What Is The Deadliest Octopus?

In an academic study from 2009, it was discovered that all species of octopus, cuttlefish, and even some squid are actually venomous, although not all octopus venom is lethal to humans and has very little effect on most land-dwelling animals. 

However, there is one species of octopus that is capable of killing a human being in minutes.

The Venomous Blue-Ringed Octopus

The deadliest Octopus on the world is called the Blue-Ringed Octopus, and can only be found among the warm and shallow waters of the Australian coast. 

The reason this particular species is so deadly is because their venom contains a paralyzing neurotoxin called tetrodotoxin, which the octopus can secrete from all areas of its body.

Known for their vibrant colors and deadly venom, Blue-Ringed Octopuses are actually one of the smallest species of octopus in the entire world and will usually only grow to around 2.5 inches in length. 

What to Do if Bitten by a Blue-Ringed Octopus

If you are ever unfortunate enough to be bitten by a Blue-Ringed Octopus, then you have to seek immediate medical attention, although there is actually no guarantee that the venom will immediately kill you. 

Although the octopus’s venom is considered one of the most deadly substances in the world, there have been people who have survived encounters with the tentacled creature.

And to date, there have only been three recorded deaths attributed to the Blue-Ringed Octopus and its venom. 

So if you are planning on going to Australia, always make sure to keep an eye out for these tiny terrors when you are in the water! 

Final Thoughts

While most species of octopus are not deadly to humans, it’s still important to remember that these are wild creatures. If you encounter any of these creatures in the wild, remember to respect their space.
