Basic description

Most adult eastern kingsnakes are about 36-48 inches (90-122 cm) in total length. These snakes are solid black to chocolate brown, with several narrow white to yellowish crossbands down the back and a narrow chain-like pattern on the sides. The neck is indistinct and the scales are smooth and shiny. Juveniles resemble adults in color and pattern.

Range in Florida

Eastern kingsnakes are found north of a line from Pinellas County to Flagler County and west into the Panhandle, excluding the eastern Apalachicola lowlands south of Telogia Creek. They are occasionally found on barrier islands in the Gulf of Mexico (e.g., the Cedar Keys). Eastern kingsnakes are also known to interbreed with other kingsnake species throughout large portions of their range.

Assessment of risk to people and pets

Non-venomous. Eastern kingsnakes are not dangerous to people or pets, but they occasionally bite to defend themselves. These snakes avoid direct contact with people and pets. Virtually all bites occur when people intentionally bother the snakes.
