Adult specimens attain an average size of {{convert|90|to|122|cm|in}} in total length, with some reaching maximum total lengths of {{convert|147|to|183|cm|in}}.[2][3] It is generally similar to L. getula getula, although its can be distinguished by its geography and appearance. It has a black body that is interspersed with widely spaced yellow or cream-colored speckles, larger and more numerous along the sides. The dorsum in some is unpatterned and in others crossbanded.[2] The venter displays a checked black and yellow (or cream) pattern. Ventral scales range from 197 to 222 in both sexes, with subcaudal scales ranging from 45 to 59 in males and 37 to 51 in females.[1][3] Geographic rangeThe black kingsnake is found in the southeastern quarter of the United States, ranging from southern Illinois to Ohio, then down along the foothills of the Appalachian Mountains and the Alabama River watershed to the northern Gulf Coast in south Alabama and along the coast to the Mississippi River in Louisiana.[2][3] HabitatBlack kingsnakes occupy a wide variety of habitats and is one of the most frequently encountered species by humans in some states.
