The corn snake (Elaphe guttata), or red rat snake, is a North American species of rat snake that subdue their small prey with constriction. The name “corn snake” comes from the fact that they have a maize-like pattern on their bellies and because they were found in corn fields. The Oxford English Dictionary cites this usage as far back as 1676. Corn snakes are found throughout the southeastern and central United States. Their docile nature, reluctance to bite, moderate adult size 1.2–1.8 metres (3.9–5.9 ft), attractive pattern, and comparatively simple care make them popular pet snakes. In the wild, they usually live around 15–20 years, but may live as long as 23 years in captivity.
