Wishlist: Blue-Ringed Octopus

This slideshow requires JavaScript.

The blue-ringed octopus is one of the most dangerous marine species in the world. Although it is generally docile in nature and only 5-8″ long, its venom is powerful enough to kill humans (and there is no antivenom for it). The neurotoxin it uses, called tetrodotoxin, is 1,200 times more toxic than cyanide. This neurotoxin causes motor paralysis and respiratory arrest within minutes, which leads to cardiac arrest due to a lack of oxygen. The venom can also result in nausea, heart failure, paralysis, and blindness, eventually leading to death within a few minutes. A single blue-ringed octopus carries enough venom to kill 26 adults!

The good thing is it is possible to survive a bite from a blue-ringed octopus. The victim can be saved through artificial respiration, if started soon enough and kept up for the entire time the person is paralyzed until they can start breathing on their own again.

We someday want a wet specimen of this octopus for our collection, because it’s one of the most venomous species in the world (and it looks cool)!
