I would like to explain what a “pit viper” is, everyone has different Ideas why they are called that, they are mean when cornered. The are great in snake fights and many others. The real reason they are called pit vipers is because they have thermal pits on their noses, they uses these to find prey in pitch black conditions, like thermal goggles if you will. when you combine this with their amazing sense of smell it makes them just that more dangerous.
