Gizmodo:

A tourist in Australia has gone viral after posting a video of themselves holding a blue-ringed octopus. But it hasn’t gone viral just because the animal is beautiful. The blue-ringed octopus is one of the most venomous creatures in Australia and the unnamed tourist is lucky to be alive.

The venom of the blue-ringed octopus, which contains the neurotoxin tetrodotoxin, causes paralysis and the sting is so small that most people have no idea that they’ve been poisoned until it’s too late. It carries enough venom to kill 26 full grown adults in a span of minutes.

I showed this video to my Australian wife when it first made the rounds and she said, “So, how long did it take to kill them?” Don’t mess with the wildlife in Australia.
