Raining fish from the sky
You might have heard on the news latelly that in Australia, Lajamanu to be exact, had a falling out of fish in their town the other day. This happened not only once, but two afternoons in a row.
Hundreds of small white fish fell from the sky on the 25th and 26th of February. While a odd occurence, its not an entirelly new one. Fish and other amphibians have been reportedly falling out the sky for centuries. Some live the ordeal and go on to live their lives.
The video below has 2 possible scenarios for events like this. Heavy precipitation, updrafts, and tornadoes going into small ponds of water are all possible culprits for such movement of live animals, and could also have played a huge part in our early existance.
Wikipedia also has an extensive article dealing with this issue of raining animals, and if you were like me were wondering if "Raining cats and dogs" had anything to do with that. Wiki's answer is a resounding NO. "The English language idiom "it is raining cats and dogs", referring to a heavy downpour, is of uncertain etymology, and there is no evidence that it has any connection to the "raining animals" phenomenon."
Cats and dogs cannot be picked up as easily as small flat fish or frogs, so this idiom really just means a heavy downpour. And while we know cats and dogs dont generally get along, it also means a heavy storm with thunder clashes.
