1. elephant
   hyena
2. ocelot
   macaw

It's the spotted hyena that has this nickname. Other breeds of hyena include the striped and brown hyenas.

1. aardvark
   rhinoceros
2. rooster
   shark

Roosters, the male of the chicken species, have a rubbery-looking red "comb" atop their heads. This separates them from the females, called hens.

1. octopus
   shark
2. squid
   whale

It was Steven Spielberg, with "Jaws," who made the dorsal fin the popular -- and chilling -- sign of a shark's presence. However, they often attack from underneath without the fin breaking the surface.

1. bat
   buzzard
2. hawk
   vole

Bats are indeed mammals. Their furry, warm bodies are responsible for their German name "fledermaus" or "flying mouse."

1. chameleon
   octopus
2. parrot
   raven

Many types of chameleon can change color to match their background, thus hiding from predators. When relaxed, these lizards are usually green.

1. duck
   lynx
2. platypus
   both #1 and #3

When early naturalists were first confronted with the platypus, its duck-like bill was one of the things they found hard to believe. Some scientists thought the oddball platypus was some kind of elaborate hoax.

1. hedgehogs
   honeybees
2. moles
   prairie dogs

Honeybee colonies have a queen, male drones (for mating), and female worker bees. They provide humans with honey -- yay! -- but their sting can be life-threatening to humans with allergies.

1. cormorant
   golden eagle
2. peacock
   raven

It's the NBC logo, of course, that's shaped like a peacock. Only the males have the gorgeous feather tail -- peahens are rather plain.

1. dodo
   golden eagle
2. white rhinoceros
   eland

The dodo was a flightless bird native to Mauritius. Though it's hardly the only animal to have gone extinct, it's the one most people can name (other than the dinosaurs, who became extinct much earlier).

1. dog
   elephant
2. giraffe
   polar bear

This one isn't a myth. Elephants, which have long lives in general, really do appear to recognize each other after years of separation.

1. elephant
   Komodo dragon
2. rhinoceros
   bison

The rhinoceros is hunted for its horn, which is made of keratin, like human fingernails. Superstitions persist about rhino horns having health benefits when powdered and consumed.

1. ocelot
   puma
2. tiger
   zebra

A zebra is basically an exotically-colored horse, but much rarer. That's why doctors have a saying: "When you hear hoofbeats, think of horses, not of zebras."

1. buffalo
   deer
2. deer ticks
   ants

Only male deer, called stags, have antlers. In youth, the antlers are covered with a short-furred skin called "velvet," which weathers away in maturity.

1. house flies
   cats
2. pigeons
   cows

Though more than one bird frequents urban areas, it's the pigeon who takes most of the blame for fouling sidewalks, statues and more with its guano. Some people go so far as to call them "sky rates."

1. bear
   elephant
2. fox
   tiger

Most members of the Ursidae family hibernate. This means they go into a state of unconsciousness and slow metabolism, burning stored fat, during cold months when food is hard to find.

1. buzzard
   house cat
2. porcupine
   vole

The porcupine has an unusual defense mechanism: hairs covered with stiff keratin, called quills. Porcupines are cute, but you'd best keep your distance.

1. ostrich
   Gila monster
2. platypus
   pit viper

The platypus is one of a group called monotremes, the egg-laying mammals. When the eggs hatch, the platypus nurses its young, called "platypups" or "puggles." (Awww!)

1. chupacabra
   osprey
2. ocelot
   vampire bat

Vampire bats commonly feed on farm animals. However, since they can spread rabies, they are considered dangerous to humans.

1. pig
   mule
2. shrew
   sloth

The word "sloth" means "laziness." But the sloth isn't the top sleeper of the animal kingdom -- that's the koala, which sleeps up to 22 hours a day! The sloth weighs in at about 19 hours of sleep each day.

1. bald eagle
   blue tick hound
2. grey goose
   calico cat

In adulthood, the bald eagle has a dark body and a white head. Young bald eagles are dark all over.

1. bat
   dolphin
2. dormouse
   penguin

It's mainly the bottle-nosed dolphin that always looks like it's smiling. That, and it's friendly "chattering" noise, make it a favorite at water parks.

1. mole
   lynx
2. skunk
   Gila monster

In their defense, skunks smell OK on a day-to-day basis. It's just when they're threatened that they release that powerful, sour-smelling spray.

1. blue whale
   Komodo dragon
2. killer whale
   great white shark

The blue whale can weigh up to 40,000 pounds and measure nearly 100 feet long. Surprisingly, it doesn't eat sharks and smaller whales, but has a simple diet of krill.

1. condor
   golden eagle
2. ostrich
   stork

The ostrich, a land bird, does not fly. It is, however, quite a speedy runner.

1. chihuahua
   mastiff
2. Irish wolfhound
   FInnish lapphund

Though mastiffs are known for their size and powerful build, the Irish wolfhound is the tallest of dogs. (If you said chihuahua, go to your room, right now.)

1. cheetah
   eland
2. mule deer
   road runner

If a cheetah were a car, it would break the speed limit of many roadways! It reaches speeds of up to 70 mph.

1. crow
   kestrel
2. raven
   both #1 and #3

In romantic novels, you'll often see a black-haired character described as "raven-haired." "Crow-haired" would be equally accurate, but for some reason, it never caught on.

1. antelope
   mastiff
2. moose
   buzzard

Just witness "Moose Mason" of the Archie Comics world -- he's the jock who struggles with his schoolwork.

1. albatross
   eagle
2. ostrich
   turkey vulture

The wandering albatross has a wingspan of nearly 12 feet across. They can glide for hours -- yes, hours -- at a time, enabled by this virtual parasail.

1. ferret
   hummingbird
2. housecat
   chihuahua

Hummingbirds have a very high metabolism, feeding on large amounts of nectar from flowers. At night, they go into a hibernation state called torpor to conserve energy.

1. kangaroo
   koala
2. platypus
   Gila monster

Koalas have an unusually limited diet. Range, too -- they're found exclusively in eastern Australia.

1. domestic cat
   desert fox
2. meerkat
   panda bear

Meerkats live in desert areas of southern Africa, like the Kalahari desert. They have a way of standing up on their hind legs that makes them look like the gossips and rubberneckers of the desert.

1. cobra
   antelope
2. kestrel
   swallow

The swallow is a bird which often has a forked tail. A similar bird with an un-forked tail is the martin.

1. mouse
   flea
2. tick
   vulture

A member of the arachnid class, ticks can carry a number of diseases. Lyme disease has stolen the headlines in recent years, though, because it affects people in northern climates (e.g. America and Canada) that usually evade parasitic diseases.

1. bumblebee bat
   Etruscan shrew
2. pgymy jerboa
   both #1 and #2

This honor (well, sort of) is shared between the two animals. The shrew weighs a little less -- about as much as a dime, if you can believe it!
