Scientists have continued to look into whether octopuses are poisonous. Modern research indicates that all types of octopuses contain traces of venom proteins in their bodies, although there is some difference of opinion on which octopuses are actually dangerous for humans. There is general agreement that the venom produced by the blue-ringed octopus is definitely poisonous to humans. Research into other types of octupuses has continued.
More facts about octopuses and venom:
- The blue-ringed octopus, commonly found in the western part of the Pacific Ocean and along the coast of Australia, carries enough poison to kill 26 adult humans in a matter of minutes.
- The name for the blue-ringed octopus comes from the series of blue rings on its body. When the octopus is at rest, the rings are barely distinguishable. When threatened or in pursuit of prey, the rings become a bright blue, indicating that the creature is about to strike.
- The bite of the blue-ringed octopus is similar to that of a bee sting, involving very little pain. Within minutes, however, the venom injected during the bite begins to paralyze the victim's nervous system. There is no known antidote, so the victim's only hope for survival is to be placed on an artificial respirator until the poison has passed out of his or her body.
