Answer Guide:

1.  A.  Koala. These marsupials exclusive found in Australia are extremely pickly eaters, preferring only a few types of leaves from the relatively small number of eucalyptus species comprising their overall habitat.

2.  C.  It can create large colonies containing more than one queen.  The genetic makeup of Argentine ants are so uniform that they can mingle in neighboring nests without being attacked, hence creating "supercolonies."

3.  B.  Elephant.  Although giraffes are obviously taller than elephants, these trunked mammals are actually heavier, weighing up to 12,000 kilograms (26,000 pounds).

4.  D. The males turn into parasites of females.  As the tiny male angler matures, its digestive system degenerates, leaving it unable to feed independently.  Once it finds a female, he quickly bites to her skin and releases an enzyme that digest the skin of his mouth to her body, fusing the pair until they are connected by blood vessels.  The male then become a parasite to the female, relying on her for sustenance while readily providing sperm whenever she releases eggs.

5.  C.  Caterpillar.  These tiny creatures eat so voraciously, it can increase its weight up to 10,000 times in just 20 days.

6.  A. Rhinoceros Beetle.  In proportion to its body size, this little creature can lift up to 850 times its own body weight. 

7.  B.  Tardigrade.  This insect-like creature can survive temperatures as low as -272°C (close to absolute zero) to as high as 151°C.  It can also withstand 1000 times more radiation than any other animal, survive for 120 years without water, and live in a vacuum.

8.  B.  Tapeworm.  Each section of its body can grow up to be a new tapeworm, and can even give birth to a million offsprings a day.

9.  D.  Vulture.  This bird can eat dead carcasses that contain anthrax, botulism, and even cholera.

10.  A.  Its offsprings eat each other even before they are born.  The Sand Tiger Shark hatches its eggs while inside the uterus.  While inside, the young develop and eat each other until only two are born.
