Mississippi Green Watersnake vs. Common Watersnake

Two heavy watersnakes of the southern tip. The Common Watersnake is banded near the head and blotched down the body at every age; the Mississippi Green Watersnake is plain dark olive-green to brown with only faint marks, even when young. Up close, the Mississippi Green has a row of small scales between the eye and the upper lip, so the eye does not touch the lip; its belly is dark with pale half-moons and its chin and throat yellow.
