The southern black racer (Coluber constrictor priapus) is one of the more common subspecies of the non-venomous Coluber constrictor snake species of the Southeastern United States. 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 rise to the name "racer".
