"It’s raining cats and dogs" is just an expression, and Sharknado was just a movie. But throughout history, there have been instances of animals falling from the sky. When it’s birds or insects, we assume that they were flying, but how do you account for all those other creatures?
Over the years many different animals have reportedly fallen from the sky. Tadpoles over Japan; spiders over Brazil; frogs over Serbia, ancient Egypt and Kansas City; brown worms over Indiana; scarlet worms over Massachusetts; red worms over Sweden; snails over England; a shower of raw meat (thought to be venison or mutton) over Kentucky; blackbirds over Arkansas; eels over Alabama; snakes over Tennessee and fish over Australia, India and Honduras.
Although they all fall into the freakish category of animals falling from the sky, there are many different explanations for the phenomena. Read about some of these accounts, and the reasonable explanations of how they happened, at Modern Farmer.
