Most are gray, brown, or greenish with three yellowish stripes down the back, and there may be black spots between the stripes, making the snake look "checkered". The belly is pale white, green, or yellow. The tongue is red with a black tip. Adult Length: 2 to 4 feet. Habitat and Habits Common Garter Snakes are found almost everywhere—in fields, marshes, woods, parks, and backyards. They feed on earthworms, frogs, toads, tadpoles, fish, and small mammals. Like many snakes, they release a foul musky odor when threatened or handled. Reproduction From 6 to 50 young are born alive in mid to late summer. Range and Status This species is the most common snake throughout Michigan.
