Q 01Which bird has the greatest wingspan of any living species?
Wandering albatross
The wandering albatross has the largest wingspan of any living bird, averaging about 3 metres; it rides the ocean winds for hours without a single wingbeat, crossing vast distances on very little energy.
Q 02Which animal's stripes are thought mainly to deter biting flies rather than provide camouflage?
Zebra
Zebra stripes are unique to each animal, and why they exist is still argued over; experiments with striped coats on horses point to confusing biting flies rather than camouflage.
Q 03The Komodo dragon, the world's largest lizard, is native to a handful of islands in which country?
Indonesia
Indonesia is the Komodo dragon's only wild home, on Komodo, Rinca, Flores and a few nearby islets; females kept apart from males in zoos have laid eggs that hatched without any mating.
Q 04Which of these animals is an insect rather than an arachnid?
Flea
The flea is an insect, with six legs in three pairs; ticks, scorpions and tarantulas are eight-legged arachnids, though a tick hatches with only six legs and gains the last pair after its first blood meal.
Q 05Which ocean creature has three hearts?
Octopus
An octopus has three hearts: two pump blood through the gills and one drives it round the body; the main heart stops when it swims, one reason it prefers to crawl.
Q 06What is a group of lions called?
Pride
A group of lions is a pride, built around related females and their cubs, with one or a few adult males who must fight to keep their place.
Q 07Which bird is rated the fastest animal on Earth when diving?
Peregrine falcon
The peregrine falcon's hunting dive, or stoop, is credited with more than 320 km/h; it strikes prey in mid-air with a clenched foot, then turns to catch it as it falls.
Q 08What is the only mammal capable of true sustained flight?
Bat
Bats are the only mammals with powered flight; flying squirrels, colugos and sugar gliders only glide. A bat's wing is a hand, skin stretched over long finger bones, so it can flex and reshape it in mid-air.
Q 09Which animal produces the loudest sound of any living creature?
Sperm Whale
The sperm whale's clicks reach about 236 decibels underwater, the loudest sound measured from any animal; it uses them as sonar to find prey on dives into total darkness.
Q 10What distinguishes amphibians from reptiles in their life cycle?
Metamorphosis from gilled larvae
Amphibians undergo metamorphosis from gilled larvae: a tadpole breathes with gills before growing lungs and legs, while a reptile hatches as a miniature adult and never makes that switch.
Q 11Which egg-laying mammal delivers a painful venom through a spur on the male's hind foot?
Platypus
The male platypus carries a venomous spur on each hind foot; the venom is not lethal to humans but causes pain that can last weeks, and is thought to be used against rival males in the breeding season.
Q 12Which filter-feeding giant, reliably measured at 18.8 metres, is the largest fish alive?
Whale shark
The whale shark is the largest living fish, with one individual reliably measured at 18.8 metres; despite its bulk it strains plankton through its gills and is harmless to the snorkellers who swim with it off Mexico and the Philippines.
Q 13Which flightless bird lays an egg that can weigh a fifth of the mother's body weight?
Kiwi
Q 21How do dolphins sleep without drowning?
One brain hemisphere sleeps at a time
One brain hemisphere sleeps at a time in a dolphin, and the eye opposite the resting half closes while the other keeps watch, so the animal goes on surfacing to breathe and looking out for predators.
Q 22Which animal can regenerate its entire body from a tiny fragment?
Planarian flatworm
A planarian flatworm can regrow whole from a sliver as small as 1/279th of its body, head and brain included, because adult stem cells called neoblasts are spread all through it.
Q 23What is the fastest land animal over short distances?
Cheetah
The kiwi is about the size of a chicken, yet its egg fills 15 to 20 per cent of the female's body; while it grows she has to eat three times her usual amount of food.
Q 14Which of India's 'Big Four' venomous snakes warns enemies with a rasping sizzle made by rubbing its coils together?
Saw-scaled viper
The saw-scaled viper is named for the serrated ridges on its side scales; looped into coils, it rubs them together to sizzle like water on a hot plate. With the cobra, krait and Russell's viper it makes up India's 'Big Four'.
Q 15Flamingos get their pink colour from carotenoid pigments in which food?
Brine shrimp
Flamingos get their carotenoids from brine shrimp and the algae those shrimp eat, filtered from the water with upside-down bills; chicks hatch grey and turn pink only as the pigments build up.
Q 16Which mammal has the longest pregnancy, carrying its calf for about 22 months?
African elephant
The African elephant's gestation lasts around 22 months, the longest of any mammal; the newborn can stand and walk within the hour, and its mother usually waits about four years before her next calf.
Q 17What startling defence does the Texas horned lizard use against coyotes and dogs?
Squirts blood from its eyes
The Texas horned lizard squirts blood from its eyes: it raises the pressure in its head until tiny vessels around the eyelids burst, firing a jet that tastes foul to dogs, coyotes and wolves.
Q 18Which ant farms an edible fungus in vast underground gardens?
Leafcutter
Leafcutter ants don't eat the leaves they carry home: they chew them up to feed a fungus garden, and the fungus feeds the colony's young.
Q 19Chironex fleckeri, whose sting can kill a swimmer within minutes off northern Australia, is what kind of animal?
Box jellyfish
Chironex fleckeri is a box jellyfish, the most venomous jellyfish known; unlike its drifting cousins it has clusters of true eyes with lenses and swims with purpose, steering around obstacles.
Q 20Adélie penguins build their rough nests out of what material?
Stones
Adélie penguins build nests of small stones; good ones are scarce on the bare Antarctic shore, so neighbours steal from each other whenever a back is turned.
The cheetah reaches around 100 km/h in bursts of a few hundred metres, thanks to a long, flexible spine that stretches its stride and blunt claws that stay out and grip like running spikes.
Q 24Along with the common chimpanzee, which primate is our closest living relative?
Bonobo
The bonobo and the chimpanzee are the two Pan species; they split from each other only after their shared line had split from ours, so neither is any closer to us than the other.
Q 25Lemurs evolved in isolation on Madagascar, an island lying off the coast of which continent?
Africa
Madagascar lies off the southeast coast of Africa; cut off there and shaped by its sharply seasonal climate, lemurs evolved into about a hundred species, from the mouse lemur to the indri.
Q 26Which deep-sea creature has the largest eyes in the animal kingdom?
Colossal Squid
The colossal squid has the largest eyes of any living animal, about 27 cm across, the size of a dinner plate; they seem built to catch the faint glow stirred up by a hunting whale in time to flee.
Q 27Able to sprint at about 70 km/h, which is the fastest bird on land?
Ostrich
The ostrich sprints at about 70 km/h, the fastest of any bird on land; it is also the heaviest living bird and lays the largest egg of any living land animal, though relative to body size that egg is small.
Q 28Which tiny insect-eater, at about two grams, is usually ranked the world's lightest mammal?
Etruscan Shrew
The Etruscan shrew, at around 2 grams, is usually ranked the lightest of all mammals; the bumblebee bat of Thailand weighs about the same but is shorter, so the two share the 'smallest' title.
Q 29Which bird migrates the longest distance annually?
Arctic Tern
The Arctic tern flies from the Arctic to the Antarctic and back each year, a round trip tracked at 70,000 to 90,000 km and the longest known migration; its reward is two summers and more daylight than any other creature.
Q 30What adaptation allows the wood frog to survive being frozen solid?
Glucose floods its tissues
Glucose floods its tissues from the liver as the first ice forms, a sugary antifreeze that stops the wood frog's cells freezing inside; its heart and breathing then stop until the thaw.
