Various abiotic factors are significant to Lumbricus rubellus.
Further requirements include such abiotic factors as pH and temperature.
The worms require loose soil to burrow in and soil moist enough for gas exchange. Lumbricus rubellus naturally lives in soils high in organic matter, preferably dung and feces. rubellus reaches from segments 26 to 32 Habitat Members of this class are also defined by having permanent gonads. The segmentation of Lumbricus rubellus identifies the organism as a member of Phylum Annelida, while the enlarged segments towards the anterior of the organism called the clitellum denotes membership to Class Clitellata. Each segment contains four pairs of setae, or bristles, and the total number of segments per matured organism ranges from 95–105. Lumbricus rubellus, or the ' red earthworm', ranges from 25 millimetres (0.98 in) to 105 millimetres (4.1 in) in length and has smooth, reddish, semi-transparent, flexible skin segmented into circular sections. Their native distribution was mainland Europe and the British Isles, but they have currently spread worldwide in suitable habitats. They are usually about 25 millimetres (0.98 in) to 105 millimetres (4.1 in) in length, with around 95–120 segments. It is usually reddish brown or reddish violet, iridescent dorsally, and pale yellow ventrally.
