The eastern indigo snake (Drymarchon couperi) is the longest snake native to the United States and is only found in Florida and southern areas of Georgia, Alabama, and Mississippi. Its size ranges between 60 and 84 inches and is not poisonous.
The snake is entirely shiny bluish-black in color with the chin and sides of the head colored reddish or orange-brown. Juvenile eastern indigo snakes have much more red on their heads. Male eastern indigo snakes grow larger in length than females.
The largest non-native snake in the United States is the green anaconda. These snakes reach 20 to 30 feet in length and live about 10 years in the wild. The constrictor native is to South America and is not poisonous.
