What color is a garter snake?

Answer 1

Gopher Snakes are light colored dorsally (white to beige), with contrasting dark saddles and blotches (brown to black). Gopher Snakes have a light ventral coloration that may have a dark checkered pattern. There is a dark line that extends across the snout and on past each eye. Gopher Snakes have keeled scales, this helps distinguish young Gopher Snakes from juvenile Racers, which have smooth scales. Gopher Snakes have round pupils, which is different from both Night Snakes and Western Rattlesnakes. These two species could be confused for Gopher Snakes, but both have vertical pupils.

Answer 2

Where I live, the eastern garter snake is black with a yellow stripe down its back. Rounded head, round pupils.

Answer 3

Are you referring to the subspecies "Northern Ribbon Snake"? If so, they are either black or brown and have three bright yellow or white stripes their back and sides.
