When it comes to making a decision between a corn snake and a king snake, both are excellent choices for the beginner reptile keeper. They are both non-venomous and make great pets that are easy to handle. But there are striking differences between the two.

Corn snakes are often more colorful and have more eye-catching patterns. They come in various colors, including oranges and reds with black splotches. King snakes are more muted in color, ranging from browns and blacks. The patterns are not as elaborate as those of the corn snake.

The differences between a corn and a king snake also extend to size, habitat, origin, appearance, how they feed, temperament, and lifespan. Read on for in-depth information about how these two snakes stack up against each other.

Key Differences Between a Corn Snake and a King Snake

Key differences between a corn snake and a king snake must be considered when deciding which pet snake is right for you. Here are the main differences between the two:

Origin

Corn snakes, also known as Pantherophis guttatus, form a family of snakes known as Colubridae, while king snakes, also known as Lampropeltis getula, belong to the family of Lampropeltis. 

Colubridae is the largest family of snakes, including over two-thirds of all snake species. Lampropeltis is a genus that includes more than 23 species of kingsnakes. Corn snakes and king snakes originated in the United States. Corn snakes live in southern states from New York to Florida, while king snakes inhabit the western states from Florida to California. 

Corn snakes are mostly terrestrial, while king snakes are primarily arboreal. The two species are non-venomous and can live in relatively close proximity, but they are not typically found living together. 

Size

The corn snake is the smaller of the two, usually reaching an adult size of 24-72 inches (61-82 cm) in length. On the other hand, the king snake is a bit larger, reaching an adult size of 36-72 inches (91-183 cm).

Although it may vary as the male and females have different maturity sizes. The females are typically longer than the males. Where a female can grow up to 72 inches (183 cm), a male can only reach up to 42 inches (106 cm).

The corn snake also tends to be lighter than the king snake. It can weigh anywhere from 25 to 32 ounces (700-900 g), whereas the king snake can reach up to 77 ounces (2,183 g).

Temperament 

Corn snakes tend to be more skittish, docile, and calm, while king snakes can be more aggressive. King snakes are natural predators and will attempt to stay on top of their food sources.

Corn snakes are relatively calm when handled, and even in the wild, they are more likely to flee than fight. They tend to freeze in a defensive posture when disturbed and only bite as a last resort. 

King snakes can display striking defensive behavior when threatened, flaring their necks and hissing loudly. While this is intimidating, they rarely bite unless provoked.

Feeding

The corn snake and king snake are opportunistic feeders, so their diet will consist of mice and small rodents. Corn snakes prefer smaller prey, such as pinkies and fuzzy mice. They are small in size and have smaller mouths. 

But King snakes will typically take larger prey, such as rats and rabbits, due to their larger size and powerful jaws. You should note that both species should have their food pre-killed to reduce the risk of injury or harm to your pet.

When it comes to their feeding habits, both the corn snake and king snake tend to be easygoing. Corn snakes have a reputation for being very gentle and docile eaters, whereas kingsnakes are known to be more aggressive and eager when it comes to their food. As long as the prey is small enough to swallow, they’ll happily take it. 

Appearance

The corn and king snakes are both relatively similar, with slender bodies, round pupils, and keeled scales. The main difference between their appearances is in the color and patterning.

The corn snake is often brightly colored, with a red or orange base color and numerous black spots, known as the “corn snake pattern.” 

The king snake’s color range is usually muted browns and blacks and lacks the standout corn snake pattern. In terms of markings, the king snake tends to have stripes down its back and sides, whereas the corn snake does not. 

The corn snake does have a distinctive pattern that includes large black spots, which can vary in number and size. It’s also worth noting that both species can come in different colors, patterns, and morphs. 

Corn snakes are usually more colorful and have more intricate patterns, which is why they are often mistaken for the venomous coral snake.

Lifespan

Corn and king snakes’ lifespans can vary significantly depending on the environment in which they are kept. On average, a corn snake will live between 10-15 years. A king snake will typically live for around 15-20 years in captivity but can reach up to 30 years in ideal conditions. 

King snakes can live for around 5-10 years in the wild. The age at which these snakes reach maturity also differs between species. Corn snakes reach adulthood at 2-3 years, while king snakes require up to 5 years before they are considered adults. 

Habitat

Corn snakes and kingsnakes both inhabit a variety of habitats. Corn snakes are commonly found in the southeastern United States, from New Jersey to Florida. They inhabit tropical hammocks, barns, woodlots, wooded groves, meadowlands, fields, rocky hillsides, and other semi-open areas. 

Corn snakes are primarily terrestrial species but can occasionally climb trees for food or shelter.

Kingsnakes, on the other hand, can be found in almost any habitat across the United States and parts of Mexico, from deserts and grasslands to oak woodlands and subtropical forests. 

They can even be found in urban areas. They do best in habitats with rocky and sandy soils and plenty of cover for hiding during the day.

Benefits of Keeping Corn Snakes and King Snakes as Pets

Both corn snakes and king snakes make excellent pets. They are generally quite docile and easy to handle, making them ideal for beginners. They are also relatively low-maintenance, requiring only a few simple supplies and occasional feedings. 

They can even be kept in smaller enclosures than many other species as long as the environment is kept warm and humid. Corn and king snakes are also fascinating to watch, with their colorful patterns and curious personalities. 

And since they are non-venomous, owners can feel safe handling their pets without fear of being bitten. Keeping a corn snake or king snake as a pet can be an incredibly rewarding experience and is sure to bring plenty of joy. 

Final Thoughts

These two species may look similar, but various factors set them apart. Corn snakes and kingsnakes have different feeding habits, lifespans, origins, and habitat preferences. 

Each species makes an excellent pet, as they are gentle, docile, and easy to care for. Whether you’re looking for an exotic pet or a unique conversation piece, one of these beautiful snakes would be a great addition to your home.
