How a lizard can literally walk on water; how hippos speed through water if they can't actually swim; how bees find nectar; jellyfish; cats' whiskers.

How owls catch prey they can't see; a theory about the proximity of rats; what makes octopuses masters of disguise; why penguins' feet don't freeze; why African wild dogs are the ultimate hunters.

How hummingbirds fly backwards; an investigation into whether cockroaches will survive the apocalypse; how dogs know when people are sad; the hagfish.

What a dog's tail wag means; the cleverness of cockatoos; zebras' black and white stripes; the secret behind a crocodile's powerful jaws; how chameleons change color.

How cats detect earthquakes; how owls hunt in total darkness; how cheetahs accelerate more quickly than a car; how sea otters keep warm in icy waters; how ants heal their wounded.

How the blue whale became the biggest animal ever; why elephants have trunks; why ladybugs have spots; why some animals live a long time; why cats purr.

The intelligence of dolphins; how hyenas eat every last scrap of their dinner; how geckos defy gravity; how leeches suck blood; why some cats are afraid of water and others love it.

How squirrels find their nuts; how bees make honey; why some cobras spit; whether alligators are music lovers; whether a bug can survive in space.

A look at why dogs tilt their heads, how massive humpback whales propel themselves into the air, do hippos sweat blood, why animals swarm, and why spiders jump out of their skin.

A look at how woodpeckers avoid concussions, why giraffes' tongues are black, how ants can survive a flood, and how octopuses squeeze into tiny spaces.

A look at how anteaters slurp up so many ants, why beavers build dams, how canines stay cool, why humpback whales sing, and why dung beetles do what they do.

A look at how dogs detect underwater targets, what makes ostriches nature's best marathon runners, how sloths spend so much time upside down without passing out, and can a pelican bill really hold more than his belly can.
