Mississippi is home to six venomous snake species, including rattlesnakes, cottonmouths, and copperheads, according to wildlife officials. Experts recommend learning to recognize the full range of a snake’s features rather than relying on single clues for identification.
Venomous snakes such as rattlesnakes, cottonmouths, and copperheads have heat-sensing facial pits, classifying them as pit vipers. These snakes typically have slit-like pupils, whereas nonvenomous native snakes usually have round pupils. However, low light conditions can cause pupils to appear round, and some species may have dark irises that obscure pupil shape.
Another characteristic is scale arrangement beneath the tail. Pit vipers have a single row of scales after the vent (cloaca), while nonvenomous snakes have a double row. Officials caution that examining these features can be difficult and should never involve handling snakes in the field.
Additionally, three of Mississippi’s six venomous snakes are rattlesnakes, which usually have a rattle on the tail. Pygmy rattlesnakes, however, may have a small or no rattle at all. Experts advise outdoor enthusiasts to watch where they step and place their hands, especially around stump holes, under boards, in brush piles, or near fallen logs, where snakes often seek shelter.
