Florida Rat Snake is one of the most common non-venomous snakes in Florida. Known for controlling rodent populations, this snake is fascinating yet often misunderstood. This guide helps you identify the Florida Rat Snake, understand its behavior, recognize species, and coexist safely.

1. Florida Rat Snake Identification

Scientific Name: Pantherophis alleghaniensis (Eastern Rat Snake), Pantherophis obsoletus (Black Rat Snake)
Other Names: Chicken Snake, Black Racer (some regional overlap)

Physical Features:

• Coloration: Varies by species and age. Younger snakes are patterned with blotches, while adults are often solid black, gray, or brown.

• Size: Typically 3–6 feet, with some reaching up to 7 feet.

• Head Shape: Narrow, elongated head; pupils round (non-venomous sign).

• Scales: Smooth, glossy scales that give them a sleek appearance.

How to Differentiate from Other Species:

• Unlike venomous snakes (cottonmouths, copperheads), rat snakes are non-venomous and have round pupils.

• Rat snakes are often confused with racers, but rat snakes move slower and are more likely to climb trees or walls.
