NON-VENOMOUS
Southern Water Snakes
Nerodia fasciata
Southern Water Snakes are found in the southern states from North Carolina to Texas.
Adults are typically 2 to 3 feet in length. Southern Water Snakes typically have a darker stripe
from the eye angling slightly downward to the end of the jaw. These snakes often darken with age and
obscure the band marking on the back and sides.
There are three subspecies: Nerodia fasciata fasciata, Nerodia fasciata pictiventris,
and Nerodia fasciata confluens.
Nerodia fasciata fasciata is commonly called the Banded Water Snake. The Banded is the subspecies that
occurs in South Carolina. Bandeds are found in the coastal plain regions from North Carolina to Mississippi, excepting
pennisular Flordia. This species sometimes hybridizes with the Northern Water Snakes
in areas where their ranges meet.
Nerodia fasciata confluens is called the Broad-banded Water Snake and is found in coastal Mississippi, all of
Louisianna, eastern Texas, southern and eastern Arkansas, extreme southeast Oklahoma, and portions of Mississippi,
Tennessee, and Missouri close to the Mississippi River.
In areas where the ranges of Bandeds and Broad-bandeds meet, there is intergrade of these subspecies.
Nerodia fasciata pictiventris is called the Florida Water Snake and is found in pennisular Florida.
Also, an isolated population is reported in the southeastern tip of Texas.
