Corn snakes are slender with a length of 24 to 72 inches (61 to 182 cm). They are usually orange or brownish-yellow, with large, black-edged red blotches down the middle of the back. On the belly are alternating rows of black and white marks, resembling a checkerboard pattern. Considerable variation occurs in the coloration and patterns of individual snakes, depending on the age of the snake and the region of the country in which it is found. Hatchlings lack much of the bright coloration found on adults. Corn snakes are primarily diurnal. They readily climb trees and enter abandoned buildings in search of prey. However, they are very secretive and spend most of their time underground prowling through rodent burrows. They also often hide under loose bark and beneath logs, rocks, and other debris during the day.
