It ranges across mammals, birds, reptiles, fish, insects and the deep sea, from easy warm-ups about the fastest and biggest animals to genuinely hard questions about animal behaviour, record holders and the odd ways nature solves problems.

Q 02Which bird is known for its ability to mimic human speech?
African grey
The African grey's gift for talking made it a pet-trade favourite: nearly 360,000 wild-caught birds were exported between 1994 and 2003.
Q 03In which animal does the male carry the eggs in a pouch and give birth to the young?
Seahorse
The male seahorse's brood pouch can hold over a thousand eggs, and when the young are ready he gives birth with powerful muscular contractions.
Q 04Which mammal is known for having the longest gestation period?
African elephant
The African elephant carries its calf for about 22 months, and other females in the herd then help raise it, a shared care called allomothering.
Q 05What is a group of wolves called?
Pack
A group of wolves is a pack, typically a breeding pair and their offspring from the last few years; packs cooperate to bring down prey as large as moose.
Q 06Which ocean creature has three hearts?
Octopus
Octopuses have three hearts, and their blood is blue because it carries oxygen with copper-based haemocyanin rather than iron.
Q 07What is the fastest land animal?
Cheetah
The cheetah is built for sprinting, not fighting, so lions and hyenas routinely steal the prey it has just caught.
Q 08Which animal produces the loudest sound in the animal kingdom?
Sperm whale
The sperm whale's clicks are focused by the waxy spermaceti in its head, which early whalers mistook for sperm, giving the whale its name.
Q 09What is the primary diet of a koala?
Eucalyptus leaves
Koalas eat almost only eucalyptus leaves, which are toxic to most mammals; a young koala first eats pap, a soft dropping from its mother thought to supply the gut bacteria to digest them.
Q 10Which is the only penguin species found north of the equator?
Galápagos
The Galápagos penguin can live at the equator because cold, nutrient-rich currents such as the Cromwell Current cool the water and bring it food.
Q 11What is the name for a baby kangaroo?
Joey
A newborn joey is only a few centimetres long, yet it crawls through its mother's fur and into her pouch on its own.
Q 12Adult salmon find the exact stream where they hatched mainly by using which sense?
Smell
Smell: a young salmon imprints on its home stream's scent before heading out to sea, and as an adult it follows that odour back to spawn.
Q 13Along with the bonobo, which primate is one of humankind's two closest living relatives?
Chimpanzee
In 1960 Jane Goodall watched a chimpanzee shape a twig to fish termites from a mound, a find that forced scientists to rethink what makes humans unique.
Q 21Which bird feeds with its head held upside down in the water?
Flamingo
The flamingo's bill works upside down: comb-like plates called lamellae along its edges filter food from the water as the bird pumps it through.
Q 22What is the largest species of penguin?
Emperor
The emperor penguin is the largest penguin; the male balances the egg on his feet through the Antarctic winter, fasting for months until it hatches.
Q 23Sharks sense hidden prey through the ampullae of Lorenzini, organs of which sense?
Electroreception
Electroreception lets sharks feel the weak electric fields other animals' muscles make; great hammerheads sweep their heads over the seabed to find stingrays buried in sand.
Q 14What is the largest species of bear?
Polar bear
The polar bear is the largest bear species, and it isn't really white: its skin is black and its hairs are clear, looking white only because they scatter light.
Q 15What is the only mammal capable of true sustained flight?
Bat
Bats are the only mammals capable of true flight, and vampire bats even regurgitate blood to feed their roost-mates.
Q 16What is the largest animal known to have ever existed?
Blue whale
The blue whale, the largest animal known, lives almost entirely on krill, tiny crustaceans, and eats several tonnes of them a day.
Q 17What is the largest living fish in the world?
Whale shark
The whale shark is the largest living fish, growing up to 40 feet or more in length. Despite their enormous size, whale sharks are filter feeders that eat plankton, fish eggs, and small fish.
Q 18Which Australian marsupial produces cube-shaped droppings, which it uses to mark its territory?
Wombat
The wombat's intestine has stiff and stretchy sections that shape its droppings into cubes, which are thought to roll away less when it marks its territory.
Q 19Where are a cricket's ears located?
On their front legs
Crickets hear through eardrums on their front legs, and a parasitic fly, Ormia ochracea, homes in on a male's song to drop its larvae on him.
Q 20Which seabird's yearly round trip from the far north to waters around the South Pole is the longest migration known?
Arctic tern
The Arctic tern breeds in the Arctic summer and then flies to Antarctica for a second summer, so it sees more daylight than any other animal.
Q 24Which animal can rotate its head almost 270 degrees?
Owl
Owls' eyes are fixed in their sockets and can't swivel, so an owl turns its whole head to look around instead.
Q 25Which species of whale is known for its complex, haunting songs?
Humpback
Humpback males sing complex songs in the breeding season, and all the whales in an area sing virtually the same song, which slowly changes over time.
Q 26What structure do birds have instead of teeth for grinding food?
Gizzard
Birds grind their food in the gizzard, a muscular stomach, and many swallow gravel that does the work teeth would do.
Q 27Which endangered great ape is found only on the islands of Borneo and Sumatra?
Orangutan
The orangutan's name is Malay for 'person of the forest', and it builds a fresh nest of branches in the trees every day to sleep in.
Q 28What is the hard outer covering of insects called?

Insects have an exoskeleton of tough chitin, and because it cannot grow with them, they must moult it and form a new one to get bigger.
Q 29What is the primary reason flamingos are pink?
Pigments from their diet
Pigments from their diet: carotenoids in the algae and small crustaceans flamingos eat colour their feathers, and captive birds fed without them fade to pale pink.
Q 30Which Australian bird incubates its eggs in a large mound of rotting leaf litter?
Malleefowl
The malleefowl lays its eggs in a big compost mound, and the male adds or removes material to regulate the heat while they develop.
