Enchytraeidae
Enchytraeidae is a family of microdrile oligochaeta, oligochaetes. They resemble small earthworms and include both terrestrial species known as potworms that live in highly organic Ecoregion#Terrestrial, terrestrial environments, as well as some that are Marine (ocean), marine. The peculiar genus ''Mesenchytraeus'' is known as "ice worms", as they spend the majority of their lives within glaciers, only rising to the surface at certain points in the summer. Enchytraeidae also includes the Grindal worm (''Enchytraeus buchholzi''), which is commercially bred as aquarium fish food. Selected genera Enchytraeidae genera include: * ''Achaeta (annelid), Achaeta'' František Vejdovsky, Vejdovský, 1878 * ''Archienchytraeus'' Eisen, 1878 (''nomen dubium'') * ''Buchholzia (annelid), Buchholzia'' Michaelsen, 1886 * ''Cernosvitoviella'' Nielsen & Christensen, 1959 * ''Christensenidrilus'' Dózsa-Farkas & Convey, 1998 (= ''Christensenia'' Dózsa-Farkas & Convey, 1997 (''non'' Brinck 1945: Chris ...

Mesenchytraeus
Ice worms (also written as ice-worms or iceworms, or also called glacial or glacier worms) are enchytraeid annelids of the genus ''Mesenchytraeus''. The majority of the species in the genus are abundant in gravel beds or the banks of riverine habitats, but the best-known members of the genus are found in glacier, glacial ice. They include the only annelid worms known to spend their entire lives in glacier, glacial ice, and some of the few metazoans to complete their entire life cycle at conditions below . They were discovered in a wide range of environments, which include level snowfields, steep avalanche cones, crevasse walls, glacial rivers and pools, and hard glacier ice. These organisms are unique in that they can simply move between tightly packed ice crystals. They utilize setae, which are small bristles found on the outside of their bodies, to grip the ice and pull themselves along. The genus contains 77 species, including the North American glacier ice worm (''Mesench ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oligochaeta
Oligochaeta () is a subclass of soft-bodied 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 ...

Grania
''Grania'' is a genus of marine annelid worms in the class Clitellata. They are found at many depths in sands throughout the world. They are generally about in length and mostly colorless or white, though ''Grania colorata'', a recently discovered species found in the Great Barrier Reef The Great Barrier Reef is the world's largest coral reef system, composed of over 2,900 individual reefs and 900 islands stretching for over over an area of approximately . The reef is located in the Coral Sea, off the coast of Queensland, ..., is green. Species There are 72 species in the genus ''Grania'' which have been identified.

Earthworm
An earthworm is a soil-dwelling terrestrial invertebrate that belongs to the phylum Annelida. The term is the common name for the largest members of the class (or subclass, depending on the author) Oligochaeta. In classical systems, they were in the order of Opisthopora since the male pores opened posterior to the female pores, although the internal male segments are anterior to the female. Theoretical cladistic studies have placed them in the suborder Lumbricina of the order Haplotaxida, but this may change. Other slang names for earthworms include "dew-worm", "rainworm", "nightcrawler", and "angleworm" (from its use as angling hookbaits). Larger terrestrial earthworms are also called megadriles (which translates to "big worms") as opposed to the microdriles ("small worms") in the semiaquatic families Tubificidae, Lumbricidae and Enchytraeidae. The megadriles are characterized by a distinct clitellum (more extensive than that of microdriles) and a vascular system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grindal Worm
''Enchytraeus buchholzi'', Grindal worms, (described by František Vejdovsky in 1879) are enchytraeid oligochaete worms. They are found in temperate meadows and disturbed roadside verges. The scientific name probably covers a group of morphologically indistinguishable species, which would complicate their use as test species in substitution for '' E. albidus'', a species commonly cultivated in the laboratory for toxicity tests, according to OECD.''OECD Guidelines for the Testing of Chemicals'' 220, adopted 13 April 2004 For aquarists "Grindal worms" are treated as smaller relatives of whiteworms, but usually only grow to about 10 mm and thus are an ideal size for most small freshwater fish, both adults and larger fry. Mrs. Morten Grindal, of Sweden, who was prominent in the development of culturing techniques for whiteworms, was apparently the first aquarist to isolate this smaller species. Grindal worms can be cultured exactly as whiteworms but are a much more adaptable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
