Discover the Largest Corn Snake Ever Recorded

Corn snakes are colorful snakes native to the southeastern United States. These snakes are a North American species of rat snake. In some areas people call them “red rat snakes” because of their bright red, orange, and yellowish-brown colors. Sometimes people mistake wild corn snakes for venomous copperhead snakes. However, not only are corn snakes calm and docile, but they are nonvenomous and completely harmless to humans.

In fact, corn snakes are very popular pets, and come in a seemingly infinite range of different colors. These snakes usually don’t grow more than 4 feet long in captivity, but of course, there have been many corn snakes that were much longer. So, just how long is the largest corn snake ever recorded?

What do Corn Snakes Look Like?

In the wild, corn snakes are usually red, orange, or a brownish-yellow color. There are red blotches with black edges that run along the length of their bodies. Young corn snakes are typically darker and have more brown tones. As they age, their colors brighten. Depending on their age and where they live, the colors and patterns of corn snakes will vary. Pet corn snakes, on the other hand, have been selectively bred and come in an endless array of different colors, morphs, and patterns. Corn snakes are usually between 24-48 inches in length, although the longest corn snake ever recorded was much longer.

The head of a corn snake typically has a spear-shaped blotch on top. Their bellies have bold black and white alternating checkerboard-like patterns. Some say that this uniquely patterned belly looks like variegated corn, which is where the corn snake gets its name. However, another theory is that the corn snake got its name because it spends time in corn fields, as well as in barns near grain storage and corn feed. Corn snakes are common both in barns and agricultural fields where they hunt mice and rats.

Those who are unfamiliar with these snakes can sometimes mistake a harmless corn snake for the venomous copperhead snake. However, corn snakes and copperhead snakes are actually very different in appearance. It is important to become familiar with these snakes so that both you and the snakes can stay safe. Here are a few distinct differences between corn snakes and copperhead snakes:

  • Copperhead snakes have even blotches shaped like an hourglass running along the length of their bodies.
  • Corn snakes also have blotches along the length of their bodies. However, these markings are random and do not have a uniform shape.
  • Copperhead snakes do not have the iconic black and white checkered belly that corn snakes are famous for.

Of course, if you see either of these snakes in the wild, it is always best to leave it alone, no matter what species it is.

What is the Largest Corn Snake Ever Recorded?

Corn snakes can be anywhere between 24-72 inches in length, although most do not grow longer than 48 inches. However, the largest corn snake ever recorded was 74 inches long!

In general, female corn snakes grow larger than males. The length of the largest corn snake is comparable to another snake species found in the Southeastern United States: the black racer. Similar to the largest corn snake, black racers have a maximum length that’s slightly longer than 6 feet long. It’s worth noting that the largest copperhead ever measured was just 4 feet 5 inches (53 inches). While copperheads aren’t as lengthy as the longest corn snakes, they are wider.

Baby corn snakes, on the other hand, are only 10-15 inches long when they are born. Corn snakes are oviparous and lay their eggs from late May through July. Female corn snakes lay 10-30 eggs in hidden areas with plenty of humidity and heat, like decaying vegetation and rotting stumps. Baby corn snakes hatch between July and September and are completely independent as soon as they emerge from their shells.

Where do Corn Snakes Live?

Outside of the United States corn snakes are often called “American Corn Snakes.”

Corn snakes are native to the southeastern United States. There are especially high numbers of these snakes in Florida, where they are a species of special concern. State laws in Georgia also protect wild corn snakes.

In addition, corn snakes have more recently been observed in areas outside of the United States, possibly from escaped pets that adapted back to the wild and reproduced. Corn snakes are extremely adaptable and can adjust to many different types of environments. Observers report established populations of corn snakes on some of the Caribbean islands, the Bahamas, the U.S. Virgin Islands, and even Australia.

Corn snakes often live on rocky hillsides and open areas, as well as woodlands, meadows, longleaf pine forests, tropical hammocks, and flatwoods. Many corn snakes will even move into abandoned buildings and barns where mice and rats are plentiful. When it gets too hot in the summer, corn snakes often seek shelter in cooler areas under logs, sheet metal, and wood boards, as well as in rodent burrows and stump holes.

They will usually attempt to flee or intimidate before ever striking.

Because of their popularity as pets and selective breeding, there are now over 800 different color morphs and variations of these snakes. Natural colors seen in “wild” corn snakes are common of course, such as brown, yellowish-brown, grey, and orange, with dark blotches along the length of the snake’s body. Motley color morphs, on the other hand, have the opposite pattern of wild corn snakes. Instead of the iconic black and white checkered pattern of wild corn snakes, Motley corn snakes have a plain white belly. Patterns along the snake’s back are smaller and fainter as well.

Albino corn snakes are also popular, with light pink and cream bodies and red eyes. Another morph, the Hypomelanistic corn snake, has little to no black coloring on its scales. Striped corn snakes come in a wide variety of colors, with well-defined stripes running vertically along the length of their bodies instead of spots or blotches. Lavender corn snakes are quite popular as well. When they are born these snakes are grey, but as they age their scales transition into a light lavender color with silver botches.

Of course, these are only a handful of the many, MANY different types, colors, and patterns of pet corn snakes out there. Whatever color you can imagine, you can probably find a pet corn snake to match.
