Habitat and Habits: These snakes inhabit the shorelines of lakes, ponds, or streams. They swim well, seeking food (frogs and fish) and safety in the water, and often bask on objects hanging over the water. Water snakes are not venomous, but will bite if cornered or handled. They are sometimes mistakenly called "water moccasins" (which are not native to Michigan).

Reproduction: Females give birth to their 7 to 9 inch young in late summer. There are 8 to 48 babies in a litter. The young are gray or brown with bold black bands.

Range and Status: Northern water snakes are found throughout the Lower Peninsula and the eastern Upper Peninsula. Needless persecution by humans has eliminated water snakes from many places where they were once common.
