Okay, I know that none of you recommend the blue ring, quite the opposite, infact, but I was wondering, if I ever did want one, should I go to my local hospital and get the TTX antivenom? Just in case?? :goofysca:

from The Cephalopod Page: (on page two though)

TTX is a potent neurotoxin that blocks the movement of sodium (Na+) ions across neural membranes by attaching to a Na+ channel receptor and capping the Na+ channel. TTX is particularly effective blocking the propagation of nervous impulses in mammalian myelinated peripheral nerves which produces flaccid voluntary muscle paralysis. This interferes with the muscles of the diaphragm and chest wall and leads to respiratory failure. There is little or no direct effect of TTX on the heart or brain (because it does not cross the blood-brain barrier) until a lack of oxygen causes these organs to fail. One milligram of TTX can kill a person, making it one of the most potent natural toxins known. There is no antidote to TTX. Treatment consists of life-supportive measures including artificial ventilation. This is why researchers in my laboratory studying blue-ringed octopus are required to work in pairs and must be trained in CPR. Patients who survive 24 hours typically make a full recovery, unless lack of oxygen to the brain has caused permanent damage. Interestingly, blue-ringed octopuses are not affected by TTX, probably because they have evolved a slightly different sodium channel receptor that does not interact with the TTX molecule.
