I am originally from non venomous part of the country Minnesota (years ago) and still cant identify all snakes. i have copper head identification down and had to put down a few in yard as well. this pic is from a friend,(Oklahoma) that shows round versus diamond eyes- but with triangle/diamond head. this snake no doubt had round eyes, but triangle head. personally, based on internet and facts maybe not poisonous due to round eyes? but I wouldn't trust it lol. anyone know what it is?
. I would have though cotton mouth but not if it isn't poisonous.
