- There are over 3000 different kinds of earthworms
- Annelids – the phylum of which Earthworms are part, are good swimmers.
- Some in Australia can grow to over 3 meters long!
- The scientific name for the common earthworm is Lumbricus terrestris.
- Earthworms have no eyes or ears, but are very sensitive to vibrations.
- Worms are often eaten by hedgehogs, birds, frogs and toads.
- There are about 3 million worms per acre of grassland, that is a lot of worms.
- Fossils are rare due to the soft body.

How do earthworms move?
If you look at an earthworm you can see the body is made up of lots of segments, underneath the segments are muscles which contract and relax allowing the worm to move.
How do earthworms breathe?
They absorb oxgen through pores in their skin. This is why they come up to the surface when it rains, they need to come to the surface to breathe if their burrow becomes waterlogged.
Why do we need worms?
Worms are essential for the wellbeing of plants. The tunnels allow water to reach the roots and the process of the worm eating soil releases nutirents needed by the plants. Worms are also a source of food for other animals.
Did you know worms were such amazing creatures?For a light hearted look at the life of a worm, we loved this hilarious book, Diary of a Worm.
Earthworm Activities for kids
We all learned a lot from making our own wormery.
