Lumbricus is a genus of earthworms, which includes about 700 species. It is characterized by a completely split from the prostomium first body segment ( Peristomium ) and grooves, which form the edge of the prostomium and to groove extending between the first two segments ( tanylobische head anatomy). Testes and seminal ducts are surrounded by a small bag and available in the segments of nine, eleven and twelve. The bristles are tightly coupled. The Nephridialblasen are J-shaped.
