Interesting facts about earthworms

Written by Matthew on May 18th, 2013
  • In one acre of land, there can be more than a million earthworms.
  • The largest earthworm ever found was in South Africa and measured 22 feet from its nose to the tip of its tail.
  • 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.
  • Charles Darwin spent 39 years studying earthworms more than 100 years ago.
  • Worms are cold-blooded animals.
  • Earthworms have the ability to replace or replicate lost segments. This ability varies greatly depending on the species of worm you have, the amount of damage to the worm and where it is cut. It may be easy for a worm to replace a lost tail, but may be very difficult or impossible to replace a lost head if things are not just right.
  • Baby worms are not born. They hatch from cocoons smaller than a grain of rice.
  • The Australian Gippsland Earthworm grows to 12 feet long and can weigh 1-1/2 pounds.
