48 free Komodo Dragon trivia questions with answers — nature quiz, new questions added Sep 2026.
The Komodo dragon is the biggest lizard on Earth, and it has the stories to match. This quiz covers where the dragons actually live, how big the largest verified specimens really were, how they hunt deer and buffalo, why the old "deadly bacteria" theory was overturned by the discovery of venom glands, and how a female at Chester Zoo produced a clutch of sons without ever meeting a male. It also digs into the human side: the 1910 rumours of a "land crocodile" that reached the Dutch colonial administration, the 1926 expedition that inspired King Kong, London Zoo's first dragons in 1927, the villagers who moved their graves to stop the lizards digging them up, and the newspaper editor bitten on the foot at Los Angeles Zoo. Easy questions ask which country and which lizard family; the hard ones want ear-bone counts, tooth-replacement rates and the number of eggs Flora laid. Every answer was checked against Wikipedia's articles on the Komodo dragon and Komodo National Park, and each question carries the sentence that supports it. If you enjoy this one, our Lizards and Reptiles quizzes go wider.

Q 01Which broadcaster first showed British viewers a Komodo dragon, in the early BBC series Zoo Quest for a Dragon?
David Attenborough
David Attenborough's dragon footage went out in black and white, yet it had been shot on colour film, which lay forgotten in the BBC's vaults until 2015.
Q 02Komodo dragons are native to islands in which country?
Indonesia
Indonesia: though it is the biggest lizard on Earth, the dragon went unnoticed by Western science until the twentieth century.
Q 03The Komodo dragon belongs to which lizard family?
Varanidae (monitor lizards)
Monitors are the family that also includes Australia's perentie and lace monitor and Africa's Nile monitor.
Q 04A fully grown Komodo dragon reaches roughly what length?
3 m (10 ft)
3 m (10 ft): at that size an adult has nothing to fear on its islands, where it sits at the top of the food chain with no predator of its own.
Q 05What is the main prey of adult Komodo dragons in the wild?
Javan rusa deer and feral pigs
Javan rusa deer and feral pigs top the menu: a dragon lies in wait beside a game trail, then lunges at whatever walks past.
Q 06Why do young Komodo dragons spend their early years up in trees?
To stay clear of cannibal adults
To stay clear of cannibal adults: grown dragons readily eat smaller ones but are too heavy to climb, so hatchlings head straight up the nearest trunk.
Q 07Young Komodo dragons give themselves an off-putting smell by rolling in what?
Faeces
Faeces: bigger dragons steer clear of the stink, so a well-rolled youngster is left alone.
Q 08After science described the Komodo dragon, Dutch officials did what?
Protected it
Protected it: officials realised how few dragons existed, so sport hunting was banned and collecting for science tightly limited.
Q 09In 2021 the IUCN Red List moved the Komodo dragon to which category?
Endangered
Endangered: it had been listed as Vulnerable, but rising seas are expected to swallow a large share of its low-lying island habitat.
Q 10Komodo National Park holds which status?
World Heritage Site
World Heritage Site: the UNESCO listing covers more than the lizards, taking in coral reefs, dugongs, whales and sea turtles in the waters around the islands.
Q 11Islanders' old name for the Komodo dragon, 'buaya darat', translates as what?
A 'land crocodile'
A 'land crocodile': buaya is Malay for crocodile and darat means land, a fair description of a three-metre reptile that hunts ashore.
Q 12After digesting a kill, a Komodo dragon coughs up a slimy pellet of horns, hair and teeth, much like which bird?
An owl
An owl: neither animal can break down hair, horn or teeth, so the leftovers come back up as a foul pellet, which the dragon wipes off its face in the dirt.
Q 13Joan Procter, a pioneering reptile curator of the 1920s, handled and studied live Komodo dragons at which zoo?
London Zoo
Q 21What colour is a Komodo dragon's forked tongue?
Yellow
Yellow: just under that tongue sits the opening of a breathing tube, so a dragon can keep taking in air with its mouth crammed full of food.
Q 22A Komodo dragon's skin is reinforced by tiny bones called what?
Osteoderms
Osteoderms: scans show the bony beads link up like chain mail in adults, while babies have none, which suggests the armour is for fights with other dragons.
Q 23A 2024 study found Komodo dragon tooth serrations are coated with what?
Iron
Iron: an orange, iron-rich layer along the serrations protects the thin enamel beneath, so the blades stay sharp enough to slice through flesh.
London Zoo: Procter designed its Reptile House, and in 1928 she brought a living dragon before a meeting of the Zoological Society.
Q 14A 1926 expedition to Komodo Island that returned with preserved and live specimens inspired which 1933 film?
King Kong
King Kong: producer Merian C. Cooper read his friend Douglas Burden's account of hunting the dragons and imagined a giant gorilla battling lizards like them.
Q 15How do rival Komodo dragons fight over mates in the breeding season?
Wrestling upright on their hind legs
Wrestling upright on their hind legs: propped on their tails, the rivals grapple chest to chest until one is thrown to the ground.
Q 16Where does an adult Komodo dragon usually spend the night?
In a burrow it has dug
In a burrow it has dug: the snug hole holds body heat overnight, so the cold-blooded giant needs less basking before the morning hunt.
Q 17How much of a big carcass does a Komodo dragon usually eat?
Nearly all of it, bones included
Nearly all of it, bones included: a dragon bolts down hide and hoof alike, leaving scavengers little more than scraps.
Q 18Beyond the national park, wild Komodo dragons survive on which larger island, also known for its 'hobbit' fossils?
Flores
Flores: dragons cling on along its western and northern coasts, where they lack the park's protection and human activity keeps eating into their habitat.
Q 19Fossils show the Komodo dragon once lived where, alongside the giant lizard megalania?
Australia
Australia: Queensland fossils match the living dragon, so it seems to have grown huge on the mainland and spread west, not ballooned on small islands as once thought.
Q 20A Komodo dragon's short, serrated teeth are often likened to those of which predator?
A shark
A shark: the teeth are flat, curved blades with saw edges, built to slice through flesh as the dragon bites down and pulls back, not to grip and hold.
Q 24What happens when a Komodo dragon loses a tooth?
A spare replaces it
A spare replaces it: replacements queue up behind every tooth, and a dragon gets through several full sets of teeth in a lifetime.
Q 25How does a Komodo dragon pick up the scent of a distant carcass?
Flicking its tongue in the air
Flicking its tongue in the air: the forked tips carry scent molecules to sense organs in the roof of the mouth, so the dragon in effect smells by tasting.
Q 26Why does a Komodo dragon ambush prey instead of chasing it down?
It sprints only briefly
It sprints only briefly: the charge is fast but short, so a dragon hides beside a trail for hours and strikes at close range.
Q 27Up to what proportion of its own body mass can a Komodo dragon eat in a single meal?
80%
80%: jaws that gape unusually wide and a stomach that stretches like a sack let an adult gorge on most of its own weight in one sitting.
Q 28A large Komodo dragon can get by on roughly how many big meals?
One a month
One a month: a cold-blooded body burns so little fuel that a single carcass can keep a big dragon going for weeks.
Q 29What is the largest prey a Komodo dragon will take on?
A water buffalo
A water buffalo: far too big to kill outright, it usually escapes the first attack, so the dragon simply trails the wounded animal until it weakens.
Q 30During the Pleistocene, Komodo dragons are thought to have preyed mainly on dwarf species of what?
Stegodon, an elephant relative
Stegodon, an elephant relative: island life shrank these tuskers to pygmy size, and they were the only big game around until people shipped in the animals dragons hunt today.
