Eisenia is a genus of earthworms (annelids), named after Swedish scientist Gustav Eisen.
The Sipuncula or Sipunculida is a class containing about 162 species of unsegmented marine annelid worms. The name Sipuncula is from the genus name Sipunculus, and comes from the Latin siphunculus meaning a "small tube".
Polychaeta is a paraphyletic class of generally marine annelid worms, commonly called bristle worms or polychaetes. Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. More than 10,000 species are described in this class. Common representatives include the lugworm and the sandworm or clam worm Alitta.
Vermicompost (vermi-compost) is the product of the decomposition process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast. This process is called vermicomposting, while the rearing of worms for this purpose is called vermiculture.
Blood worm or bloodworm is an ambiguous term and can refer to:
Lophotrochozoa is a clade of protostome animals within the Spiralia. The taxon was established as a monophyletic group based on molecular evidence. The clade includes animals like annelids, molluscs, bryozoans, brachiopods, and platyhelminthes.
Lessoniaceae are a family of kelp. Species of this family have transition zone with intercalary meristem subdivided so that there are a number of secondary stipes in addition to the primary stipe.
The clitellum is a thickened glandular and non-segmented section of the body wall near the head in earthworms and leeches, that secretes a viscid sac in which eggs are stored. It is located near the anterior end of the body, between the fourteenth and seventeenth segments. The number of the segments to where the clitellum begins and the number of segments that make up the clitellum are important for identifying earthworms. In microdrile earthworms, the clitellum has only one layer, resulting in a smaller quantity of eggs than that of the megadrile earthworms, which have larger multi-layered clitellum that have special cells that secrete albumin into the worms' egg sac.
Arame, sea oak is a species of kelp, of the brown algae, best known for its use in Japanese cuisine.
The Haplotaxida are one of two orders within the annelid subclass Oligochaeta, the other being the Lumbriculida. No real common name exists, but they are simply referred to as haplotaxids.
Eisenia fetida, known under various common names such as redworm, manure worm, 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 Clitellata are a class of annelid worms, characterized by having a clitellum - the 'collar' that forms a reproductive cocoon during part of their life cycles. The clitellates comprise around 8,000 species. Unlike the class of Polychaeta, they do not have parapodia and their heads are less developed.

The European nightcrawler is a medium-small earthworm averaging about 1.5 g when fully grown. Generally blueish, pink-grey in color with a banded or striped appearance, the tips of their tails are often cream or pale yellow. When the species has not been feeding, it is pale pink. The species is usually found in deep woodland litter and garden soils that are rich in organic matter in European countries. D. hortensis is sold primarily as a bait worm, but its popularity as a composting worm is increasing.
Verminephrobacter is a genus of Gram-negative bacteria that colonize the nephridia of earthworms within the family Lumbricidae. The first species in the genus, V. eiseniae, was isolated from the earthworm Eisenia foetida, and its description published in 2008. Their closest free-living relatives are bacteria of the genus Acidovorax.
E. gracilis may refer to:
Eisenia is a brown alga genus in the family Lessoniaceae. The genus is named for California Academy of Sciences curator, Gustav Eisen.
Gustavus Augustus Eisen was a Swedish-American polymath. He became a member of California Academy of Sciences in 1874 and a Life Member in 1883. In 1893, he became the 'Curator of Archaeology, Ethnology, and Lower Animals' at the Academy. He later changed titles to 'Curator of Marine Invertebrates'. In 1938, he was appointed as an 'Honorary Member', which is considered the highest honor from the Academy.
The annelids, also known as the segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches. The species exist in and have adapted to various ecologies – some in marine environments as distinct as tidal zones and hydrothermal vents, others in fresh water, and yet others in moist terrestrial environments.
Drilodefensins are a class of molecules first found in the gut of earthworms. They belong to the class of dialkylfuransulfonic acids and so far six different homologs have been found.
Pleistoannelida is a group of annelid worms that comprises the vast majority of the diversity in phylum Annelida. Discovered through phylogenetic analyses, it is the largest clade of annelids, comprised by the last common ancestor of the highly diverse sister groups Errantia and Sedentaria and all the descendants of that ancestor.
