The southern black racer is one of the more common subspecies of the nonvenomous Coluber constrictor snake species of the Southeastern United States. The subspecific name priapus refers to the proximal spines of the hemipenes being much enlarged into basal hooks, which is characteristic of this subspecies. These snakes are quite active during the day, which increases the chance of sightings. They eat almost any animal they can overpower, including rodents, frogs, toads, and lizards. Members of this species generally do not tolerate handling – even after months in captivity – and typically strike and flail wildly every time they are handled, often defecating a foul-smelling musk, a common defense against predators in snakes. Adults of the species are usually thin with a jet-black dorsal side with a grey belly and white chin. They are quite fast, giving them the name "racer".
