This diminutive volume answers dozens of fascinating questions like: Can earthworms see? Which end is which? Do they sleep? How do they have sex? What role might they play in space travel? Can you train them? And what on earth is "the mystery of the 'singing' earthworms"? Charles Darwin cited the earthworm as "the most important animal in the world"—read this and find out why!
