Mole King Snake

Basic description

Most adult northern mole kingsnakes are about 30-42 inches (76-107 cm) in total length. Adults are gray, brown, or orangish, with typically around 55 black-bordered reddish-brown blotches down the body and tail. Older individuals may be almost solid brown. The neck is indistinct, and there is sometimes a dark line through the eye. Juveniles are similar in appearance to adults but more vivid and with a silvery ground color.

Range in Florida

Northern mole kingsnakes are found in the Panhandle east to Franklin and Liberty counties.

Assessment of risk to people and pets

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