40 free King Cobra trivia questions with answers — trivia quiz, new questions added Oct 2026.
Few animals carry a reputation like the king cobra. It can raise its hood to the height of a standing person, its bite is a medical emergency, and yet the animal behind the legend is shyer, stranger and more interesting than the horror stories suggest. This quiz collects the fun facts people actually look for: how big the snake gets, what it hunts, how its venom works, how it raises its young, where it lives in the wild and how scientists now classify it. There are questions on its senses, its defensive display and its long history with snake charmers, shrines and folk belief. It is written for curious readers, students, teachers and reptile fans alike. Every answer comes with a short explanation, so you will finish knowing more about the species than when you started.

Q 01What makes up most of a wild king cobra's diet, as the Greek meaning of its genus name Ophiophagus suggests?
Other snakes
Other snakes are the king cobra's main prey, venomous species included, and adults have even been recorded eating smaller king cobras.
Q 02A single king cobra bite can deliver enough venom to kill 20 people or which huge land animal?
An elephant
An elephant can be killed by one king cobra bite, not because the venom is unusually strong drop for drop but because the snake injects so much of it.
Q 03The female king cobra is the only snake in the world known to do what for her eggs?
Build a nest
She will build a nest by pushing dead leaves into a mound with her body, then lay her clutch inside and guard it fiercely until hatching time.
Q 04The king cobra's unusually low-pitched hiss is most often compared to which other animal sound?
A dog's growl
A dog's growl is the usual comparison, because the hiss sits at far lower frequencies than the hisses of most snakes, closer to a human voice.
Q 05On which continent do all wild king cobras live, from mangrove swamps to mountain rainforests?
Asia
Asia is the king cobra's only home, though many people picture cobras in Egypt: Africa's cobras are different snakes in a separate genus.
Q 06How does the venom of a newly hatched king cobra compare with the venom of a full-grown adult?
Just as potent
Just as potent as an adult's, a hatchling's venom makes even a baby under two feet long dangerous, and the young are notably jumpy and quick to strike.
Q 07Which country, home to the Western Ghats rainforests, is widely said to have the king cobra as its national reptile?
India
India is widely said to count the king cobra as its national reptile, and its wildlife law protects the snake, so killing one can mean prison.
Q 08Which quick mammal is the biggest natural enemy of cobras, able to bite a snake's neck before a strike lands?
Mongoose
The mongoose shrugs off much of a cobra's venom as well as dodging it: mutated nerve receptors stop the main toxin from binding.
Q 09A threatened king cobra spreads its famous hood by flattening which part of its skeleton?
Ribs
Ribs in the neck flare outward to form the hood, a warning display the king cobra pairs with a deep hiss and a raised body.
Q 10Which world record among venomous snakes belongs to the king cobra, which can rear up to an adult's eye level?
Longest
Longest is the king cobra's title: adults often reach 3 to 4 metres, and record animals have passed 5.5 metres, about 18 feet.
Q 11King cobra venom kills chiefly by shutting down breathing, an attack on which part of the body?
The nervous system
The nervous system is the target: neurotoxins block the signals that work the breathing muscles, so an untreated bite can kill a person in as little as 30 minutes.
Q 12In 2010 the IUCN Red List put the king cobra, hunted for skin and meat, in which category?
Vulnerable
Vulnerable means the species faces a high risk of extinction in the wild; the king cobra is also listed by CITES, which regulates international trade in it.
Q 13Snake charmers sometimes perform with king cobras, which respond to what rather than to the tune being played?
The swaying flute
Q 21Why are a king cobra's fangs only about half an inch long, shorter than a typical viper's?
They are fixed in place
They are fixed in place on the upper jaw and cannot fold flat like a viper's, so longer fangs would pierce the floor of the snake's own mouth.
Q 22Some genetic studies place the king cobra closer to which fast African snakes than to true cobras?
Mambas
Mambas came out as the king cobra's closest relatives in some DNA studies, though later work is less sure; either way it sits outside the true cobras in a genus of its own, Ophiophagus.
Q 23Older books call the king cobra by which name, borrowed from a nymph of Greek mythology?
Hamadryad
The swaying flute, not its music, holds the snake's attention: a cobra lacks outer ears and tracks the moving instrument as a possible threat.
Q 14How do rival male king cobras settle a contest over a female in the breeding season?
By wrestling
By wrestling, in a ritual contest that the first male to push his rival's head to the ground wins.
Q 15Which of a king cobra's senses is unusually sharp for a snake, working at ranges of about 100 metres?
Eyesight
Eyesight good enough to pick out a moving person about 330 feet off sets the king cobra apart, and it will rear up simply to see over tall grass.
Q 16At what time does a king cobra usually hunt, tracking prey by scent with its forked tongue?
During the day
During the day is when it hunts, which is why biologists call the species diurnal; sightings of one feeding at night are rare.
Q 17What lets a king cobra go for many months without eating after it has swallowed a large meal?
Slow metabolism
Slow metabolism means one big meal can fuel a king cobra for months, helped by flexible jaws that let it swallow prey much larger than its head.
Q 18With a third of its body raised and its hood spread, a king cobra can still do what?
Move forward
Move forward is what makes a rearing king cobra so unnerving: it can advance on an intruder while standing tall, so people misjudge the safe distance.
Q 19Despite a fearsome reputation, how does a wild king cobra usually react when a person disturbs it?
It slinks off
It slinks off when it can, since the king cobra prefers escape to a fight; the exception is a female guarding her eggs, who may attack unprovoked.
Q 20What is the foremost threat to wild king cobras, ahead of poaching for skins, meat and medicine?
Habitat destruction
Habitat destruction comes first, as logging and new farmland clear the forests king cobras need; the snakes are also taken for leather, bushmeat and folk remedies.
Hamadryad is the name used in older literature, and the snake was first classified as Hamadryas hannah until that genus turned out to belong to a butterfly.
Q 24A king cobra's flicking tongue carries scent particles to which sensory structure in the roof of its mouth?
Jacobson's organ
Jacobson's organ analyses the particles the forked tongue collects, which is how a king cobra can follow the odour trail of prey it cannot see.
Q 25The king cobra is an apex predator that dominates every snake in its range except which large constrictors?
Pythons
Pythons of large size are the lone exception, and a king cobra occasionally borrows their method, squeezing prey with its muscular body.
Q 26Which kitchen spice is blended with herbs in a Thai folk remedy for king cobra bites, despite no clinical proof?
Turmeric
Turmeric mixed with other herbs is the traditional treatment, but it is antivenom, given quickly, that saves a badly bitten person.
Q 27Members of Myanmar's Pakokku clan mix cobra venom into what, hoping to gain protection from snakebite?
Tattoo ink
Tattoo ink laced with venom is applied to the upper body in a weekly ritual, although no scientific evidence shows that it protects anyone.
Q 28In a traditional ritual in Myanmar, how does the priestess who handles a king cobra end her performance?
She kisses the snake
She kisses the snake on the top of its head, the finale of a rite in a country where the king cobra looms large in folklore.
Q 29According to a folk myth, a dying king cobra keeps an image of its killer in which part of its body?
Its eyes
Its eyes are said to hold the picture so that the snake's mate can track the killer down for revenge, which is why a dead cobra's head is sometimes crushed or burned.
Q 30King cobra females have been shown able to produce young with no male involved, through which process?
Parthenogenesis
Parthenogenesis, sometimes called virgin birth, was confirmed in the king cobra by a genome study published in 2021.
