Lumbricus badensis

…is a species of giant Lumbricid earthworm, which is endemic to the upper-elevation spruce forests of Germany’s Black Forest. Reaching lengths of around 60 cm (24.6) in length L. badensis is one of the largest European species of earthworm. Like other smaller earthworms Lumbricus badensis tunnels underground (typically 2.5 m (8 ft) deep) and feeds on organic matter, aerating the soil and contributing to the formation of humus as it moves.

Lumbricus terrestris.Dissected. Rather young specimen, as indicated by the smallish size and the lack of a clitellum. The four white sacks after the ten lateral hearts contain the earthworm’s semen. This hermaphroditic group of animals prevents self insemination similar to Asteraceaean plants: It’s male organs are productive before the female ones.
