One to steer away from. This is the only viper that stays with water. Also called a Cottonmouth.

I learned something the other day in conversation with a friend who is a biologist and works in these swamps.
If you get bit, hope it’s by a big one. Turns out a full grown Cottonmouth knows how much venom to use. They are careful because it takes a lot for them to create more. A little guy gives you all he has, and it doesn’t take much…

I’ll try to avoid them all.
Thanks again Buddy!
