The eastern ribbon snake or common ribbon snake (''Thamnophis sauritus sauritus'') is a subspecies of ribbon snake found in the northeastern United States. Some similar species are the western ribbon snake, common garter snake, Plains garter snake, and Butler's garter snake.〔(Mayer 2003)〕 The other subspecies are the northern (''T. s. septentrionalis''), Peninsula (''T. s. sackenii''), and bluestripe (''T. s. nitae'') ribbon snakes. ==Description== The eastern ribbon snake gets its name from its very thin body. At maturity, it grows to between 18 and 86 cm in length.〔(Kingsbury 2007)〕 It is a slender, black snake with a yellow mid-back stripe and one on each side. A brown stripe of one or two rows of scales extends onto the sides of the belly. The rest of the belly is a greenish-white color. It also has two rows of black spots between the back and side stripes. It also has a long tail that is about a third of the length of its body. The labial scales around the mouth of the snake are unmarked and uniformly bright yellow or white. A white or light-yellow bar borders the front of the eyes.〔(Kingsbury 2007)〕 Juveniles are colored like adults.〔(Biological Sciences Towson University )〕 Some aspects of the eastern ribbon snake make it different from a close relative, the garter snake. The eastern has a much thinner body than a garter snake. Its tail makes up about one third of its body length. This snake has stripes on the third and fourth scale rows. The eastern ribbon snake has pure white lips and a mark of white color in front of its eyes. This snake is not venomous.
