Can you really escape an alligator if you run in a zigzag?

Much like the cheetah, the alligato­r is an incredibly fast runner. Perhaps you've seen one rise up on its long, muscular legs and sprint 500 yards (457 meters) across a wide-open field after fleeing prey.

No? You've never witnessed such a thing? What you've probably witnessed is somethi­ng like this: You're standing by a lagoon, checking out a pelican, when you notice two small bumps that protrude from the water. After you take note of the "Don't Feed the Alligators" sign, you put two and two together and decide those bumps are the eyes of said creature lazily floating in the lagoon. You're frightened for a moment, but then you remember the classic adage: You can escape an alligator if you run in a zigzag. And this brings you comfort.


But should it? This saying, which is so old and so widespread that it's virtually impossible to determine where or why it was ever started, implies a couple of things: One, it implies that an alligator is likely to chase you a long distance on land. Two, it implies that alligators can run faster than humans -- at least when they're running in a straight line.

The truth is, although alligators are frighteningly quick, they're not cheetah fast and they don't like to run long distances. It's very rare for an alligator to chase a human on dry land. And the average human could easily outrun an alligator, zigzagging or not -- it tops out at a speed of around 11 miles per hour (18 kph), and it can't maintain that speed for very long [source: San Diego Zoo].

More importantly, gaining on prey via a long sprint is not the alligator's attack tactic. The alligator prefers to sneak up on its prey in the water. It's a much faster swimmer than runner -- it can swim 20 miles per hour (32 kph) [source: San Diego Zoo]. And it's silent as it moves through water. Its eyes are set on top of its head, so it can swim while watching what's happening on the surface. It can also remain underwater for extended periods of time and hold its breath for up to one hour.

So sure, you could probably escape an alligator if you ran in a zigzag. You probably also could escape one if you ran in a straight line. But the likelihood that an alligator would ever chase you on dry land is so low that the old adage is more joke than genuine advice. It simply doesn't apply.

Why wouldn't an alligator chase you? And how would it attack you instead? Find out on the next page.


Why Alligators Don't Like to Eat Humans

Not only are alligators not likely to chase you a long distance on dry land, they're not likely to attack you at all. ­Alligators prefer an easy meal. They're patient hunters and will stalk their prey in the water for hours before attacking. But once they attack, they don't want to do a lot of work. Prey that fights back is typically abandoned. And they don't like to attack anything they can't swallow in one gulp. Even large alligators typically choose prey that's relatively small, which is good news for adult human beings.

Small alligators make up the majority­ of the alligator population. An­ alligator that is less than 5 feet (1.5 meters) long will typically eat c­rawfish, small snakes and turtles. They don't even present a threat to small dogs. Small all­igators ­are not a threat to humans and won't attack people under normal circumstances.


Sometimes people think small alligators -- say, smaller than 3 feet (0.9 meters) -- will make a good pet. In fact, trying to capture an alligator is the most common way people get bitten by one. Even small alligators have more than 80 razor-sharp teeth. While a bite may not be life threatening, it still requires a visit to the hospital.

Large alligators are less common, but they're the greatest threat to humans because they're big enough to size us up as a legitimate meal. A full-grown alligator that is between 8 and 11 feet (2.4 and 3.4 meters) could weigh up to 1,000 pounds (453 kilograms) [source: Smithsonian National Zoological Park]. Even though these alligators are a threat to humans, they're still wary of us. Alligators would prefer to avoid interactions with people altogether. When people witness an alligator snapping its jaws and growling, they assume it's preparing to attack. In fact, this is defensive posturing.

Still not convinced that alligators don't hunt humans? Look at the numbers. There's an average of four alligator attacks in the United States each year (despite the fact that the state of Florida alone averages 12,000 complaints about the reptiles annually). Here's another number to think about: Since 1948, the Fish and Wildlife Conservation Commission has received reports of 356 alligator attacks on humans. Twenty-five of those attacks were fatal, and in nine cases it's believed that the victims were deceased before the alligators ate them for dinner.

Of course, there are exceptions to every rule, right?


What to Do if You're Attacked by an Alligator

Alligators won't run you down on the street. But th­ey will sneak up on you in the water. Although it feels like an unfortunate surprise for the victim, the alligator's style of attack­ is very predictable. It latches onto its prey and begins what is known as the death roll. It rolls over and over until its prey is dead, usually by drowning but occasionally from loss of blood.

