Here are some facts about earthworms:
Earthworms (Lumbricus terrestris) (also known as lob worms or garden worms) are nature‚Äôs ploughs and are crucial for soil aeration. In an acre of land between 16,000-30,000 lbs (7,200-13,500kg) of soil passes through earthworms and is deposited on the surface each year. No wonder archaeologists are so good at digging!
- How do worms travel? No, not on the underground, but by using their complex muscle system and hairs, called setae.
Earthworms do not have teeth, but use a gizzard to grind up pieces of food.
Worms don‚Äôt have eyes (except in cartoons!), but are sensitive to light.
Earthworms don‚Äôt have lungs, but instead ‚Äúbreathe‚Äù through their skin as long as it stays moist.
Earthworms are hermaphrodites ie their bodies contain both male and female reproductive organs.
- Not content with one heart, earthworms have no fewer than five.
