In Queensland, Australia, two English tourists and a German have fun with a Hapalochlaena maculosa or 'blue-ringed octopus' - an extremely poisonous species that can kill a person in minutes. The three men just caught the animal they thought was a harmless sort. One of them wanted to make a picture with small octopus on hand. The shooting lasted 30 seconds, and then released the octopus in water, taking care to remove the hook. Only after showing the video to their friends realized they were an octopus with blue rings, the only cephalopod that can kill a man.
