Northern Water Snakes
Greenwood Furnace State Park
The northern water snake can be seen in a variety of colors. On some adults, the patterns can blend into the background color, making them appear completely black.
Northern water snakes are important to the balance of nature because they eat small fish, frogs, toads, and crayfish and are food for other predators.
Water snakes wrap their tails together when they mate. You might see this twist of snakes in or out of the water.
Don’t confuse a harmless northern water snake with a venomous northern copperhead or eastern cottonmouth. Copperheads have obviously flatted, triangle-shaped heads. Don’t worry about eastern cottonmouths (also known as water moccasins)-they don’t live in Pennsylvania. The northern water snake may also be confused with the non-venomous eastern milk snake.
Venomous vs. Non-Venomous
Copperheads (and all other venomous snakes in Pennsylvania have vertical pupils like a cat’s eye. Our non-venomous snakes have round pupils like we do.

I Spy..Slithering Snakes
You might see snakes:
*Basking in the sun to raise their body temperature in spring and fall. In summer, cold-blooded snakes prefer the shade so they don’t overheat.
*Growing from the length of six to ten inches when they’re born in July and August, to two to three feet as adults.
*Hunting by pursuing their prey in the winter, under rocks and through crevices, then swallowing it head first.
