Opening a Can of Worms

Lumbricus terrestris: the common earthworm. Although, on closer inspection, there's more than meets the eye.

How many different types can you spot in your garden? Take care when you're handling them - no tug-of-war, please! Make sure they're not out of the ground for too long. Perhaps sprinkle them with water when your survey's done.
