About this species

Virginia's most commonly encountered water snake, the northern watersnake is a heavy-bodied, non-venomous snake found near virtually any body of fresh water statewide. It is frequently and dangerously misidentified as a cottonmouth — which is only found in southeastern Virginia. Watersnakes are defensive and will bite if handled, but are not venomous.

Did you know

"When threatened, northern watersnakes flatten their bodies and release a foul-smelling musk — an effective deterrent that unfortunately makes them unpleasant to handle even for experienced herpetologists."
