25 Cool Facts About King Snakes

What Makes King Snakes So Special?

King snakes are some of the most fascinating reptiles in North America. They get their royal name because they actually eat other snakes, including venomous ones like rattlesnakes and copperheads. That alone makes them pretty incredible, but there is so much more to learn about these amazing creatures.

Whether you are thinking about getting a king snake as a pet or you just spotted one in your backyard, here are 25 cool facts that will change the way you look at these snakes.

They Eat Other Snakes (Even Venomous Ones)

This is the number one reason king snakes earned their name. They regularly hunt and eat other snakes, and they have a natural resistance to the venom of pit vipers like rattlesnakes, copperheads, and cottonmouths. When a king snake encounters a venomous snake, it will grab it behind the head and constrict it just like it would any other prey. The venom that would be deadly to most animals barely affects them.

King Snakes Are Constrictors

Rather than using venom to subdue their prey, king snakes are powerful constrictors. They wrap their muscular bodies around their prey and squeeze until the animal can no longer breathe. Pound for pound, king snakes are actually some of the strongest constrictors in the snake world. Their squeezing power relative to their size is impressive, even compared to much larger species like boas and pythons.

There Are Multiple Species and Subspecies

The term “king snake” actually covers several different species and many subspecies. The most well known include the California king snake, the Eastern king snake, the Mexican black king snake, and the speckled king snake. Each one has its own unique color pattern and range, but they all share that signature king snake toughness and appetite for other reptiles.

They Come in Amazing Color Patterns

King snakes are some of the most colorful snakes you will find. Depending on the species and region, they can have bands, stripes, speckles, or solid coloring. California king snakes often have bold black and white bands. Eastern king snakes tend to be dark with chain like patterns. Some king snakes even mimic the coloring of coral snakes, using red, black, and yellow bands to scare off predators.

They Are Found All Across North America

King snakes have a huge range. You can find different species from southern Canada all the way down through Mexico. They live in deserts, forests, grasslands, swamps, and even suburban neighborhoods. Their ability to thrive in so many different environments is one of the reasons they have been so successful as a species.

King Snakes Are Not Venomous

Despite being fearless predators that eat venomous snakes, king snakes themselves are completely non venomous. They pose no danger to humans at all. If a king snake bites you (which is rare unless you are handling one roughly), it might draw a tiny bit of blood, but there is no venom to worry about. This is one of the reasons they make such popular pets.

They Are Great Beginner Pet Snakes

If you are thinking about getting your first snake, a king snake is one of the best choices out there. They are generally docile, easy to handle, and not too picky about food. Most king snakes do well with a simple setup and regular feeding of appropriately sized mice. They also come in a wide variety of color morphs for those who want something unique looking.

King Snakes Are Immune to Pit Viper Venom

Scientists have studied this extensively and confirmed that king snakes produce special proteins in their blood that neutralize pit viper venom. This immunity is not complete against all snake venoms, but it works very well against the rattlesnakes, copperheads, and cottonmouths that share their habitat. This adaptation gives king snakes a huge advantage in the wild.

They Vibrate Their Tails When Threatened

When a king snake feels threatened, it may vibrate its tail rapidly against the ground or dry leaves. This creates a buzzing sound that can be mistaken for a rattlesnake. It is a clever defense strategy that makes predators think twice before attacking. Many non venomous snakes use this trick, but king snakes are especially good at it.

They Can Live 15 to 25 Years in Captivity

With proper care, a pet king snake can live for a very long time. Most king snakes in captivity live between 15 and 25 years, with some individuals reaching even older ages. That is a serious commitment, so make sure you are ready for a long term relationship before bringing one home. In the wild, they tend to live shorter lives due to predators and environmental hazards.

King Snakes Are Mostly Nocturnal

In the wild, king snakes tend to be most active during the early morning and late evening hours. During the hottest part of the day, they usually hide under rocks, logs, or in burrows to stay cool. In cooler weather, you might see them out basking in the sun during the day. Pet king snakes often adjust their schedule somewhat to match their feeding routine.

They Are Excellent Escape Artists

If you keep a king snake as a pet, invest in a secure enclosure with a tight fitting lid. King snakes are notorious for finding the smallest gaps and squeezing through them. They are strong, flexible, and incredibly determined when they want to explore. A loose fitting screen top or an unlocked door is basically an open invitation for a king snake to go on an adventure through your house.

