The antics in Sharknado, which involve tornadoes filled with man-eating sharks, might seem beyond ridiculous. (And well, for the most part, they are.) But the film's central premise — that a tornado could pluck creatures from the sea and deposit them on land — actually has some scientific merit.
In fact, there are numerous accounts throughout history of animals raining from the sky, most likely the result of getting sucked up by a tornado. Although no shark tornadoes have ever been reported, tornadoes and waterspouts have been known to lift animals like fish, frogs and even alligators and drop them ashore, often still alive and kicking.
Mother Nature Network has information, links and examples of fish, frogs, jelly fish, worms and even alligators raining down from the sky:
AlligatorsThis story might be the closest thing to a real-life sharknado. According to a report from 1887 in the New York Times: "Dr. J. L. Smith, of Silverton Township, while opening up a new turpentine farm, noticed something fall to the ground and commence to crawl toward the tent where he was sitting. On examining the object he found it to be an alligator."
Smith went on to find himself surrounded by eight alligators in total, which had apparently been dropped from the sky by a distant waterspout. If his account is to be believed, then this was history's first and only documented case of a genuine, no joke, gatornado.
