Good afternoon, I came across a really cool informative website which focuses in on the just the 7 species of Poisinous snakes found in the State of Louisiana. In doing so, the website, www.PreserveVenemous.com gives you multiple pictures and good information on how lethal the bites are of say the Cottonmouth and the Copperhead.
FYI, part of the reason I post this information is because I cannot stand the ignorant statement "the only good snake is a dead snake". I used to catch speckled kings and blackrunners as a kid. Snakes are just another part of our diverse wildlife and there is a good reason kings snakes are named king snakes!
Hope you enjoy.
