1. Amphibians
   Mammals
2. Poisonous
   Winged

Frogs make up the vast majority of the taxonomic class "Amphibia." These are animals that are equally well-adapted to water and land, or split their time between these environments. The other three things aren't well known (we hope!) because they aren't actually true.

1. Golden or yellow
   Green, often shading toward brown
2. White to pale gray
   Dark brown or black

Ask a child to draw a frog, and he or she will very likely reach for the green crayon. The same is probably true of an adult with a paint palette, to be honest. But frogs do range in color, with gold and black and red all represented. Sometimes they're virtually colorblocked, as if designed by Tommy Hilfiger.

1. Anura
   Artiodactlya
2. Lepidora
   Cervidae

The lineage goes like this: Animalia-Chordata-Amphibia-Anura. From there, frogs fall into different families. The order name "Anura" comes from the Greek language, and means "without tail."

1. Toads are frogs that are brownish in color.
   Toads are not in the order Anura at all
2. Toads are ovoviviparous frogs (keeping eggs inside the body)
   Uhhhh ...

Toads are all within the order Anura, but there is no solid definition of what makes a frog a toad. Some purists will tell you that only members of the family Bufonidae are "real toads," and this might be as good a definition as any.

1. Live births
   Having dry skin
2. Living on land
   Warts

Toads, like all frogs, lay eggs. It is also common for them to have dry skin and warts. The warts aren't a sign of an underlying medical issue, as they often are in other animals. They are characteristic of the toad, and they do NOT transmit them to humans.

1. A triceratops-like "frill"
   Horns
2. A prehensile mind
   Venomous "spurs" on their feet

The United States is home to more than half of the world's horned toad species, including the Texas Horned Lizard. Fun fact: Horned frogs are known for their fearlessness and voracious appetite, sometimes trying to consume an animal as large as themselves.

If you were expecting this to be strictly a scientific quiz ... well, we're sorry to disappoint you! You'll find several questions on frogs in art and popular culture in this quiz. Evidently, they've fascinated humans for some time!

1. Carnivorous
   Frutivorous
2. Graminivorous
   Omnivorous

This characteristic, being carnivorous, makes frogs both a common predator and a common prey animal. Sidenote: We swear we're not making up the word "graminivorous." It means, "eating grasses or the seeds of grasses."

1. With their tongue
   With their front legs
2. By hopping and landing hard on them
   By creating a sticky substance the insects get trapped in

You've probably seen this in animations before — it's a favorite for artists to draw, the frog's tongue flicking out at lightning speed and catching a fly out of the air. We sometimes wish we had this skill on mornings when we're in a hurry and see a donut conveniently out on the counter!

1. Antarctica
   A large part of northern Africa
2. A large part of Saudi Arabia
   All of these

Snowy tundra and dry, hot desert are both inhospitable habitats for frogs. Otherwise, a world map of their distribution shows that these hardy creatures have a presence almost everywhere: The Americas, Australia, most of Africa and Asia, and Europe.

1. A horse
   A leprechaun
2. A prince
   A pumpkin

Every reader of fairy tales knows this one. But we have lingering questions: If you kiss a female frog, does she turn into a princess? If so, why is this never represented in fairy tales? (We suppose the original "Shrek" comes close. If you don't catch this reference, watch it again. It's worth it!)

1. A frog's egg
   A group of frogs
2. A particularly large wart on a toad
   A vestigial tail

This name, as well as the alternate, "army," is informal, not a part of scientific nomenclature. It's one of the less-inventive names for an animal group that we've heard: Our reigning favorite is "a prickle of porcupines."

1. 80,000 years ago
   250,000 years ago
2. 1 million years ago
   2 million years ago

This makes frogs not quite as old as Homo sapiens, who were believed to branch off from Homo erectus about 350,000 years ago. Frogs are real survivors, though, having made it through several mass extinction events, but many species are on the "threatened" list today.

1. Less than one-tenth
   About 15 percent
2. Approximately 40 percent
   Most of it

Tree frogs live an "arboreal" life (the adjective is derived from the Latin word for "tree"; think of Arbor Day). They are often green — sometimes bright green — in order to camouflage themselves, and have sticky toe pads to help them adhere to vertical surfaces.

1. Nest-building skills
   Hollow bones
2. Small size
   Wings

Tree frogs don't have hollow bones like birds do, but their diminutive size and light weight helps them to ascend to heights and stay there. A light weight also means that slender branches won't break underneath them.

1. It is mostly aquatic.
   It feeds on flowers.
2. It is successful at mating.
   It is toxic.

Smaller animals have several ways to signal to predators that they are not worth the risk of attacking. Bright colors, in frogs, indicate that they have toxic glands and skin secretions, and won't be a pleasant experience to eat.

1. Up in trees
   In grass
2. In sand
   In water

This makes sense, as the young are born as tadpoles. The tadpoles start their life as fully aquatic creatures, only growing limbs and venturing onto land as adult frogs. Fun fact: A group of frog eggs is called a "frogspawn."

1. Crawdad
   Goldfish
2. Hatchling
   Pollywog

Kind of a silly name, right? Not that "tadpole" is that much more dignified. Fun fact: Because tadpoles/pollywogs have no bones, there aren't any pollywog fossils ... but the remnants of tadpole "biofilms" have been found and used for study.

