Lurking in southern swamps from the Carolinas to Louisiana, alligators' place in folklore is both well-established and well-deserved. Get too close to one, and you'll find that their predatory abilities are no tall tale. What makes them so dangerous?

Question 2 of 11
An alligator's brain weighs:
8 or 9 grams, or about half a tablespoon
30 to 35 grams, or about 2 tablespoons
about 6 pounds, or twice as much as a human brain
...
A gator's brain might weigh less than the amount of cream you put in your morning coffee, but that doesn't mean you should take these scaly creatures lightly. Having such a small brain means that an alligator will eat anything that moves when it's time for a meal, whether it's a rodent, a bird or a child.

Question 3 of 11
How long can an alligator survive without eating?
between 48 and 72 hours
about two weeks
two to three years
...
Alligators can go a few years without eating, but that doesn't mean their reputation as one of nature's most dangerous predators isn't well-deserved. Why can they go so long between meals? It's because alligators are cold-blooded and store extra calories in fat deposits at the base of their tails. They can live off these fat reserves for a few years before going on the prowl again.

Question 4 of 11
American alligators are reptiles belonging to the order Crocodylia. How long has the basic Crocodylia body form existed?
1 million years
10 million years
more than 180 million years
...
Alligators walked the earth along with the dinosaurs; they've been around more than 180 million years. The reptiles from the order Crocodylia all have a similar body type, consisting of a large head, a lizard-like body, four stubby legs and a long tail.

Question 5 of 11
An average male alligator weighs:
300 pounds
600 pounds
2,000 pounds
...
Tipping the scales at about 600 pounds, the average male gator weighs about twice as much as its female counterpart and is about three feet longer (an average male is 11 feet, and an average female is 8 feet). Larger males can weigh more than 1,000 pounds, and one of the largest in captivity weighs more than 2,000 pounds.

Question 6 of 11
The spiky plates on an alligator's skin, also known as osteroderms, are:
bony pieces inside the skin that serve as armor
cartilage that softens in water and allows them to be more agile
special motion sensors that allow them to detect prey up to 200 yards away
...
Each of the jagged ridges on an alligator's back is actually a plate underneath the skin that serves as a natural suit of armor. A gator's many osteroderms make it very hard for potential predators to penetrate their skin.

Question 7 of 11
Alligators have two sets of eyelids. Their outer set is similar to human eyelids, while the inner set helps them:
play dead in the water and fool other animals
protect their eyes and allow them to see better underwater
navigate over long periods of time blind when they don 't feel like opening their eyes
...
Unlike their outer lids, which close top-to-bottom, an alligator 's inner eyelids close back-to-front, allowing them to preserve their eyes and see more clearly when they are underwater. This second set of eyelids is part of unique sensory system that allows an alligator to stay underwater for 10 to 20 minutes at a time.

Question 8 of 11
Alligators become fatigued very quickly because:
They don't use oxygen to power their muscles.
They live primarily in water, where physical exertion is much more difficult than it is on land.
They're lazy, and don't exert themselves often enough to stay in shape.
...
Alligators have small lungs and use anaerobic respiration when using their muscles. Humans, by contrast, use aerobic respiration in all activities except ones that are extremely demanding, such as sprinting or lifting weights. Anaerobic respiration requires energy to be generated faster than oxygen is available, thus making any human or gator who uses anaerobic respiration in physical activity fatigued faster. As a result, alligators can 't exert themselves for longer than 30 minutes before they 're completely drained of energy.

Question 9 of 11
Alligators use their tails to propel themselves up to _____ feet out of the water to catch their prey.
5

...
After lurking in the water for hours, an alligator can quickly and violently thrust itself up as high as 5 feet out of the water to snap at animals in low tree branches. Alligators eat nearly anything they can get their powerful jaws on.

Question 10 of 11
An alligator 's eggs are:
small and light blue, similar to a robin 's eggs
big, pink and soft
white, hard and a little bigger than a chicken egg
...
After breeding in the spring, a female alligator builds a nest and lays 30 to 50 white, hard eggs. The eggs ' incubation period is about 40 days, and the mother will protect her young from danger. Alligators are one of the only modern reptiles that care for their young.

Question 11 of 11
Alligators stop feeding when the temperature dips below _____ Fahrenheit.
40 degrees
50 degrees
70 degrees
...
Alligators become much less active as the temperature lowers in the winter. They stop feeding when the thermometer goes below 70 degrees Fahrenheit and become dormant in the cold winter months, burrowing their way into a den at the edge of a pond or river until the temperature goes up again.
