Meet the King Snake: A non-venomous reptile that hunts and eats venomous snakes; here's how it kills its prey

Meet the king snake, a non-venomous reptile found across North America that has earned a reputation as one of the most unusual predators in the animal kingdom, not for producing venom, but for hunting and eating snakes that do.

Rattlesnakes, cottonmouths, copperheads: these are the kingsnake's prey. That ability, combined with a biological resistance to pit viper venom, is what gave this snake its name.

How does a non-venomous snake kill venomous ones?


The king snake does not use venom. It belongs to the Lampropeltis genus and is a constrictor, meaning it kills by coiling around prey and squeezing until the animal suffocates.

When targeting another snake, the king snake relies on speed, strength and timing to overpower it before it can strike back effectively. Its resistance to pit viper venom gives it a significant advantage, allowing it to take on prey that would be lethal to most other animals.

The practice of snakes eating other snakes has a name: ophiophagy. Among North American reptiles, the kingsnake is among the most well-known practitioners of it.

What else does the kings nake eat?

Venomous snakes are not the only item on the menu. King snakes also eat lizards, rodents, birds, bird eggs and amphibians, which makes them adaptable hunters across a wide range of habitats and seasons.

What does a king snake look like?

King snakes are slender-bodied with vivid patterns that vary considerably across species and subspecies. Some are banded in ways that resemble coral snakes or other brightly marked reptiles, a similarity that has made them a subject of folklore and field guides for decades.

Unlike coral snakes, however, kingsnakes produce no venom. Their reputation comes from their predatory behaviour, not their appearance.

Where do king snakes live?

King snakes are found coast to coast across North America, from the southeastern United States into parts of Canada and through Mexico and Central America. Different species have adapted to different environments, which is why they turn up across such a broad range of habitats.

They are known to inhabit rock outcrops, brushy hillsides, river valleys, woodlands, fields, pine forests and wetland edges. In Tennessee, wildlife guidance notes that common kingsnakes are frequently found under logs, boards and debris, around streambanks and wetlands, and occasionally on stone walls and in barns.

In the western United States, California kingsnakes are associated with woodland, chaparral and rocky streambeds.

Where are the best places to spot a king snake?

For wildlife watchers, the southeastern United States offers reliable sightings of species such as the eastern kingsnake, found in sandy uplands, pine flatwoods, mixed forests and river floodplains.

In the west, California kingsnakes are secretive but can be found in areas with plentiful cover and sunlight, particularly along rocky streambeds and woodland edges.

Generally, the best spots are sunny natural areas with nearby cover: streambanks, forest edges, rocky slopes and debris piles where snakes shelter during the hottest part of the day.

When is the best time to look for king snakes?

King snakes are most active in warm weather, particularly in spring and early summer, when they are out hunting more frequently. Wildlife watchers are advised to move slowly, stay quiet and scan carefully around rocks, logs and brush.

Flipping rocks or disturbing habitat is discouraged, both for observer safety and the snake's welfare. Kingsnakes are generally not aggressive toward people but can bite if cornered or handled. Observation from a distance is recommended.

Why do king snakes matter in the wild?

King snakes help regulate populations of rodents and other snakes, including venomous species, making them an active part of the food web in the habitats they occupy. By preying on venomous snakes, they contribute to a natural balance that benefits broader ecosystems.
