Other common names

Cornsnake, Corn Snake, Chicken snake, Red ratsnake, Eastern Cornsnake

Basic description

Most adult cornsnakes are about 30-48 inches (76-122 cm) in total length. Adults are orangish-brown with black bordered orange, red, or brownish blotches. There is a spear-shaped pattern on the head and neck. Juveniles are similar in appearance to adults, but they may be more brownish in coloration.

Range in Florida

Cornsnakes are found throughout mainland Florida in every county. They also occur throughout the Florida Keys.

Assessment of risk to people and pets

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