2. Blue-ringed octopus
This octopus is tiny but as you might have guessed really deadly. it kills its victims in a very cruel way it bites the victim and injects poison into the bloodstream after that the victim gets paralyzed within a few minutes which of course means they can’t breathe. the only way to help a person, in this case, is to start artificial respiration and continue to do it for the next few hours until the effect of the poison wears down number.
