Mesenchytraeus
Ice worms (also written as ice-worms or iceworms) 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 (''Mesenchytraeus solifugus'') and the Yosemite snow w ...

Mesenchytraeus Solifugus
''Mesenchytraeus solifugus'', commonly called an ice worm, is a species of Oligochaeta, oligochaete worm that inhabits coastal glaciers in northwestern North America. ''M. solifugus'' is dark brown and grows to about 15 mm long and 0.5 mm wide. It has a high population density and is common in suitable habitat. It can only survive at temperatures of approximately –7 °C to 5 °C. The ice worm is studied for its ability to survive in low temperatures. It has heavy pigment, absorbing most colors; however, it burrows into the glacier to avoid strong sunlight. History and taxonomy This species was first reported from Muir Glacier in Alaska. Carlo Emery named it ''solifugus'' in 1898, meaning "fleeing from the sun". Phylogeny suggests that it evolved from an aquatic ancestor. Description Ice worms are the only known Psychrophile, psychrophilic annelids. Adult ice worms are approximately long. They live their entire lives in snow or ice. The ice worm’s dark ...

Enchytraeid
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 live in glaciers and will die if exposed to temperatures a few degrees above freezing. Apart from these, the best-known species is probably the Grindal Worm (''Enchytraeus buchholzi''), which is commercially bred as aquarium fish food. Selected genera Enchytraeidae genera include:WoRMS (2010) * ''Achaeta'' František Vejdovsky, Vejdovský, 1878 * ''Archienchytraeus'' Eisen, 1878 (''nomen dubium'') * ''Cernosvitoviella'' Nielsen & Christensen, 1959 * ''Christensenidrilus'' Dózsa-Farkas & Convey, 1998 (= ''Christensenia'' Dózsa-Farkas & Convey, 1997 (''non'' Brinck 1945: Christensenia (beetle), preoccupied)) * ''Cognettia'' Nielsen & Ch ...

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

Snow Algae
Snow algae are a group of freshwater micro-algae which grow in the alpine and polar regions of the earth. These algae have been observed to come in a variety of colors associated with both the individual species, stage of life or topography/geography. This variation is associated with both albedo differences of the snowy habitat and the presence of micro-invertebrates. Snow algae play a critical role in the trophic organization as primary producers who in turn are consumed primarily by tardigrades and rotifer The rotifers (, from the Latin , "wheel", and , "bearing"), commonly called wheel animals or wheel animalcules, make up a phylum (Rotifera ) of microscopic and near-microscopic pseudocoelomate animals. They were first described by Rev. John H ...s. Snow algae have also been found to travel great distances being carried by winds. References Algae Aquatic ecology {{Alga-stub ...
