96 free Wildlife trivia questions with answers — nature quiz, new questions added Aug 2026.
Fifty free wild animal trivia questions with answers, from the savanna to the deep sea. The easy openers ask about the fastest land animal, the tallest, the largest bear and the only mammal that truly flies; the middle of the set gets into how dolphins sleep, why polar bear skin is black and which shark has to keep swimming; the hard end wants the loudest whale, the only primate with a toxic bite and the bison that was brought back from 48 zoo animals. It is a wildlife quiz rather than a pets-and-farm one, so expect Arctic terns, leafcutter ants, wildebeest, slow lorises, pistol shrimp and the IUCN Red List. Conservation gets its own thread: shark finning, the northern white rhino, monarch butterflies and the wolves that changed Yellowstone's rivers. Every answer is checked against a reference source, so the numbers and superlatives hold up when someone in the room says "actually".

Q 01What is the fastest land animal in the world?
Cheetah
Cheetah sprints top out around 60 to 65 mph in short bursts; powerful hindlimbs, long legs and a flexible spine are all built for speed.
Q 02Which animal is the tallest living land animal?
Giraffe
Giraffe bulls can browse leaves well above the reach of any other land mammal, and they chew the cud like a cow.
Q 03What is a group of wolves called?
Pack
Pack life is cooperative: a breeding pair and their offspring hunt together, and the weak are supported by the efforts of stronger wolves.
Q 04Roughly how many words did the budgerigar Puck know, per his 1995 Guinness record for largest bird vocabulary?
1,728
Puck, a budgerigar owned by Camille Jordan of Petaluma, California, knew 1,728 words, and the 1995 Guinness Book of Records listed him as the bird with the largest vocabulary.
Q 05What is the largest species of bear?
Polar bear
Polar bear is the largest bear species: adult males typically weigh 400 to 700 kg, and the heaviest wild male on record, shot at Kotzebue Sound, Alaska in 1960, weighed about 1,002 kg.
Q 06How many legs does a butterfly have?
6
6, like all insects, though brush-footed butterflies tuck their front pair away so small that they seem to have only four.
Q 07Which ocean animal is known for having three hearts?
Octopus
Octopuses have three hearts: two branchial hearts pump blood through the gills, and one systemic heart pumps blood through the rest of the body. The systemic heart actually stops beating when the octopus swims.
Q 08How many species of flamingo exist worldwide?
6
Four species live in the Americas, including the Caribbean, and two are native to Afro-Eurasia; all of them usually rest standing on one leg.
Q 09Which Australian marsupial is known for sleeping up to 20 hours a day?
Koala
Koalas are sedentary because their eucalyptus diet is so low in energy; food can sit in the hindgut for 100 hours in the wild.
Q 10What is the national animal of the United States?
Bald eagle
Bald eagle has been the national emblem since the Great Seal was adopted in 1782, and Congress formally named it the national bird in December 2024; the American bison is the national mammal.
Q 11Which reptile has the strongest bite force ever measured?
Saltwater crocodile
The saltwater crocodile has the strongest bite force ever measured at approximately 3,700 PSI (pounds per square inch). Despite this crushing power, the muscles that open their jaws are relatively weak.
Q 12What is the primary reason coral reefs are sometimes called the "rainforests of the sea"?
They support enormous biodiversity
They support enormous biodiversity: an estimated 25% of all marine species on less than 1% of the ocean floor.
Q 13Which lizard is the largest living species and carries venom glands in its lower jaw?
Komodo dragon
Q 21Which sea turtle species is the largest?
Leatherback
Leatherback is the largest sea turtle, commonly 1.8 to 2.2 m long and up to 500 kg or more, and unlike the others it has a flexible, leathery carapace instead of a hard shell.
Q 22What adaptation allows owls to fly almost silently?
Specialized feather edges
Specialized feather edges do it: comb-like serrations on the leading edge, a soft fringe on the trailing edge and a velvety surface that break up turbulence.
Q 23Which organization publishes the Red List of Threatened Species?
IUCN
The IUCN Red List is the world's most comprehensive inventory of the conservation status of species. Established in 1964, it evaluates the extinction risk of thousands of species using criteria including population size, rate of decline, and geographic range.
Komodo dragons reach 10 feet, the largest living lizard, and venom glands in the lower jaw help bring down prey.
Q 14How do dolphins sleep without drowning?
They shut down half their brain at a time
They shut down half their brain at a time, so one hemisphere rests while the other keeps them surfacing to breathe and watching for predators.
Q 15Which species of shark must keep swimming to breathe?
Great white
Great white sharks are obligate ram ventilators, meaning they must keep swimming forward with their mouths open to force water over their gills. If they stop swimming, they cannot breathe. Some other sharks, like nurse sharks, can pump water over their gills while stationary.
Q 16What is the annual circular wildebeest movement through the Serengeti and Masai Mara called?
The Great Migration
The Great Migration moves around 1.5 million wildebeest, plus zebras and gazelles, in a loop between Tanzania and Kenya following the rains.
Q 17Roughly what share of the world's bee species are solitary rather than colony-living?
Over 90%
Over 90% of the world's roughly 20,000 bee species are solitary: mason, leafcutter and most carpenter bees nest alone, while honey bees, bumblebees and stingless bees are the social minority.
Q 18What is the purpose of a chameleon changing its color?
Signalling and temperature
While commonly believed to be for camouflage, chameleons primarily change color to communicate with other chameleons (displaying mood, dominance, or mating readiness) and to regulate body temperature by absorbing or reflecting light.
Q 19Bonobos live in the wild in only one country — which?
Democratic Republic of the Congo
Democratic Republic of the Congo is the only country with wild bonobos; they live in humid forests south of the Congo River, which separates them from chimpanzees to the north.
Q 20What is the term for an animal that hunts and eats other animals?
Predator
Predator and prey shape each other: the hunt keeps population sizes in check and drives the adaptations on both sides.
Q 24What is the only mammal capable of true powered flight?
Bat
Bats alone among mammals generate lift with their wing membranes; flying squirrels, sugar gliders and colugos can only glide.
Q 25What color is a polar bear's skin underneath its white fur?
Black
Black skin absorbs heat from the sun; the fur only looks white because its transparent hairs scatter visible light, much as snow does.
Q 26Which eagle was officially called the monkey-eating eagle until 1978?
Philippine eagle
Philippine eagle (Pithecophaga jefferyi) was renamed from monkey-eating eagle by a 1978 presidential proclamation; it is the Philippines' national bird and critically endangered, with a wingspan of about two metres.
Q 27What is the phenomenon where a non-venomous species evolves to look like a venomous one?
Batesian mimicry
Batesian mimicry is when a harmless species evolves to imitate the warning signals of a harmful species to deter predators. For example, the non-venomous scarlet kingsnake mimics the color pattern of the venomous coral snake.
Q 28What percentage of all known animal species are invertebrates?
About 97%
Approximately 97% of all known animal species are invertebrates — animals without a backbone. This includes insects, arachnids, mollusks, crustaceans, worms, and many more. Vertebrates (mammals, birds, reptiles, amphibians, fish) make up only about 3%.
Q 29Who narrated the BBC's 2006 series 'Planet Earth'?
David Attenborough
David Attenborough returned to narrate Planet Earth II a decade later, by then aged 90.
Q 30What word sums up the variety of life in an ecosystem?
Biodiversity
Biodiversity is the variety of life at three levels: genetic diversity within a species, species diversity within a habitat, and ecosystem diversity across a region.
