I am planning on caching in Northeastern NC (Outer Banks) and Southeastern VA in a couple weeks and have been researching the wildlife in those swampy areas. Even though I've done a lot of research, I'm confused on the differences between the cottonmouth, water moccasin, and the black water snake. Is the cottonmouth and water moccasin the same snake? Are black water snakes poisonous?
Thanks,
Jim
The snakes listed by WARedBear are the only poisonous snakes in North America and the water moccasin and cottonmouth are two different names for the same snake. The moccasin, copperhead and rattler are all pit vipers and are readily recognized by their heart shaped heads. The coral snake on the other hand resembles a king snake with its alternating bands of red, yellow and black.
