Southern black racer (juvenile)

Coluber constrictor priapus, commonly known as the southern black racer, is one of the more common subspecies of nonvenomous Coluber constrictor snakes in the Southeastern United States. The 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 will eat almost any animal they can overpower, including, rodents, frogs, toads, and lizards. They have been known to charge at people in an attempt to frighten them, but will usually retreat – if challenged. Members of this species generally do not tolerate handling – even after months in captivity – and will typically strike and flail wildly every time they are handled. These snakes 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". (information from Wikipedia)
