How to Identify the Black Kingsnake (Identification Guide)
The Black Kingsnake is identified by its almost entirely solid, glossy black to very dark brown body, with juveniles sometimes retaining faint traces of a blotched pattern that fades with age.

Key identifying features
The Black Kingsnake is best identified by its nearly uniform, glossy black to very dark brown coloration as an adult, lacking the bold banding or blotching seen in many other kingsnakes. Faint remnants of a lighter pattern, such as subtle flecking or dim crossband outlines, may be visible on close inspection, especially on the lower sides, but from a distance the snake appears almost entirely solid black.
Coloration & pattern
Adults are typically a deep, glossy black or blackish-brown with little to no visible pattern under normal viewing conditions. Juveniles often show a more visible pattern of dim, brownish blotches or crossbands that gradually darken and fade as the snake matures, so young individuals may show more contrast than adults. The belly is usually dark as well, sometimes with faint light mottling near the edges.
Head, eyes & scales
The head is small, rounded, and not triangular, blending smoothly into the neck. Scales are smooth and highly glossy, enhancing the sheen of the solid black coloration. Pupils are round, and there is no heat-sensing facial pit, distinguishing it from venomous pit vipers.
Size & body shape
Adults typically reach 36 to 48 inches, with a moderately thick, muscular body typical of constricting kingsnakes. The tail tapers to a point, and the body maintains an even, cylindrical shape along its length.
Range & habitat where you'll see it
Black Kingsnakes are found in parts of the southeastern and south-central United States, inhabiting woodlands, farmland, and areas near streams and rivers, often taking shelter under logs, rocks, and other surface debris. They are active mostly during the day in cooler months, shifting to more crepuscular or nocturnal activity during peak summer heat.
How to tell it apart from look-alikes
The nearly solid black coloration can cause confusion with black racers or black rat snakes, but the Black Kingsnake has smooth, glossy scales and a stockier build, while racers have a more slender build and rat snakes typically show weakly keeled scales and a more angular head. Faint juvenile patterning that fades with age is also a useful clue when comparing young individuals to other all-dark species. Round pupils and the absence of a facial pit separate it from any venomous species in its range.
