Snakes That Eat Other Snakes: 10 Ophiophagous Species You Need to Know
When most people picture a snake's predator, they think of raptors, mongooses, or large mammals. But some of the most effective snake hunters are snakes themselves. Known as ophiophagous snakes, these species have evolved remarkable adaptations for hunting some of the most dangerous animals on earth: partial resistance to potent venoms, specialized dentition for gripping fast and slippery prey, and hunting strategies that challenge everything we assume about reptile behavior.
Below you will find 10 snakes that eat other snakes, ranked by biological significance. Every fact here has been cross-checked against peer-reviewed literature and official scientific sources.

The 10 Snakes That Eat Other Snakes, Ranked
10 King Cobra (Ophiophagus hannah)
No species belongs on this list more naturally than the king cobra. Its scientific name says it all: Ophiophagus literally means "snake eater" in Greek. It also holds the record as the longest venomous snake in the world, with adults commonly measuring 3 to 4 meters and exceptional individuals exceeding 5 meters. For a deeper dive into its biology, see our king cobra facts guide covering size, venom, and survival odds.
A major taxonomic revision published in 2024 split what was long considered a single wide-ranging species into four distinct species. Under the updated classification, Ophiophagus hannah is now restricted mainly to populations from northern and eastern South Asia through parts of mainland Southeast Asia.
- Rat snakes, pythons, cobras, and kraits
- Smaller king cobras
- Some individuals specialize so narrowly that in captivity they will only accept one specific type of snake
Female king cobras are extraordinary among snakes because they actively build nests, pushing leaves, branches, and other vegetation into a mound before depositing roughly 20 to 40 eggs inside. Heat from decomposing plant material helps regulate temperature, and the female stays close to guard the clutch. Males have also been observed lingering near nesting sites.
King cobras hunt predominantly during the day, though activity can shift with environmental conditions. When threatened, they can raise approximately the front meter of the body off the ground, spread the hood, and move while holding that elevated posture. Despite their fearsome reputation, they typically prefer to retreat when given a clear exit. Hatchlings look strikingly different from adults: they are dark or nearly black with bright pale yellow or white crossbands on the body, tail, and head.
9 Malaysian Blue Coral Snake (Calliophis bivirgatus)
Also known as the long-glanded blue coral snake, this Southeast Asian elapid is immediately recognizable by its dark blue to black body, pale lateral stripes, and vivid red coloration on the head, belly, and tail. It might be small, but its venom system is one of the most unusual found in any snake.
The venom glands can extend through approximately one-quarter of the snake's entire body length, reaching well behind the head and deep into the rib cage. Nothing like this is seen in most elapids.
Its venom contains a three-finger toxin called calliotoxin that works through a mechanism completely different from the flaccid paralysis produced by typical elapid neurotoxins. Calliotoxin activates voltage-gated sodium channels and delays their inactivation, causing rapid muscle contractions and spastic paralysis in experimental preparations. Researchers believe this fast-acting system evolved specifically for capturing other snakes, which are dangerous and exceptionally quick prey.
Human bites are rare, but the venom is medically serious. At least one confirmed fatal envenomation has been recorded in the scientific literature.
8 Eastern Indigo Snake (Drymarchon couperi)
The eastern indigo snake holds the title of the longest native snake in the United States. The best-documented maximum length is approximately 2.6 meters, with mature males growing larger than females. Adults are heavily built and muscular, and their blue-black scales produce a striking iridescent sheen in sunlight. The chin and throat can be reddish, orange-brown, cream, or pale.
This species uses neither venom nor constriction. Instead, it overpowers prey with powerful jaws, sometimes pinning or working the prey before swallowing, or simply gulping it down alive. The diet is extraordinarily broad: frogs, fish, birds, mammals, turtles, lizards, and other snakes, including rattlesnakes. Eastern indigo snakes have documented physiological resistance to the venoms of sympatric North American pit vipers, allowing them to take prey that would kill most vertebrates.
Females can store viable sperm for extended periods. The U.S. Fish and Wildlife Service notes that sperm may remain fertile for potentially more than four years before fertilizing eggs. In the northern part of their range, gopher tortoise burrows are critical refuges used for overwintering, shelter, breeding, and nesting. Though generally calm, a threatened individual may hiss, flatten parts of its body, vibrate its tail rapidly against vegetation, or bite.
