Spirorbis Quasimilitaris
''Spirorbis'' is a genus of very small () polychaete worms, usually with a white coiled shell. Members of the genus live in the lower littoral and sublittoral zones of rocky shores. ''Spirorbis'' worms usually live attached to seaweeds, but some species live directly on rocks, shells or other hard substrates. ''Spirorbis'' was once thought to have a fossil record extending back into the Early Paleozoic, but now all pre-Cretaceous spirorbins are known to be microconchids. The earliest members of genus appeared in the Miocene, but Oligocene finds may also be possible. The genus contains the following species: * ''Spirorbis borealis'' Daudin, 1800 * '' Spirorbis corallinae'' De Silva and Knight-jones, 1962 * '' Spirorbis cuneatus'' Gee, 1964 * ''Spirorbis granulatus'' * '' Spirorbis incongruus'' * ''Spirorbis inornatus'' L'hardy and Quievreux, 1962 * '' Spirorbis knightjonesi'' Desilva, 1965 * '' Spirorbis lineatus'' * '' Spirorbis marioni'' (Caullery and Mesnil, 1897) * ''Spirorbis ...

Spirorbis Spirorbis
''Spirorbis spirorbis'' is a small (3–4 mm) coiled polychaete that lives attached to seaweeds and eel grass in shallow saltwater. They have a smooth, white, sinistral (left-handed) coiled shell encasing an orange body about 3 mm in length. The tube has a peripheral flange where it attaches to the substrate. The worm has a short abdominal region and a slightly broader thorax terminating in ten stiff tentacles, used to filter food from the water. One of the tentacles is slightly larger than the rest and shaped like a saucer, which is used as an operculum. This seals the opening of the shell and serves to protect the worm from predators and desiccation when out of water. It lives primarily on toothed wrack (''Fucus serratus'') and bladder wrack (''Fucus vesiculosus''), but is also found on the basal part of thongweed (''Himanthalia elongata''). Numerous individuals can be found on any one surface. ''Spirorbis spirorbis'' are cross fertilising hermaphrodites, who bro ...

10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of '' Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature, and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, even if they would otherwise satisfy the rules. The only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
