In Texas, you're four times more likely to be killed by lightning than a snakebite. We have an average of two to three deaths per year from snakebites, compared with five to seven for insect bites and eight from lightning.
Snakes range farther north and occur at higher elevations than lizards.
They are also adapted to a much wider range of environmental conditions. There are no snakes in Ireland, Newfoundland, New Zealand or many South Sea islands. Contrary to popular belief, snake skin is not clammy or slimy, but smooth, dry, and slightly cool to the touch. You need to watch where you step down under. Rattlesnakes can't hear the sound of their own rattles.