They Eat a Varied Diet in the Wild

King snakes are not picky eaters. In the wild, they eat rodents, birds, bird eggs, lizards, frogs, turtle eggs, and of course other snakes. This varied diet makes them adaptable survivors that can thrive in many different environments. In captivity, they do well on a diet of appropriately sized mice or rats.

Baby King Snakes Are Independent From Birth

Mother king snakes lay their eggs and leave. There is no parental care at all. When baby king snakes hatch, they are fully equipped to hunt and survive on their own. Hatchlings are usually about 8 to 12 inches long and will start hunting small lizards and baby mice almost immediately. They are tiny but fierce right from day one.

They Lay Eggs Rather Than Give Live Birth

King snakes are oviparous, which means they lay eggs. A female king snake typically lays between 3 and 24 eggs per clutch, depending on her size and species. The eggs are usually deposited in a warm, hidden spot like under a log or inside a rotting stump. After about 50 to 80 days of incubation, the babies hatch out ready to go.

California King Snakes Are the Most Popular Pet Variety

Among all the king snake species, the California king snake is by far the most popular choice for pet owners. They are widely bred in captivity, come in dozens of stunning color morphs, and tend to have calm temperaments. You can find California king snakes in everything from the classic black and white banded pattern to solid chocolate brown, lavender, and even banana yellow.

They Brumate During Winter

Like many reptiles, king snakes go through a period of brumation during the colder months. Brumation is similar to hibernation but for reptiles. They slow down dramatically, stop eating, and find a sheltered spot to wait out the cold. This period is actually important for breeding, as many king snakes need a cooling period to trigger their reproductive cycle in the spring.

King Snakes Have Been Known to Eat Rattlesnakes Twice Their Size

There are documented cases of king snakes taking on and eating rattlesnakes that were significantly larger than themselves. A king snake’s flexible jaw and expandable body allow it to swallow prey much bigger than its own head. Combined with their venom immunity, this makes them one of the few animals that rattlesnakes actually need to fear.

They Musk When Scared

If a king snake is picked up and feels scared, it might release a foul smelling musk from glands near its tail. This is a common defense mechanism in many snake species. The smell is pretty unpleasant and is meant to convince a predator to drop the snake. Pet king snakes usually stop musking once they get used to being handled regularly.

Some King Snakes Mimic Coral Snakes

Several king snake species have evolved color patterns that closely resemble the deadly coral snake. This is called Batesian mimicry, where a harmless species copies the appearance of a dangerous one. The classic rhyme “red touches yellow, kills a fellow; red touches black, friend of Jack” was created to help people tell the difference between venomous coral snakes and harmless king snake mimics.

They Are Solitary Animals

King snakes prefer to live alone. In the wild, they only come together during mating season. If you keep king snakes as pets, you should never house two together. King snakes are known to eat other snakes, and that includes other king snakes. Housing two together can end very badly for one of them, regardless of how well fed they are.

King Snakes Have Smooth Scales

Unlike some snake species that have rough or keeled scales, king snakes have smooth, glossy scales that give them a sleek, polished appearance. Their smooth scales make them pleasant to handle and contribute to their attractive look. The shine of a healthy king snake’s scales after a fresh shed is really quite beautiful.

They Play an Important Role in the Ecosystem

King snakes are valuable members of their ecosystems. By eating rodents, they help control populations that could otherwise damage crops and spread disease. By eating venomous snakes, they help keep those populations in check too. Farmers and ranchers often consider king snakes beneficial and welcome their presence on their property.

King Snakes Can Grow 3 to 6 Feet Long

Most king snake species reach between 3 and 4 feet as adults, though some species like the Eastern king snake can grow up to 6 feet. Their size makes them manageable as pets while still being impressive looking. A full grown king snake is a beautiful animal that is easy to handle and fun to watch.

They Are One of the Easiest Snakes to Breed

For reptile breeders, king snakes are among the most straightforward snakes to breed in captivity. With proper brumation, a healthy male and female will usually breed successfully. The eggs incubate well at standard temperatures, and hatchlings tend to be strong and feed easily. This is why there are so many stunning captive bred color morphs available today.
