Pantherophis guttatus, commonly known as the corn snake, is a non-venomous colubrid species native to North America. It is one of the most well-known and widely kept snake species in captivity, prized for its striking colors, docile temperament, and ease of care. Corn snakes are medium-sized, typically reaching lengths of 3 to 5 feet (90 to 150 cm), with some individuals growing larger. They possess a slender, muscular body, a distinctive head shape, and a pattern of dorsal blotches that help them blend into their natural surroundings.
Corn snakes are primarily terrestrial but are also adept climbers. They are found in a variety of habitats, including forests, grasslands, rocky outcrops, and even abandoned buildings and barns. Their adaptability and ability to thrive in human-altered landscapes contribute to their widespread distribution.
These snakes are constrictors, meaning they subdue their prey by coiling around it and suffocating it before swallowing it whole. Their diet mainly consists of small rodents, birds, and amphibians. Because of their natural role in controlling rodent populations, they provide ecological benefits in the wild.
Corn snakes are popular in the pet trade due to their ease of care, gentle nature, and wide range of color morphs developed through selective breeding. Unlike venomous species often mistaken for them, such as copperheads, corn snakes pose no threat to humans and make excellent pets for both beginner and experienced reptile enthusiasts.
Common Names and ClassificationCorn snakes belong to the family Colubridae, which is the largest family of snakes, encompassing over 1,800 species. Their classification is as follows:
Previously, corn snakes were classified under the genus Elaphe and were known as Elaphe guttata. However, genetic studies led to taxonomic revisions, moving them to the genus Pantherophis, which includes several North American rat snakes.
Common NamesCorn snakes are known by several common names across different regions. The most widely used name, "corn snake," is believed to have originated from the pattern on their ventral scales, which resembles kernels of Indian corn. Another theory suggests that their frequent presence in grain stores and barns, where they prey on rodents, contributed to the name.
Some of the other common names include:
The variety of names reflects both the species' appearance and its relationship with human habitats.
