Climate zones

Habits and Lifestyle

Banded water snakes are solitary creatures. They are active both during the day and at night spending their time basking on logs and branches or hunting in shallow water for prey. These snakes hunt by smell and sight using their vomeronasal organ, also called Jacobson's organ. Banded water snakes are quick to flee from danger, but if cornered or captured, they usually will not hesitate to defend themselves and can inflict a painful bite. If irritated, they release a foul-smelling musk to deter predators. During cold winter months, Banded water snakes hibernate, usually under logs, rocks, or in burrows.
