You’ll encounter the red-bellied water snake as a non-venomous, semi-aquatic species that’s perfectly harmless to humans despite its aggressive defensive display when threatened.
These fascinating reptiles inhabit wetlands across the southeastern United States, from Virginia to Texas, where they’ve mastered the art of ambush hunting along shorelines.
With their distinctive keeled scales creating a rough texture and that telltale bright orange belly, they’re easier to identify than you’d think.
Adults typically stretch 30-48 inches and feed primarily on frogs, toads, and fish, making them nature’s own pest control specialists.
Their territorial nature means they’ll return to the same basking spots repeatedly, and while they might put on quite the defensive show with coiling and musky secretions, remember that their bite is worse than their bark—which isn’t saying much since they can’t actually bark.
