Nerodia fasciata
Description
Nerodia fasciata is a harmless medium-sized watersnake found in along coastal and adjacent counties, and in drainages of the Mississippi River Habitat examples are swamps, lakes, rivers, ponds, and ditches. The Broad-banded Watersnake exists in Mississippi River habitats and near the LA border. Labial scales are strongly barred. Patterning is often quite colorful, consisting of reddish, orange, or brown banding along the dorsum. Juveniles may be much more colorful than adults. Belly usually blotched with red checkering (see image below). Scales are strongly keeled, as they are in all Nerodia. Adults reach lengths of up to 4 feet (Powell et al., 2016). This species is often mistaken for the venomous cottonmouth. This species nonvenomous. If confused, spending some time really learning venomous species will help. They primarily eat fish.
