Ohio has only three species of venomous snakes. Two rattlers and then the copperhead, which is a close relative of the cottonmouth, which is NOT found in Ohio. When inbred people see a snake in the water, it is always a cottonmouth, just because they like to keep it in the family and avoid actually reading any sort of literature on the subject. Non-venomous watersnakes have a saliva that contains an anti-coagulant that prevents the blood from clotting, so you may bleed a bit if you get bit. They also like to throw up their last meal when captured, which I have seen firsthand. I have also seen footage of watersnakes actually coming up to a person and taking fish from their hands. Cottonmouths tend to be very laid-back snakes for the most part and don't thrash about and strike often when caught. Youtube has plenty of footage of those magnificent animals and most of the time they do the usual gaping, which is how they got their name. The Bible is bullshit as well:)
