Lumbricus terrestris is a large, reddish worm species thought to be native to Western Europe, now widely distributed around the world (along with several other lumbricids). In some areas where it is an introduced species , some people consider it to be a significant pest for out-competing native worms.
Some species of earthworm can even use the prehensile prostomium to grab and drag items such as grasses and leaves into their burrow. An adult earthworm develops a belt-shaped glandular swelling, called the clitellum, which covers several segments toward the front part of the animal. This is part of the reproductive system and produces egg ...
Dung is the species preference. [2] With regards to light intensity, most earthworm species are photonegative to strong sources of light and photopositive to weak sources of light. [2] This is attributable to the effects of intense light, such as drying and a lack of food sources found above ground for earthworms.

The genus Lumbricus contains some of the most commonly seen earthworms in Europe among its nearly 700 valid species. [2] Characteristics of some commonly encountered species are: Lumbricus rubellus is usually reddish brown or reddish violet, iridescent dorsally, and pale yellow ventrally. They are usually about 25–105 mm in length, and have ...
The Lumbricidae are a family of earthworms.About 33 lumbricid species have become naturalized around the world, [1] but the bulk of the species are in the Holarctic region: from Canada (e.g. Bimastos lawrenceae on Vancouver Island) and the United States (e.g. Eisenoides carolinensis, Eisenoides lonnbergi and most Bimastos spp.) and throughout Eurasia to Japan (e.g. Eisenia japonica, E. koreana ...
Oligochaetes are well-segmented worms and most have a spacious body cavity (coelom) used as a hydroskeleton.They range in length from less than 0.5 mm (0.02 in) up to 2 to 3 metres (6.6 to 9.8 ft) in the 'giant' species such as the giant Gippsland earthworm (Megascolides australis) and the Mekong worm (Amynthas mekongianus).
They are also often the numerically dominant earthworm species in England, especially in neutral to base-rich grasslands and arable soils. [9] Because Allolobophora chlorotica is an endogeic worm, it builds complex lateral burrow systems through all layers of the upper mineral soil. This species of worm rarely comes to the surface, instead it ...
