Northern watersnake

Description:

The Northern water snake can grow up to 135 cm (4.4 ft) long. They can be brown, gray, reddish, or brownish-black. They have dark crossbands on their necks and dark stripes and blotches on the rest of their bodies, often leading to misidentification as cottonmouths or copperheads by novices. They darken as they age. Some will become almost completely black. The belly of this snake also varies in color. It can be white, yellow, or gray. Usually it also has reddish or black crescents.

Habitat:

Next to a creek in a wooded area

Notes:

Not the best photos, I know, but they are all I have, and I wanted to add some snake spottings from Rhode Island.
