Of course, if you live within easy walking distance of  a more or less natural area where pit vipers are known to occur, you won't want to approach any unknown living snake to see if its pupils are convex and if it bears heat-sensitive pits. To identify venomous snakes from beyond striking distance you must study pictures of the poisonous species in your area and commit the details of their appearances to memory. There is no short-cut.
