Banded water snake
N. fasciata is natively found from Indiana, south to Louisiana, and east to Florida. Adults of the banded water snake measure from 24 to 42 in in total length, with a record size (in the Florida subspecies) of 62.5 in in total length.
It is typically gray, greenish-gray, or brown in color, with dark crossbanding. Many specimens are so dark in color that their patterning is barely discernible. The ventrum (belly) is typically an off-white to white. They have flat heads, and are fairly heavy-bodied. Banded water snakes may also be identified by a dark stripe which extends from the eye to the angle of the jaw. If irritated, they release a foul-smelling musk to deter predators.
