This suspicious slitherer was photographed in Ipswich, Massachusetts. Do you know what kind of snake this is?
Answer
Northern Water Snake.
This is a northern water snake (Nerodia sipedon), probably an adult as the snake appears mostly black, having lost the crossband pattern of his youth. You can see a bit of orange mottling along his underbelly. This non-venomous snake averages two to four feet, and is covered in keeled scales, meaning each individual scale has a ridge down its middle (another helpful identification tool).
