Agkistrodon piscivorus
Description
The Cottonmouth is a venomous, semiaquatic, piscivorous snake species native to the southeast US and all of Mississippi. This species is most often found in various wetlands including swamps, marshes, streams, ponds, ephemeral wetlands, and lakes. They primarily consist on fish. Cottonmouths are usually thick-bodied, brown, tan, or olive-colored with dark cross-banding. The head is generally thicker than the neck (Behler & King, 1979). They are often active at night, and may be seen crossing roads near wetlands. The best way to safely avoid conflict with venomous snakes is to learn the few species Mississippi has and leaving them alone. Bites most often occur in the event one attempts to kill a snake.
