Pituophis melanoleucus is a harmless colubrid species found in the United States. Adults are large, growing to 48-100 inches (122-254 cm) in length, and are powerfully built. The head is small and somewhat pointed with an enlarged rostral scale that extends upward between the internasal scales. There are usually 4 prefrontal scales. At midbody there are 27-37 rows of keeled dorsal scales. The anal plate is single. The color pattern consists of a light ground color overlaid with black, brown or reddish-brown blotches. When disturbed, it will often hiss loudly, sometimes flattening its head, vibrate its tail and eventually strike at an intruder. Some species will use 'Cloacal Popping' as a defense mechanism. To make the sound, the snakes contract their cloacal sphincter, forcing air (and any other material that happens to be there) out. It is an extremely foul smell that sometimes scares away predators.
