Why do worms crawl on concrete?
As worms breath through their skin, they can breath the oxygen in water, rather like a fish does. Scientists now believe the worms take advantage of the wetness to migrate.

Do worms crawl on the sidewalk?

What causes worms to die?
This happens because the worms’ homes in the soil got flooded, and the worms came to the surface in search of less soggy conditions. Once on the pavement, worms often get disoriented and cannot find their way back to the soil. They then dry up and die when the sun comes out.
Can worms survive being cut in half?
If an earthworm is split in two, it will not become two new worms. The head of the worm may survive and regenerate its tail if the animal is cut behind the clitellum. But the original tail of the worm will not be able to grow a new head (or the rest of its vital organs), and will instead die.
