Lumbricidae
The Lumbricidae are a family of earthworms. About 33 lumbricid species have become naturalized around the world, 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'' and ''Helodrilus hachiojii''). An enigmatic species in Tasmania is ''Eophila eti''. Currently, 670 valid species and subspecies in about 42 genera are recognized. This family includes the majority of earthworm species well known to Europeans. Genera The family consists of the following genera: * ''Allolobophora'' Eisen, 1874 * '' Alpodinaridella'' Mršić, 1987 * ''Aporrectodea'' Orley, 1885 * ''Bimastos'' Moore, 1893 * '' Castellodrilus'' Qiu & Bouché, 1998 stat. nov. * '' Cataladrilus'' Qiu & Bouché, 1998 * '' Cernosvitovia'' Omodeo, 1956 * '' Creinella'' Mrši ...

Earthworm
An earthworm is a terrestrial invertebrate that belongs to the phylum Annelida. They exhibit a tube-within-a-tube body plan; they are externally segmented with corresponding internal segmentation; and they usually have setae on all segments. They occur worldwide where soil, water, and temperature allow. Earthworms are commonly found in soil, eating a wide variety of organic matter. This organic matter includes plant matter, living protozoa, rotifers, nematodes, bacteria, fungi, and other microorganisms. An earthworm's digestive system runs the length of its body. An earthworm respires (breathes) through its skin. It has a double transport system made of coelomic fluid that moves within the fluid-filled coelom and a simple, closed circulatory system. It has a central and peripheral nervous system. Its central nervous system consists of two ganglia above the mouth, one on either side, connected to a nerve running along its length to motor neurons and sensory cells in each s ...

Aporrectodea
''Aporrectodea'' is a genus of earthworms in the family Lumbricidae. The genus includes some of the most common earthworms in the Palearctic realm and in agricultural soils across the temperate regions of the world.Pérez-Losada, M., et al. (2009)Phylogenetic assessment of the earthworm ''Aporrectodea caliginosa'' species complex (Oligochaeta: Lumbricidae) based on mitochondrial and nuclear DNA sequences.''Molecular Phylogenetics and Evolution'' 52 293–302. Several species are found throughout the world today, having been widely introduced via agriculture. One of these widespread species, ''A. trapezoides'', was also transported across continents as a popular fishing bait.Fernández, R., et al. (2010)Life cycle and reproductive traits of the earthworm ''Aporrectodea trapezoides'' (Dugès, 1828) in laboratory cultures.''Pedobiologia'' 53 295–99. Some species of this genus are known to be important in the process of soil formation. Among the most familiar species is ''Aporrec ...

Bimastos
''Bimastos'' is a genus of lumbricid worm thought to be native to North America but has since been introduced to every continent apart from Antarctica. Recent molecular analysis has subsumed ''Dendrodrilus'' and ''Allolobophoridella'' under this genus. The clade holding ''Bimastos'' and '' Eisenoides'' seems to have diverged from Eurasian lumbricid '' Eisenia'' during the Late Cretaceous, approximately 69.2–76.1 years ago. This, along with the discovery of an earthworm cocoon attributed to ''B''. ''rubidus'' from lake sediment dated over 7,000 years old in Ontario, Canada contradicts the widely held notion that ''Bimastos'' and its junior synonyms are invasive worms from Europe which have colonized North America. It's ancestors likely entered North America via the Bering Land bridge Beringia is defined today as the land and maritime area bounded on the west by the Lena River in Russia; on the east by the Mackenzie River in Canada; on the north by 72 degrees north latitude ...

Lumbricus
The genus ''Lumbricus'' contains some of the most commonly seen earthworms in Europe among its nearly 700 valid species. 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 around 95-120 segments. * '' Lumbricus castaneus'' varies from chesnut to violet brown; brown or yellow ventrally, and has an orange clitellum. They are usually about 30–70 mm long, and have around 82–100 segments. * ''Lumbricus terrestris'' has several common names, including common earthworm, nightcrawler, and dew worm. It is strongly pigmented, brown-red dorsally, and yellowish ventrally. Setae are widely paired at both ends of the body. It is about 90–300 mm long, and has around 110–160 segments. * '' Lumbricus festivus'' is not found in large numbers. It is red-brown, lighter ventrally, iridescent dorsally. ...

Lumbricus Terrestris
''Lumbricus terrestris'' or the ''common earthworm'' 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. Through much of Europe, it is the largest naturally occurring species of earthworm, typically reaching 20 to 25 cm in length when extended. Common names Because it is widely known, ''L. terrestris'' goes under a variety of common names. In Britain, it is primarily called the common earthworm or lob worm (though the name is also applied to a marine polychaete). In North America, the term nightcrawler (or vitalis) is also used. In Canada, it is also called the dew worm, or "Grandaddy Earthworm". In several Germanic languages, it is called variants of "rain worm", for example in German ''Gemeiner Regenwurm'' ("common rain worm") or in Danish '' ...
