EISENIA FOETIDA>PUBLISHER=FAUNA EUROPAEA, 2004, |synonyms = Eisenia foetida (older spelling) }}Eisenia fetida, known under various common names such as manure worm,WEB, Catalogue of Life : Eisenia fetida (Savigny, 1826),www.catalogueoflife.org/annual-checklist/2019/details/species/id/747f08e6625bd7305b38274efe605b4e, 2021-01-26, www.catalogueoflife.org, redworm, brandling worm, panfish worm, trout worm, tiger worm, red wiggler worm, etc., is a species of earthworm adapted to decaying organic material. These worms thrive in rotting vegetation, compost, and manure. They are epigean, rarely found in soil. In this trait, they resemble Lumbricus rubellus.The red wiggler is reddish-brown in color, has small rings around its body, and has a yellowish tail.WEB,gardenplantslife.com/identify-red-wigglers-worms/, Red wiggler Body appearance, Groups of bristles (called setae) on each segment of the worm move in and out to grip nearby surfaces as it stretches and contracts its muscles to push itself forward or backward.E. fetida worms are native to Europe, but have been introduced (both intentionally and unintentionally) to every other continent except Antarctica. E. fetida also possesses a unique natural defense system in its coelomic fluid; cells called coelomocytes secrete a protein called lysenin, which is a pore-forming toxin, which is able to permeabilize and lyse invading cells. It is best at targeting foreign cells whose membranes contain significant amounts of sphingomyelin. (Lysenin is also toxic to organisms lacking sphingomyelin in their cell walls, including Bacillus megaterium, though the pathway is not understood).JOURNAL, Bruhn, Heike, Winkelmann, Julia, Andersen, Christian, Andrä, Jörg, Leippe, Matthias, 2006-01-01, Dissection of the mechanisms of cytolytic and antibacterial activity of lysenin, a defence protein of the annelid Eisenia fetida,www.sciencedirect.com/science/article/pii/S0145305X05001734, Developmental & Comparative Immunology, en, 30, 7, 597–606, 10.1016/j.dci.2005.09.002, 16386304, 0145-305X, Uses E. fetida is used for vermicomposting of both domestic and industrial organic waste.JOURNAL, Albanell, E., Plaixats, J., Cabrero, T., 1988, Chemical changes during vermicomposting (Eisenia fetida) of sheep manure mixed with cotton industrial wastes, Biology and Fertility of Soils, 6, 3, 10.1007/BF00260823, 0178-2762, 21470644, JOURNAL, Orozco, F.

This is presumably an antipredator adaptation.BOOK, Townsend, Craig, Ebizuka, Yutaka, Natural products structural diversity-I, secondary metabolites : organization and biosynthesis, 2010, Elsevier, Boston, 978-0-08-045381-1, 1st, 1, 393, (File:Eisenia_fetida_HC1.jpg|thumb|right|200px|Close-up of E. fetida with visible bristles) Related species E. fetida is closely related to E. andrei, also referred to as E. f. andrei. The only simple way of distinguishing the two species is that E. fetida is sometimes lighter in colour. Molecular analyses have confirmed their identity as separate species, and breeding experiments have shown that they do produce hybrids.JOURNAL, Plytycz, Barbara, Bigaj, Janusz, Panz, Tomasz, Grzmil, PaweÅ‚, 2018-09-21, Asymmetrical hybridization and gene flow between Eisenia andrei and E. fetida lumbricid earthworms, PLOS ONE, en, 13, 9, e0204469, 10.1371/journal.pone.0204469, 6150523, 30240427, 2018PLoSO..1304469P, free, The mitochondrial genetic characteristics of the Irish population of E. fetida could be the result of reproductive isolation, so suggests that this sample may constitute an unrecognized species or subspecies of E. fetida.JOURNAL, Pérez-Losada, Marcos, Eiroa, Julio, Mato, Salustiano, Domínguez, Jorge, Phylogenetic species delimitation of the earthworms Eisenia fetida (Savigny, 1826) and Eisenia andrei Bouché, 1972 (Oligochaeta, Lumbricidae) based on mitochondrial and nuclear DNA sequences, Pedobiologia, August 2005, 49, 4, 317–324, 10.1016/j.pedobi.2005.02.004, Reproduction (File:Redwiggler-copulation-compost.jpg|thumb|right|200px|E. fetida copulating in a compost bin)As with other earthworm species, E. fetida is hermaphroditic, and uniparental reproduction is possible, even if usually the reproduction is between copulating individuals.JOURNAL, Domínguez, Jorge, Velando, Alberto, Aira, Manuel, Monroy, Fernando, 2003-01-01, Uniparental reproduction of Eisenia fetida and E. andrei (Oligochaeta: Lumbricidae): evidence of self-insemination: The 7th international symposium on earthworm ecology · Cardiff · Wales · 2002,www.sciencedirect.com/science/article/pii/S0031405604702334, Pedobiologia, en, 47, 5, 530–534, 10.1078/0031-4056-00224, 0031-4056, The two worms join clitella, the large, lighter-colored bands which contain the worms’ reproductive organs, and which are only prominent during the reproduction process. The two worms exchange sperm. Both worms then secrete cocoons, which contain several eggs each. These cocoons are lemon-shaped and are pale yellow at first, becoming more brownish as the worms inside become mature. These cocoons are clearly visible to the naked eye. At 25°C, E. fetida hatches from its cocoon in about 3 weeks.
