What is a nerodia erythrogaster?

Nerodia erythrogaster, commonly known as the plain-bellied water snake, is a non-venomous snake found primarily in the southeastern United States. It typically inhabits aquatic environments such as rivers, ponds, and marshes. Characterized by its olive-brown or grayish body and distinctive pale yellow or cream-colored belly, it primarily feeds on fish and amphibians. While generally docile, it can be defensive if threatened, often mimicking venomous species.
