Agkistrodon piscivorus is a venomous snake, a species of pit viper, found in the eastern United States. Adults are large and capable of delivering a painful and potentially fatal bite, but are not normally aggressive. This is the world's only semi-aquatic viper, usually found in or near water, particularly in slow-moving and shallow lakes and streams. The snake is a strong swimmer and will even enter the sea, successfully colonizing islands off both the Atlantic and Gulf coasts. The common names for the species include variants on water moccasin, swamp moccasin or black moccasin; viper, cottonmouth and rattler. Many of the common names refer to the threat display, where this species will often stand its ground and gape at an intruder, exposing the white lining of its mouth.
