That pic I posted is a water moccasin, also known as a cottonmouth.
(Which I surprisingly just learned are one in the same...I always thought a cottonmouth was a version of rattlesnake.)
Here's one getting handled...although I don't know what in the world this guy was thinking picking it up like that after he shot it.
