Heart conduction is impaired resulting in arrhythmias, extrasystoles, ventricular fibrillation and other changes which lead to asystole and cardiac arrest. Scientists have long theorized that batrachotoxin-laden animals have evolved mutant. There are 8 million chemical compounds on Earth, yet even the most sophisticated coroner's lab tests for no more than a few hundred of them. They get it from their food supply. Limited to coveralls or other work clothes, boots, and gloves. Origin This extremely toxic plant poison was famously used to kill the Bulgarian dissident Georgi Markov, exiled in London. Nerve agents were made by both sides during the Cold War, but VX became particularly well-known after featuring in Hollywood blockbuster film The Rock.

Previous research conducted by a Harvard team suggested there were multiple origins for the frogs' resistance to their own toxin, but the SUNY team's research suggests that, like the puffer fish, the frogs' resistance comes mainly from a single genetic mutation. The toxin is not just any old toxin, it is batrachotoxin, which previously has been found only in the skin of some South American poison dart frogs.Thats the stuff applied to the tips of arrows to render them more deadly. It is certainly in a human or predator's best interest to spit out the frog immediately, as there is no effective treatment or antidote to the poisoning.
