I cannot stand snakes, I'd never be able to tell which ones are poisonous or not.  Do you know how to tell?
I think that you can tell which are poisonous by the shape of their eyes.
I'm not sure I'd want to get that close to figure it out!!  I've seen way too many tv shows about what snake venom can do.
Yeah, I don't want to get close either. Vomiting, trouble seeing, tingling of limbs and sweating do not sound fun at all.
And it sounds like if you don't get the anti-venom soon enough, you can actually die from some of them!  Do you know which ones can be fatal snake bites?
Rattle snake bites can be fatal and cotton mouth.
Wow - rattle snakes are pretty common around here in Georgia - and I've always been scared of cotton mouths - it's one reason I won't go into lake or river water.
I think there are about 26 known species of rattle snakes in the US.
