Plain-bellied Watersnakes, also known as Yellow-bellied Watersnakes, are commonly observed snakes found in large bodies of water throughout the state of Mississippi (excluding extreme northeast). Habitat examples are swamps, lakes, rivers, ponds, and ditches. Labial scales are strongly barred, and the yellowish belly can usually be seen from a view to the side. Belly is plain and unmarked. Scales are strongly keeled, as they are in all Nerodia. Adults may reach lengths of up to 4 feet (Powell et al., 2016). They are harmless. They primarily eat fish.
- Adults with a nearly patternless back, and a plain belly that may be red, orange, or yellow (most commonly yellow in MS)
- Juveniles more boldly patterned with dorsal blotching
