Worms in the rain

Have you ever noticed that when it rains, the worms come up to the surface? Do you know why? They do that because they drown in the water that goes underwater. But, if they stay at the surface too long they will dry and die.

Francisca Cignetti, Maria Black, Paula Beamonte, Emilia Volpacchio

What does a worm prefer?

Light or dark?
Dark, because in the dark soil is more fresh and humid.
Wet or dry?
Neither, they need at least 70% of humidity.
On top of soil or underground?
Underground, because the light hurts them. Also because it is fresh in the soil.
Alkaline or acid soil?
Alkaline, because it is a soil with a lot of minerals.
Hot or cold?
Neither, it should be warm.

The Anatomy of a Worm

Worms do not have the same organisms as we do. We have a brain, eyes, legs, ears, arms, neck, lungs, shoulders, and nose, but worms do not. Another difference is that we have one heart and worms have five. The last difference is that since worms do not have eyes, they need something to find their way, so they use photoreceptors that sense light.

Maria Black - Francisca Cignetti - M.Emilia Volpacchio

Did you know that…?

• A worm has five hearts?
  They have five hearts! All of these hearts pump blood through their blood vessels just like your one heart.
  
• A worm doesn’t have eyes?
  Even though worms don’t have eyes, they can sense light, especially at their anterior (front end). They don’t like light!!
  
• A worm has both, male and female organ?
  Worms are hermaphrodites. Each worm has both male and female organs. Worms mate by joining their clitella (swollen area near the head of a mature worm) and exchanging sperm.
  
• A worm can grow only so long?
  A Lumbricus terrestris will be from 90-300 millimeters long.
