The venter (belly) of the eastern ratsnake is black and white, often resembling a checkerboard pattern with interspersed black blotches. Unlike the checkerboard pattern found on the ventral side of the eastern ratsnake, the venter of the northern black racer is a solid dark gray that changes to a light gray under the tail.

As with all our native snakes the eastern ratsnake would rather flee than fight. In an effort to appear more formidable, the eastern ratsnake distort the shape and size of its head when threatened. The average number of ventral scales did not vary significantly among physiographic regions, dark stripe along each side. If harassed, it will produce a foul-smelling musk to deter predators.