1. They are twice as efficient as adult frog lungs.
   They are a delicacy in Sri Lanka.
2. Tadpoles only have one lung.
   Tadpoles have no lungs.

Psych! Tadpoles are entirely aquatic, and breathe through gills, as many (though not all) aquatic creatures do. Few animals are so different in their juvenile and adult forms as tadpoles and frogs. Tadpoles have tails but no limbs, are herbivorous and breathe through gills. Frogs have legs but no tail, are mostly carnivorous and breathe air through lungs.

1. Eyes
   Knees
2. Ribs
   Toes

A frog's wide-set and bulging eyes are a vital early-warning system: They have a wide range of vision, more than 300 degrees, which makes them pretty difficult to sneak up on. News of the Weird Dept: Frogs' eyes aid them in swallowing food — they can "retract" their eyeballs to create pressure that forces food downward.

1. Dusk sleep
   Somnolence
2. Torpor
   It's just called hibernation

Kids learn about hibernation in schools. usually in relation to bears. But scientists have identified several other "hibernation-like" states, including torpor. It is marked by a low body temperature and reduced metabolic activity.

1. Its size
   It is mentioned in the Bible.
2. It is found in the Middle East.
   It's afraid of slingshots.

The Goliath of the Bible was a giant, and among frogs, so is its namesake. It can grow to more than a foot and a half long, and some have been weighed at more then seven pounds. This will probably not help anyone with a frog-and-toad phobia.

1. A grain of sand
   A pea
2. A golf ball
   A tennis ball

The tiny Paedophyrne Amauensis is so little you could fit two or three on a dime (and if you Google a photo of the little guy, you might see the frog sitting on one, for scale). It's easily mistaken for an insect because its tiny, shrill call sounds like that of a bug. Coming from so small a chest, that's not a surprise!

1. Once a day
   Less than once a day
2. Several times a day
   Frogs do not drink.

Most frogs absorb water through their skin, instead of consuming water the way mammals and some other animals do. This is why frogs can't live too far from a water source: If their skin dries out, they die of dehydration.

1. Fleas
   Ticks
2. Microbes
   All of these

While we find frogs' slimy skin unpleasant to the touch, that slime is not only keeping the frog hydrated, but hosting a rich variety of microbes. These microbes are important to health, just like the ones in a human's digestive system.

1. Vertebrae
   Toes
2. Ribs
   Teeth

Frogs have teeth? It's strange, but most do, while toads do not. It's ribs that frogs lack, a feature that most vertebrates need to allow for breathing. In place of ribs, frogs use a process called "buccal pumping" to breathe.

1. Cold-blooded
   Warm-blooded
2. Fond of salty environments
   Well-adapted to high altitudes

Ectotherms cannot regulate their body temperate from within, like mammals can, thanks to our rock-star hypothalamuses (hypothalami?). Frogs need to seek out warm environments, but avoid those that are too hot, to accomplish the same thing.

1. Pandas
   Meerkats
2. Salamanders
   None of these

The "croak" is unique to the frog. Many of them have "vocal sacs" under the mouth which fill with air and amplify the call. The main purpose of a frog's croak is to attract a mate, with females preferring a loud, low croak.

1. Four feet
   More than six feet
2. 10 feet
   10 yards

To be exact, it was seen to jump six feet, seven inches. While that might not sound terribly impressive to you, it's more than 50 times the small rocket frog's body length. Sure beats the Jack Russell terrier, which is the best jumper among dogs, but can only jump five times its height.

1. Heidi
   Peter Pan
2. Seven Brides for Seven Brothers
   The Wind in the Willows

"Mr. Toad" is a rich and snazzily-dressed toad in the children's book by Kenneth Grahame. He's also the star of a play by A.A. Milne, "Toad of Toad Hall." Who says that frogs get all the best roles?

1. Yes, it does.
2. Nope!

This odd-looking brown-and-green frog grows hair-like papillae along the centerline of its body; it looks a bit like a Hawaiian grass skirt. Need to Know Department: The "hairy frog" will also break its own toes when threatened by a predator, in order to make the toes claw-like and use them as weapons. Hardcore!

1. Catching prey
   Gliding (for flying frogs, over short distances)
2. Swimming
   Both swimming and gliding

Many frogs swim, but fewer are "flying" frogs, ones that can glide over short distances. In the latter case, the webbing spreads out and serves a parachute-like function, increasing air resistance and lift.

1. Burrowing
   Climbing
2. "Flying" (gliding, really)
   Frogs do all these things.

Frogs are a diverse lot, and do all these things. You might have heard of "flying" frogs, which can leap from heights and glide — but maybe you were surprised to learn that there are digging and burrowing frogs as well. The official term for this is "fossorial."

It's confusing, isn't it? Frogs in general don't live in the Arctic or Antarctic regions ... and yet the wood frog's territory extends into areas above the Arctic Circle, and it's well-adapted to surviving in the cold. This frog stores glucose in its internal organs, which allows it to survive with more than half its body frozen.

1. Edible frog
   Golden poison dart frog
2. Snowy Arctic frog
   Diana's bare-hearted glass frog

Yes, people really do eat the "edible frog." Especially in France, where frogs' legs are something of a national dish. But there's no snowy Arctic frog -- as noted in another question, they don't survive at the poles!
