Earthworms On Rainy Days:

You must have seen a great number of earthworms around your house, on the roads and on the playground after a rainfall. Most people think that they come out from their underground homes’ after rain because their burrows are flooded with water. But earthworms aren’t afraid of water. They can live in water for months together, and in fact, die if their skin is dried out.
