Other

Active day and night. Frequently encountered basking on rocks or stumps, hunting frogs in shoreline vegetation during the day, or gorging itself on minnows and small fishes caught sleeping in the shallows at night. Also eats salamanders, juvenile turtles, crustaceans, even small mammals. Will flee if given the chance, but flattens body and strikes repeatedly if cornered. Wounds caused by the bite bleed profusely because of the anticoagulant quality of the snake's saliva, but there is no poison. Northern Water Snakes are often mistaken for venomous "water moccasins" and killed on sights.
