Fun facts & books about worms to keep you wiggling!

  • In one acre of land, there can be more than a million earthworms.
  • Earthworms are a source of food for numerous animals like birds, rats, and toads.
  • Worms do not have eyes but they can sense light, especially at their anterior (front end). They move away from light and will become paralyzed if exposed to light for too long.
  • A red worm is moist to the touch because of a slimy coating which keeps it from drying out. 
  • If a worm’s tail is cut off it will grow back. This is called regeneration. It will not become two separate worms. 
  • Worms move by contracting their circular and long muscles that run throughout their bodies.
  • The forward part of the worm’s body has five pairs of hearts. Blood is pumped by muscular action.
  • Worms have bristles on the underside of their bodies to assist them in moving throughout the soil.
    A worm does not have lungs. It gets oxygen through its skin and must remain moist to live.
  • Worms live where there is food, moisture, oxygen, and a favorable temperature. If they don’t have these things where they are, they’ll go someplace else.
  • Worms help make soil healthy.
  • Worms tunnel deeply in the soil and bring subsoil closer to the surface mixing it with the topsoil. Slime, a secretion of earthworms, contains nitrogen. Nitrogen is an important nutrient for plants. The sticky slime helps to hold clusters of soil particles together in formations called aggregates.
