This constrictor really isn't. The southern black racer is known in the scientific world as Coluber constrictor, but it doesn't constrict its prey as the name suggests. Instead, it grabs its target, holds it tight with its jaws and presses it into the ground until it stops struggling.

Then it swallows it whole.

The Southern black racer's common name has another contradiction. This snake can be found pretty much everywhere in the eastern half of the United States, from Texas to Minnesota to Maine to Florida. Restricted to the south, it's not.

Southern black racers are found throughout Florida, including the Keys. It's a common snake throughout its range. Habitat includes pinelands, hammocks, scrubs, prairies, sandhils and cypress woods. It's also found in urban settings.

Most adults are between two to five feet long, with six feet being the record for this racer. Adults are uniformly black with white markings on the chin and throat. Its pupils are round. Juveniles, on the other hand, are mostly a blotchy reddish-brown with a solid black tail.

They don't call these snakes racers for nothing. They are fast, and would rather use speed to get away from danger than confront it. And it is skitterish. But if cornered, it will stand and fight, which means using its sharp teeth. It is non-venomous, however.

It's also an excellent climber and swimmer.

Dinner for the southern black racer includes frogs (the snake at left just swallowed a Cuban tree frog), lizards, rodents birds, bird eggs and small snakes. It in turn, it is dinner for hawks, some mammals and larger snakes. Its biggest enemy, however, is human — fear and ignorance coupled with the occasional car accident takes a large toll on the southern black racer.

It is most active during the day, hunting by sight. At night and in cool weather, it will retreat into burrows or take shelter under a log.

Breeding season is March to June; a female will lay a clutch of 6 to 20 eggs that hatch between May and August.

Southern black racers are members of Colubridae, the largest family of snakes on the planet. Other common names include black racer, or simply racer.