The alligator then juggles the prey around in its mouth so that it can toss it down its throat. The massive jaw that allows it to hang onto its prey so securely also prevents it from easily chewing and swallowing. This is one reason why larg­e prey presents a problem for an alligator. To eat something large, the alligator must rip pieces from the prey and swallow them separately. And it doesn't like that task.


If you think an alligator is approaching you, run. It doesn't matter if you run in a zigzag or a straight line. You should be able to easily outrun an alligator. If it seems to be gaining on you, don't panic. Alligators not only have little endurance, but they also don't really care to pursue their prey. If an alligator misses its first opportunity to grab its victim, it typically moves on to something else.

If you're caught unaware at the ed­ge of the water or in the water, which is a more likely scenario, you have less chance to evade the alligator. In the water, the alligator has home field advantage; it's got you right where it wants you. So a water attack is a worst-case scenario. If you feel the alligator's jaw clamp down on you, resist. Don't waste time trying to pry its jaw open, which is nearly impossible. Instead scream, splash and generally create as much confusion for the alligator as possible. As soon as you can get a clear shot, drive your thumb or fingers directly into its eye. This is the most sensitive area of the alligator's body, and the combination of pain and surprise should be enough to cause the alligator to release you.

Occasionally, a bad-tempered alligator may not give up the fight. As a last ditch effort, you may want to play dead. The alligator releases dead prey as it prepares to maneuver it back into its throat. This can provide you the opportunity to escape. It's a risky plan, however, and if the alligator has you in the water, you should do everything possible to prevent it from going into a death roll.

The words "death roll" don't sound good, do they? It's probably best to avoid a meeting with an alligator altogether. Find out how to play it safe in gator country on the next page.


Staying Safe in Alligator Territory

Just because alligators have no natural desire to eat us for dinner, doesn't mean we don't need to be cautious in their presence. If you live or are vacationing in alligator country, there are some ways to decrease the likelihood of an unpleasant encounter.

Many human victims of alligator attacks are small children who are wading or playing in water without adult supervision.


Alligators may attack because they're hungry, but that's not the most common reason. As humans continue to encroach on wildlife habitat, reducing the alligator's natural food sources, it's expected that these types of attacks may increase. The two main reasons that an alligator attacks a human are because it's protecting its territory or it's angry.

An adult male is territorial during mating season, which is early- to mid-summer. If he feels threatened or startled, he may attack. A female with her young may attack if she views a human as a threat to her offspring. In fact, attacks often occur when a human tries to capture or pet young alligators, not realizing that mom is nearby.

Many attacks occur as a result of people teasing or trying to capture alligators. Throwing sticks and rocks at alligators may seem harmless, but doing so creates a dangerous situation for both the person and the alligator.

How do you enjoy yourself in areas where alligators may be present? Swim in areas where the water is clear and the banks are well groomed. Alligators may be lurking in areas where the water is murky and the banks are overgrown with weeds or brush. No matter how inviting the water, it makes sense to avoid it during times when alligators are most active. They typically feed at dusk and through the night, and may still be active at dawn.

If you have children or small pets with you, keep them away from the water's edge. Only allow them into the water if you or another adult are present to supervise them (or better yet, don't allow them in the water at all). Also, if you've been fishing, don't clean the fish at the water's edge or throw the discarded parts into the water.

Finally, if you see an alligator, get out of the water. Warn others in the area, and no matter how small the alligator is, don't attempt to pet, feed or capture it. By following these tips you shouldn't have to worry whether you'll run in a zigzag, up a tree or down a hill to avoid an alligator.

Alligator Run FAQ

How fast can an alligator run on land?
Most experts believe that the average alligator can run up to 11 mph (18 kilometres) on dry land for a brief amount of time. However, due to their weight, they run in a zigzag motion that slows them down and tires them out pretty quickly.
How fast can alligators swim?
An alligator can swim up to 20 miles (32 kilometres) per hour.
Do alligators attack on dry land?
Alligators are lazy predators as they like an easy meal. Stalking their prey in the water for hours before they finally attack is their specialty. They tire quickly on land, so it is highly unlikely for them to chase or attack a human.
What do you do when an alligator chases you?
Even though it is unlikely for an alligator to chase you, if such a situation arises, run as fast as you can. Since they have almost no endurance on land, you’re extremely likely to outrun it. If it’s close and manages to clamp down on you, jab your fingers into it’s eyes and scream, splash, and make it seem more trouble than it’s worth to try to “death roll” you.
What is a safe distance from an alligator?
Stay as far away from an alligator as you can. If it hisses at you, it means you are standing too close. The safest distance from an alligator is about 60 feet.
