Opisthopora
Opisthopora is an order of mostly terrestrial worms. It is an order of the subclass Oligochaeta, which is distinguished by meganephridiostomal, male pores which open posteriorly to the last testicular segment. It includes the megadrile families of the mostly terrestrial true earthworms. There are currently eight known families. Families * Eudrilidae * Glossoscolecidae * Lumbricidae * Megascolecidae * Moniligastridae * Ocnerodrilidae * Octochaetidae Octochaetidae is a family of annelids The annelids (Annelida , from Latin ', "little ring"), also known as the segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches.

Oligochaeta
Oligochaeta () is a subclass of animals in the phylum Annelida, which is made up of many types of aquatic and terrestrial worms, including all of the various earthworms. Specifically, oligochaetes comprise the terrestrial megadrile earthworms (some of which are semiaquatic or fully aquatic), and freshwater or semiterrestrial microdrile forms, including the tubificids, pot worms and ice worms ( Enchytraeidae), blackworms ( Lumbriculidae) and several interstitial marine worms. With around 10,000 known species, the Oligochaeta make up about half of the phylum Annelida. These worms usually have few setae (chaetae) or "bristles" on their outer body surfaces, and lack parapodia, unlike polychaeta. Diversity Oligochaetes are well-segmented worms and most have a spacious body cavity (coelom) used as a hydroskeleton. They range in length from less than up to in the 'giant' species such as the giant Gippsland earthworm (''Megascolides australis'') and the Mekong worm (''Amynth ...

Eudrilidae
The Eudrilidae are a family of earthworms, mostly of Africa. One species, '' Eudrilus eugeniae'' (Kinberg, 1867), is widely distributed around the warmer parts of the world and historically cultured as the "African nightcrawler".Blakemore (2015). - http://africaninvertebrates.org/ojs/index.php/AI/article/view/395 The male pores of eudrilids are in segment 17, as is also typical of Ocnerodrilidae. Eudrilids differ from the family Megascolecidae and Acanthodrilidae in having euprostates, i.e., a muscular and possibly glandular development of the vasa deferentia (male ducts from testes) that open to the male pores. Eudrilids further differ from megascolecids, and ocnerodrilids in the development of internal fertilisation with the equivalent of the spermathecae opening directly to the ovisacs, allowing sperm to combine with the eggs from the ovaries via a female opening in segment 14.

Glossoscolecidae
The Glossoscolecidae are a large family of earthworms (annelids) which has native representatives in South and Central America. The species '' Pontoscolex corethrurus'' has a circumtropical distribution. They are found mostly in forest, but one species of earthworms lives primarily in coastal beach sand. The earthworms in this family can reach up to 2 m in length.

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 ...

Megascolecidae
The Megascolecidae is a taxonomic family of earthworms which is native to Madagascar, Australia, New Zealand and both South East Asia and North America. All species of Megascolecidae belong to the Clitellata class. Megascolecidae are a large family of earthworms and they can grow up to 2 meters in length. The intercontinental distribution of Megascolecidae helps in favouring the Continental Drift theory.Reynolds, J.W. 1995. The distribution of earthworms (Annelida, Oligochaeta) in North America. Pp. 133- 153 In: Mishra, P.C., N. Behera, B.K. Senapati and B.C. Guru (eds.). Advances in Ecology and Environmental Sciences. New Delhi: Ashish Publishing House, 651 pp. The distinctive feature that differs Megascolecidae from other earthworm families is their large size in comparison with other earthworm families. They are an essential part of maintaining soil structure, minor carbon sequestration, and maintaining terrestrial ecosystem balance. Megascolecidae is one of many families Anne ...
