Spirorbis Incongruus
''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-Bathonian (Middle Jurassic) 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, 189 ...

Spirorbis Spirorbis
''Spirorbis spirorbis'' or ''Spirorbis borealis'' is a small (3–4 mm) coiled sedentary marine Polychaeta, polychaete worm in the Serpulidae family that lives attached to seaweeds and Zostera, eel grass in shallow saltwater. It is commonly called the sinistral spiral tubeworm and is the type species of the genus ''Spirorbis''. ''S. spirorbis'' is a cross-fertilising hermaphrodite that broods its young in a tube attached to the worm inside the shell. The larvae are released at an advanced stage of development and spend just a few hours as free-living organisms before attaching themselves to the nearest suitable surface, often the same seaweed as the parent. Description ''S. spirorbis'' secretes a very small, unridged, off-white, calcareous tube. This is about five millimetres in diameter and forms a flat, clockwise spiral coil as seen from above. The worm retreats into its tube when above water but under water can be seen to have green tentacles.John Barrett and C M Young, C ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, 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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
