Basic description

Most adult North American racers are about 20-56 inches (50-142 cm) in total length. This is a long and slender snake with large and prominent eyes. Adults are black or bluish/black with white or whitish markings on the chin and throat. Juveniles are gray with distinct reddish-brown blotches running down the back of the head and body.

Range in Florida

North American racers are found throughout mainland Florida in every county. They also occur on the Florida Keys.

Assessment of risk to people and pets

Non-Venomous. North American racers are not dangerous to people or pets, but they will readily bite to defend themselves. Racers are not aggressive and avoid direct contact with people and pets. Virtually all bites occur when the snakes are intentionally molested.
