Corn snake (Pantherophis guttatus)

The corn snake, or red rat snake, is a North American species of rat snake that subdues its small prey by constriction. The name "corn snake" is a holdover from the days when southern farmers stored harvested ears of corn in a wood frame or log building called a crib. Rats and mice came to the corn crib to feed on the corn, and corn snakes came to feed on the rodents. The Oxford English Dictionary cites this usage as far back as 1676.
