Earthworms are Quite Happy Underwater

We received a question from a reader who would like to know how much time a worm can spend underwater before drowning. The short answer is that, so long as the water has a high enough concentration of oxygen, most worms can live quite happily under water. When the soil that an earthworm is living in becomes very wet, it may choose to come to the surface to move around.
