You don’t need fakebook to identify snakes.Yes sir, I will study up. I don’t have FB but my wife does so I’ll ask her to check out that page for me
There are dozens of different internet resources available that don’t require giving up your life history and privacy to access that information.
Here is a start if you want to get close enough to them.
Poisonous snakes with the one exception of a coral snake in Oklahoma have eye pupils that are elliptical running up and down. The rest have round pupils and are non venomous. Actually a great addition to folks living in the country. The non venomous eat rodents and in the case of black snakes, eat rattlesnakes and copperheads as part of their diet.