7 Banded Krait (Bungarus fasciatus)
The banded krait is one of those snakes you cannot misidentify: broad alternating black and yellow or cream bands run the length of the body, and an enlarged row of vertebral scales gives the back a distinctly triangular or ridged silhouette. It is among the largest members of the genus Bungarus, reaching lengths of approximately 2.25 meters.
This is a predominantly nocturnal hunter. During daylight hours the banded krait tends to stay hidden and relatively still; after dark it becomes noticeably more active. Other snakes are a major dietary component, and records include both venomous and non-venomous prey species. The diet also extends to lizards, amphibians, fish, and small mammals, so calling it an exclusive snake specialist would be inaccurate.
Banded krait venom carries potent pre- and postsynaptic neurotoxins that can disrupt neuromuscular transmission and ultimately cause respiratory paralysis. What surprises many people is that despite this dangerous venom, the species is notably reluctant to bite defensively compared with most other venomous snakes. Its nocturnal activity is about hunting and normal movement, not targeting humans.
6 Mussurana (Clelia clelia)
The mussurana is a large Neotropical snake found across parts of Central America, South America, and the Caribbean. Adults are typically dark brown to black, while juveniles often look quite different in color. It is an opisthoglyphous (rear-fanged) snake, meaning its venom delivery teeth sit at the back of the upper jaw rather than at the front.
It is perhaps best known for hunting pit vipers, particularly species in the genus Bothrops. The mussurana's blood contains factors that inhibit key components of viper venom, giving it substantial natural resistance that allows it to tackle prey far too dangerous for most other animals. This resistance is real and significant, but it is not absolute immunity since biological resistance and complete invulnerability are not the same thing. The species subdues prey with a combination of biting and body restraint or constriction. It is oviparous, reproducing by laying eggs.
5 Painted Coral Snake (Micrurus corallinus)
The painted coral snake is a brilliantly banded South American elapid closely associated with Brazil's Atlantic Forest. Its red, black, and pale bands serve as aposematic (warning) coloration, signaling danger to potential predators.
Contrary to a common assumption, dietary studies of Micrurus corallinus reveal that much of what it eats is not other snakes but elongated burrowing animals. One detailed dietary study identified amphisbaenians as the dominant prey, followed by lizards, caecilians, and snakes.
Its venom is highly neurotoxic. Proteomic analysis found the composition to be approximately 81.7% three-finger toxins and 11.9% phospholipase A₂ enzymes, with smaller fractions of additional toxin families. Severe envenomation can progress to paralysis of the respiratory muscles. The species is secretive, spending most of its time concealed under vegetation or underground. It is oviparous, with documented clutch sizes generally ranging from about 2 to 12 eggs.
4 Common Kingsnake (Lampropeltis getula)
The common kingsnake is one of the most studied snake predators in North America. Its coloration varies across its wide range, but many populations sport a dark body patterned with pale chain-like bands. It is non-venomous and handles some of the continent's most dangerous snakes through constriction, not venom resistance alone.
Documented prey includes rattlesnakes, copperheads, cottonmouths, and in some regions coral snakes. Research has shown that Lampropeltis getula generates exceptionally effective constriction pressure relative to its body size, making it one of the more powerful constrictors for its weight class. The species also carries substantial physiological resistance to the venoms of several pit viper species, though this resistance is not universal or absolute across every venom type and dose. For more on rattlesnake biology, see our rattlesnake facts page.
The diet is genuinely opportunistic and includes rodents, lizards, birds, eggs, amphibians, and other vertebrates alongside snakes. When threatened, kingsnakes hiss, strike, release foul-smelling musk, and vibrate their tails rapidly. The tail vibration against dry vegetation can mimic the sound of a rattlesnake, even though the kingsnake has no rattle. In captivity with proper care, individuals can live for more than two decades.
3 Coachwhip (Masticophis flagellum)
The coachwhip is an extremely slender, fast-moving North American snake whose braided-looking tail inspired both its common and scientific names. Published speed estimates place its maximum at around 5.8 kilometers per hour approx. 3.6 mph, making it one of the quickest snakes on the continent. It relies entirely on speed, sharp eyesight, and powerful jaws to secure prey, with no venom and no constriction.
