There are a number of species of snakes that, while not inviting, are not venomous. The rattlesnake is most definitely not one of them. If you hear the classic sound of this viper's rattling tail, you know to get as far away as possible before becoming its next meal. The adult rattler always gives this little shake of the tail before striking. Maybe this is some sort of forewarning or maybe it just has such confidence that it can get you, that it will tell you it's coming. (Can you tell I'm not a fan of snakes?)
