Head end dark brown to reddish brown lateral, dorsal pigmentation fading towards the back. [1] The worm has a hydrostatic skeleton and moves by longitudinal and circular muscular contractions.
The worms require loose soil to burrow in and soil moist enough for gas exchange. [3] Further requirements include such abiotic factors as pH and temperature. Various abiotic factors are significant to Lumbricus rubellus. pH is of particular importance; a range of 5.5 to 8.7 is acceptable with a preference for neutral soils. [4]

Bipalium species are predatory.Some species prey on earthworms, while others may also feed on mollusks. [10] [11] These flatworms can track their prey.

Probably the longest worm on confirmed records is Amynthas mekongianus that extends up to 3 m (10 ft) [10] in the mud along the banks of the 4,350 km (2,703 mi) Mekong River in Southeast Asia. From front to back, the basic shape of the earthworm is a cylindrical tube-in-a-tube, divided into a series of segments (called metameres ) that ...
