Blue-Ringed Octopus
This octopus is really little in stature, but it is unquestionably lethal. That is, it captures the victim and then injects poison into the victim’s bloodstream, which is a very painful method of killing. Within a few minutes, the sufferer becomes paralyzed, and as a result, he or she is unable to breathe. The only option to help someone in that situation is to employ artificial respiration for one hour, or until all traces of poison have been eliminated.
