资源简介

A

Lajamanu is a dry town in Australia. Can you imagine how surprised people were when live fish rained down from a dark gray cloud? It happens that there are similar cases in England and Honduras.

How do clouds make fish? The simple answer is that they don’t. There is a particular weather phenomenon called a waterspout. A waterspout is just like a tornado, which only forms above oceans, lakes, or rivers. Like a tornado, a waterspout moves in a circle at high speeds. When it moves above the water, it tends to carry the fish with it, as well as frogs or other small plants or animals.

Scientists couldn’t work it out at first. To make matters stranger still, the fish in Honduras were very much alive when they rained down to the ground, but they were all blind. In England and Australia, it rained fish and snakes, and none were blind. It was difficult to puzzle out, but the blind fish gave them a place to start.

Scientists knew that some fish that lived in deep, underground caves with no light sources often lost their eyesight. So when blind fish rained down on Honduras, scientists began to connect some dots. Clearly, these particular fish were pulled from an underground water source by force.

Historically, villagers thought the “fishes from the heavens” might be answers to prayers for food. But in 1990, a group of scientists in England happened to record what was happening when it rained fish from the sky and finally proved the fact of rains of fish. This huge breakthrough changed legends into true stories and provided scientific explanations for how fish came to live in deep caves.
