Southern Black Racer

The southern black racer is one of the more common subspecies of the eastern racer. The specific name priapus is in reference to the proximal spines of the hemipenes that are enlarged into basal hooks. They are quite active during the day increasing their chances of sightings. True to its name, the species can move very fast.

On confrontation, the shy snake usually flees, relying on its speed. If it cannot do so or is cornered, it inflicts painful bites repeatedly. But it is non-venomous and harmless. The bitten area should be cleaned with warm water and soap to prevent infection.

As pets, they generally do not tolerate handling even after months of captivity. Every time they are handled, they typically strike and swing wildly. This is accompanied by defecating a musk of unpleasant smell.

Southern Black Racers at a Glance


It lives in and around the southern regions of the US. The range is spread widely throughout Florida mainland and the Florida keys. Outside Florida, the range spreads throughout the eastern regions of the US, from northeast Texas.

Coluber constrictor priapus


It inhabits pinelands, forests, grassy areas, open woodlands, hardwood hammocks, brush, sandhills, prairies, scrub, desert, and cypress strands.


It lives for around 10 years.


Natural predators of the serpent are birds of prey like hawks, including the broad-winged and red-shouldered hawks. These birds have keen eyesight and drop down from the sky to capture the snakes in a way that makes the latter’s speed and ground awareness ineffective. But humans are the greatest enemies of the southern black racer. Many are killed on highways and intentionally, out of fear.


It eats almost any animal that it can overpower, including frogs, insects, moles, rodents, lizards, toads, and small snakes. It also consumes birds and their eggs. Despite the constrictor in its scientific name, the snake suffocates or crushes its victim to the ground rather than constricting it.
