Fridericia is a genus of annelids of the family Enchytraeidae. [1] The genus was described in 1889 by Wilhelm Michaelsen. [1] [2]
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, and freshwater or semiterrestrial microdrile forms, including the tubificids, pot worms and ice worms (Enchytraeidae), blackworms (Lumbriculidae) and several interstitial marine worms.
Ice 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 glacial ice. They include the only annelid worms known to spend their entire lives in glacial ice, and some of the few metazoans to complete their entire life cycle at conditions below 0 °C (32 °F).
Lars Michaelsen is a Danish former professional road bicycle racer who last rode for Team CSC. He got his break through in his second year as a professional, when he won the 1995 edition of Gent–Wevelgem. In the 1997 Vuelta a España he won stage 1 and wore the leader's jersey for three days. In 2002 he finished fifth in Paris–Roubaix, a result he would duplicate in 2005. In the 2006 Paris–Roubaix he was once again in the group of favourites, but he helped teammate Fabian Cancellara win the race and finished 19th himself. In his last race, the 2007 Paris–Roubaix, he finished 11th after a strong race, where only a mechanical failure prevented him from following the favorites. Again a teammate, Stuart O'Grady, won the race. Michaelsen rode at four Olympic Games.
Enchytraeidae is a family of microdrile oligochaetes. They resemble small earthworms and include both terrestrial species known as potworms that live in highly organic terrestrial environments, as well as some that are 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, which is commercially bred as aquarium fish food.
Helena Iren Michaelsen is a Norwegian singer-songwriter, known as the frontwoman for European symphonic metal band Imperia and her solo project Angel. She was the lead singer of the Gothic metal band Trail of Tears from 1997 to 2000, and was briefly the singer of Dutch symphonic metal band Sahara Dust.
Spenceriella is a genus of worms in the family Megascolecidae that is now included in the prior genus Anisochaeta although some other species are transferred to Celeriella.
The Acanthodrilidae are an ancient and widely distributed family of earthworms which has native representatives in Australia, New Zealand, South Africa, South America, and North America. No native species are known from India nor Asia. The family possibly shows a pre-Pangaean distribution.
Stolidobranchia is an order of tunicates in the class Ascidiacea. The group includes both colonial and solitary animals. They are distinguished from other tunicates by the presence of folded pharyngeal baskets. This provides the etymology of their name: in ancient Greek, στολίς, ίδος means the "fold" of a cloth. Stolidobranchian sea squirts are also characterized by the complete absence of an abdomen. The abdominal organs of other tunicates are instead located to one side of the pharyngeal basket in this group.
Aplousobranchia is an order of sea squirts in the class Ascidiacea, first described by Fernando Lahille in 1886. They are colonial animals, and are distinguished from other sea squirts by the presence of relatively simple pharyngeal baskets. This provides the etymology of their name: in ancient greek, ἁ.πλοος-ους (ha.ploos-ous) means "simple". The posterior part of the abdomen contains the heart and gonads, and is typically larger than in other sea squirts.
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.
