Rattler, a quick question.

Which snake, either nuro or hemitoxin has the fastest acting venom?

By that I mean, considering you are injected with the same amount of venom and receive no medical treatment, which snake's venom is likely to kill the quickest?

The reason I ask is that I have heard of 'one step' snakes and 'two step' snakes, meaning that you will die after taking one step if bitten by one, or you won't take but two steps if bitten by the other.

I don't believe any snake's venom acts this fast, but it got me to wondering which was quickest.
