Earthworms are clitellate annelids living mainly in soils, although some species inhabit freshwater environments. Their role is largely recognized as crucial as within the soil organic matter decomposition processes than in soil bioturbation and nutrient cycling.

Drilobase is a database resulting from a collaborative work between worldwide members of the earthworm scientific community. Data are given per taxonomic unit. Please keep in mind that such a tool is always a "work in progress" and never a finished product. As such it is subject to change.

Identification of earthworms is extremely complex and requires considerable specialised expertise. Some taxa require DNA sequencing. We do not provide such a service.
