The common American and European earthworm, Lumbricus terrestris, up to 10 in. (25 cm) long, with about 150 segments, is used for laboratory dissection and study. Earthworms are also used as live bait and are eaten by some peoples—such as the Maoris, who consider certain species delicacies.
The earthworm's greatest service, however, of immense importance to agriculture, is aerating and mixing the soil. Earthworm castings bring to the surface from 7 to 18 tons of soil per acre annually.
This invaluable function of the earthworm was first pointed out in a detailed study by Charles Darwin. Enrich your soil and improve aereation the natural way - with red wiggler earthworms. Red wigglers tunnel their way through the soil feeding on dead and decaying organic matter and turning it into a rich compost that helps keep plants and soil healthy.
