Many specimens found in Louisiana are much shorter than this however. Regardless of their total length, eastern coral snakes are easy to distinguish from almost all other snakes in our state by the distinct pattern of alternating black, yellow and red rings across the body. The yellow and red bands are always in contact with each other and the tip of the snout is always black. The only other species that can possibly be mistaken for an eastern coral snake are the milk snake, scar- let snake and scarlet king snake. In all these other species, the alternat- ing red and black bands make contact with each other.
