The kingsnake is a part of the colubrid New World and is of the Lampropeltis genus. This snake has 45 subspecies, and they are all nonvenomous. The kingsnake is the most common snake in North America. Some of its subspecies, like the Mexican kingsnake and red kingsnake, can often be confused with a coral snake, which is highly venomous. Therefore, it’s important to pay attention to the pattern of their scales when out in nature. While some snakes of this species can be as small as 24 inches, others can grow up to 60 inches in length! So, what is the largest kingsnake ever recorded? Let’s find out.

Many of the kingsnakes and their subspecies typically range anywhere from 3 to 4 feet in length. In 2021, at Agoura Hills in Southern California, conservation workers identified a California kingsnake that had an estimated measurement of 7 feet. The snake was seen slithering towards a busy road. This makes it the largest ever recorded!

Is It Normal for a Kingsnake to Be This Big?

No! Kingsnakes are usually 3-4 feet long and reach a maximum length of 5 feet. That makes this 7-foot-long snake even more amazing!

Kingsnakes can be found in a wide range of sizes, colors, and patterns. Their length typically ranges from 24 inches to 60 inches. They come in many different shades, from muted browns to black, white, red, yellows, grays, and lavenders. These colorations are usually organized into rings, longitudinal stripes, speckles, or saddle-shaped bands that give them unique appearances. They also have a variety of head shapes, including triangular with pointed snouts or round heads with blunt snouts, depending on the species.

About Kingsnakes

Appearance and Behavior

Almost all kingsnakes are vibrant in color, however, appearance often changes depending on habitat. While a Mexican black kingsnake is pure black with black bellies, a red kingsnake is red with black and white stripes. The Mexican kingsnake is similar, but the red in their scales can sometimes be darker. Also, their stripes are yellow in color, often confusing them with the poisonous coral snake.

A straightforward way to distinguish the two is to look at the pattern in their scales. A Mexican kingsnake has yellow stripes that are in between two black stripes, while the coral snake has yellow stripes more prominently throughout its body. Their temperament is usually quiet and skittish, most of them often fleeing at the sight of a threat. In fact, there are several types that often play dead when threatened!

How Long Do Kingsnakes Live?

A kingsnake will often be able to mate between the ages of two to four years. In the wild, they are often hunted by birds and sometimes tarantulas depending on the size. Even with the threat of becoming prey, this snake is said to live up to 15 years in the wild. These snakes are extremely popular house pets and can live anywhere between 20 to 30 years when held in captivity.

While they can live a long time in captivity, they are a long-term commitment and require proper care to thrive as a household pet. This means an adequate diet and enclosure. In fact, the most popular kingsnake that is kept as a household pet is the Mexican black variety. This is because they can adapt easily and often become docile with their owners. Not to mention they are simply incredible to look at!

Kingsnakes can live for up to 15 years in the wild, and even longer if well cared for in captivity.



Even though these snakes aren’t venomous, they can still eat other venomous snakes. The common kingsnake is known to be resistant to some venom, often eating rattlesnakes because of this unique ability.

Kingsnakes kill their prey by constriction, often trapping many lizards, rodents, and birds with their little, but strong bodies. The California kingsnake has been known to exert twice the amount of force relative to its body size when constricting its prey. When they constrict, it will lower blood oxygen levels in their prey. The prey will die by asphyxiation before it is swallowed.

Where Do Kingsnakes Live?

Kingsnakes are quite common in North America, often ranging anywhere between the United States and Mexico. You can find this snake and its subspecies almost anywhere in North America, such as mountains, grasslands, rocky areas, and deserts. Some of these snakes can also live in wetter areas like swamps and riverbanks. This is particularly true for the eastern kingsnake and the speckled kingsnake. They are primarily terrestrial snakes; however, they can climb and have often proved to be very decent swimmers.

Is It Normal For Kingsnakes To Attack Humans?

Kingsnakes are not typically a threat to humans. This is because they retreat quite often when they feel scared. However, you will know if one of these snakes is aggressive and ready to bite. It warns you through a series of hissing sounds and puffing up of its body. They only fight back if they feel cornered, so make sure to give them space both in the wild and in captivity. Juveniles are more likely to be seen as a source of prey, which is why it is difficult to record their lifespan in the wild.

Kingsnake vs. Rattlesnake: The Differences

There are a few major differences between kingsnakes and rattlesnakes. For one, kingsnakes are non-venomous and relatively harmless snakes found in dry deserts or humid forests, depending on the specific species. In contrast, rattlesnakes are venomous, known for their distinctive rattling tail, and they prefer hot and dry desert climates.

Because they are non-venomous, kingsnakes must use constriction in order to kill their prey. Rattlesnakes have the advantage, in that they can use their powerful venom to incapacitate their meals.

In Conclusion

Kingsnakes are truly fascinating snakes. Their striking appearance is just one reason why they are known to be popular house pets. They are not endangered in North America. However, some of the subspecies are decreasing in population over time. The Todos Santos Island kingsnake is said to be critically endangered. Scientists in Florida are also concerned about the conservation of eastern kingsnakes due to their decreasing numbers in the population.

Thankfully in some states, such as Georgia, these amazing animals are protected under Conservation Acts. If you ever see one of these snakes while you’re out, give them space and allow them to continue with their day!

Other Record-Breaking Snakes

The eastern indigo snake is one of the largest nonvenomous snakes in North America, known for its glossy blue-black coloration and impressive size. If you’re curious about the largest eastern indigo snake ever recorded, there are a few interesting facts to consider.

Firstly, these snakes can grow up to 8 feet long and weigh up to 11 pounds. However, not all eastern indigo snakes reach these maximum sizes – some may only grow to be around 6 feet long or weigh less than 5 pounds.

That being said, the largest documented eastern indigo snake on record was an impressive specimen measuring over 9 feet long! This individual was found in Georgia back in the early 2000s and weighed nearly 20 pounds – making it significantly larger than most other members of its species.

Of course, part of what makes this particular snake so fascinating is how rare it is to find such a large individual. Eastern indigo snakes typically inhabit forests and wetlands across the Southeastern United States but are considered threatened due to habitat loss and fragmentation. As such, seeing one of these incredible creatures out in the wild can be a once-in-a-lifetime experience!
