The Blue-Ringed Octopus is very small, only the size of a golf ball, but its venom is so powerful that can kill a human. Actually it carries enough poisonto kill 26 adult humans within minutes, and there is no antidote. They are currently recognized as one of the world’s most venomous animals.
Its painless bite may seem harmless, but the deadly neurotoxins begin working immediately resulting in muscular weakness, numbness, followed by a cessation and breathing and ultimately death.
They can be found in tide pools in the Pacific Ocean, from Japan to Australia.
