provoke it.

When some unfortunate being without love for life does this, the octopus's body responds to the stimulus by extolling the blue rings - which function more or less as an indicator of certain death. As a result, the aggressiveness of the cephalopod reaches very high levels and it attacks its prey by jumping over it. Through bites with its small mouth, the octopus injects its lethal poison, which is capable of killing a creature up to 1.2 ton (1, 200 kilograms).

Interestingly, this species of octopus is very small and at most the size of a golf ball. Even so, the toxic substance it possesses can kill a person within 30 minutes. Luckily, the rate of incidents with this dangerous animal is very low - which is great, as there are no antidotes that can counteract the ferocity of blue-ringed octopus poison.

Also, if a person has been attacked by the animal, it must be kept under intensive medical care, and breathing must be done artificially. This condition should be maintained until the body itself can excrete the poison in the urine.

In time, just out of curiosity, it is worth remembering that the most dangerous animal in terms of poison lethality is also on the Australian coast. It is a species of jellyfish called the sea wasp (scientific name Chinorex fleckeri ). According to USP researcher José Carlos de Freitas, this fatal creature contains enough poison to kill up to 60 adult people.

So if you're out in the open in the Australian Sea, it's best to keep an eye out for very beautiful or long-legged creatures. They can be fatal!