Coachwhips are active visual hunters. They scan constantly while moving and will take lizards, other snakes, insects, birds, eggs, and occasionally small mammals or amphibians. They are capable of eating venomous snakes but function as generalist predators rather than dedicated rattlesnake hunters. A distinctive behavior called periscoping involves raising the head and front of the neck above surrounding vegetation to survey the landscape before moving.
Radio-tracking work in some populations has measured average home ranges of approximately 56 hectares, though the core areas used most intensively are considerably smaller.
2 Cottonmouth (Agkistrodon piscivorus)
The cottonmouth is a heavy-bodied, semiaquatic pit viper native to the southeastern United States. Its common name comes from the bright white interior of the mouth, which it opens wide during its characteristic threat display.
Few North American snakes eat as wide a variety of prey. The cottonmouth takes fish, frogs, salamanders, mammals, birds, turtles, other snakes, carrion, and individuals of its own species (cannibalism is documented). Female cottonmouths are among the snake species where facultative parthenogenesis has been recorded, meaning reproduction can occasionally occur without genetic contribution from a male, though this appears to be an unusual circumstance rather than the norm.
The venom contains enzymes and toxins that can produce significant pain, swelling, bruising, and local tissue injury in serious cases. Despite its aggressive reputation, the cottonmouth is a defensive animal, not a human pursuer. It gapes, coils, vibrates its tail, or retreats when confronted, and does not deliberately chase people. It is an accomplished swimmer and moves efficiently both on the surface and underwater. For a broader look at dangerously venomous snakes, see our guide to the most dangerous vipers in the world.
1 Snake-Eater Wolf Snake (Lycodon ophiophagus)
Lycodon ophiophagus was formally described as a new species in 2009 during a taxonomic revision of the Lycodon ruhstrati species complex. It is known from southern Thailand, specifically from areas around the provinces of Chumphon, Ranong, and Phang-Nga, giving it one of the most restricted ranges of any species on this list.
The species epithet ophiophagus, like the king cobra's genus name, comes from Greek roots meaning snake-eater, and the name reflects its documented predatory behavior. The body is dark with approximately 20 to 21 pale crossbands. The upper jaw features enlarged posterior maxillary teeth separated by characteristic gaps, one of the key anatomical traits researchers use to distinguish it from closely related wolf snakes.
Wolf snakes in the genus Lycodon are colubrids and are not considered medically significant to humans, though a defensive bite from any snake handled carelessly is always possible. The species is oviparous, reproducing by laying eggs.
Frequently Asked Questions About Snakes That Eat Other Snakes
What does it mean for a snake to be ophiophagous?
An ophiophagous snake is one that regularly eats other snakes. The word combines the Greek ophis (snake) and phagein (to eat). Some species are narrow specialists, like the king cobra; others include snakes as part of a wider, more opportunistic diet.
Are snakes that eat venomous snakes immune to venom?
Not fully. Several species that prey on venomous snakes have documented partial physiological resistance to the venoms of their typical prey, but this is not the same as total immunity. Kingsnakes, mussuranas, and eastern indigo snakes show measurable resistance to certain pit viper venoms, yet that protection has limits and does not extend to every type or dose of venom.
What is the most dangerous snake that eats other snakes?
For humans, the king cobra (Ophiophagus hannah) is the most dangerous species on this list. It is the world's longest venomous snake, and envenomation can be fatal without timely medical treatment.
Do kingsnakes really kill rattlesnakes?
Yes, and quite effectively. Common kingsnakes (Lampropeltis getula) are well-documented predators of rattlesnakes, copperheads, and cottonmouths. They use constriction to subdue these dangerous prey animals and carry partial physiological resistance to pit viper venom. Research confirms they generate unusually effective constriction pressure for their body size.
Which snakes in the United States eat other snakes?
Several North American species regularly include snakes in their diet. The common kingsnake (Lampropeltis getula) and the eastern indigo snake (Drymarchon couperi) are the most dedicated examples, with both being documented predators of venomous species. The coachwhip (Masticophis flagellum) and the cottonmouth (Agkistrodon piscivorus) also eat snakes, though they are generalist feeders rather than specialists.
Does the king cobra eat only snakes?
Snakes form the bulk of the king cobra's documented diet, including rat snakes, pythons, cobras, kraits, and smaller king cobras. Its diet is not restricted to snakes alone, however. Some individuals specialize so thoroughly that in captivity they will consistently accept only one specific type of snake as prey.
