Did you know that worms are one big tongue? They taste the soil with their bodies… isn’t that amazing?
Worms don’t have any bones - they only have muscle.
They don't eat living plant tissue, and so don't hurt plants either. They truly are a gardener's best friend! Some people even keep them as pets, feeding them on kitchen scraps just so the worms can make them lots of lovely compost for their gardens.
Worms don't have legs but instead are covered in hairs or bristles that help them to move. They breathe through their skin.
They’ve existed for about 600 million years. There are about 34,000 different types of worm; many are so small you wouldn't be able to see them without a microscope!
