Vitrea Subrimata
''Vitrea subrimata'' is a small, air-breathing land snail species, a terrestrial pulmonate gastropod mollusk in the family Pristilomatidae.MolluscaBase eds. (2023). MolluscaBase. Vitrea subrimata (Reinhardt, 1871). Accessed through: World Register of Marine Species at: https://www.marinespecies.org/aphia.php?p=taxdetails&id=1002779 on 2023-06-14 ;Subspecies: * ''Vitrea subrimata litoralis'' (Clessin, 1877) Description The shell is small: 1.3-2.2 mm x 2.5–5 mm (diameter 2.6-2.7 mm at 3 whorls, 3.5-3.8 mm at 4 whorls) The shell is colourless and transparent. It contains 4-5 whorls. The width of the body whorl as seen from above is 1.2-1.7 times that of the penultimate whorl. The umbilicus is very narrow but is present (different from ''Vitrea diaphana''). The columellar margin is pointed and slightly protruding, covering the umbilicus very weakly. The shell is very variable, except for the characteristic form of the columellar margin at the umbilicus. The mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otto Wilhelm Hermann Reinhardt
Otto Wilhelm Hermann Reinhardt (1838 in Potsdam – 1924 in Berlin) was a German botanist and conchologist. He was a teacher at a trade school in Berlin. Reinhardt was a friend of Paul Friedrich August Ascherson and co-founder of the botanical society in Brandenburg province. He described the snails '' Vitrea subrimata'' in 1871 and '' Vallonia gracilicosta'' and '' Euconulus praticola'' in 1883. This last is the type species of Reinhardt's genus '' Euconulus''.

Umbilicus (mollusc)
The umbilicus of a coiled mollusc shell is the axially aligned, hollow cone-shaped space within its whorl (mollusc), whorls. The term ''umbilicus'' is often used in descriptions of gastropoda, gastropod shells, i.e. it is a feature present on the ventral (or under) side of many (but not all) snail shells, including some species of sea snails, land snails, and freshwater snails. The word is also applied to the depressed central area on the planispiral coiled shells of ''Nautilus'' species and fossil ammonites. (These are not gastropods, but shelled cephalopods.) In gastropods The spirally coiled whorls of gastropod shells frequently connect to each other by their inner sides, during the natural course of its formation. This results in a more or less solid central axial pillar, known as the columella (mollusc), columella. The more intimate the contact between the concave side of the whorls is, the more solid the columella becomes. On the other hand, if this connection is less inten ...

Great Asby Scar
Great Asby Scar is a Site of Special Scientific Interest (SSSI) and National Nature Reserve in Cumbria, UK. It is an area of limestone pavement, south of the village of Great Asby. History A "scar" is the local name for a limestone pavement—an area of limestone rock which has been eroded by an overlying ice sheet during the Last Glacial Maximum and then fissured by rain to form a flat rocky pattern which resembles man-made pavement. Many limestone pavements in the UK have been exploited by quarrying but this example is comparatively extensive and unspoilt. The overall area of pavement covers about and is called the Westmorland Scars. Great Asby Scar is in the centre of this region. Other scars include Orton Scar, Grange Scar, and Little Asby Scar. Site location and designation It is in the Orton Fells in the district of Westmorland and Furness, near the village of Great Asby. Great Asby Scar was first designated as a Site of Special Scientific Interest in 1969 and the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Slovak Academy Of Sciences
The Slovak Academy of Sciences (, or SAV) is the main scientific and research institution in Slovakia fostering basic and strategic basic research. It was founded in 1942, closed after World War II, and then reestablished in 1953. Its primary mission is to acquire new knowledge of nature, society and technology, specifically targeted at ensuring scientific basis for the advancement in Slovakia. It comprises 58 scientific institutes and 13 ancillary institutions. The SAV edits 44 scientific and scholarly journals and 100–120 monographs per annum. Moreover, 41 scientific and scholarly societies, which associate scientists and scholars from various disciplines, are affiliated with SAV. History The commencement of modern science in the 16th and 17th centuries resulted in the establishment of new institutions that supplemented classical universities and created a broader forum for fostering science communication.

AnimalBase
AnimalBase is a project brought to life in 2004 and is maintained by the University of Göttingen, Germany. The goal of the AnimalBase project is to digitize early zoological literature, provide copyright-free open access to zoological works, and provide manually verified lists of names of zoological genera and species as a free resource for the public. AnimalBase contributed to opening up the classical taxonomic literature, which is considered as useful because access to early literature (especially for the late 18th century) can be difficult for researchers who need the old sources for their taxonomic research. AnimalBase data are public domain. The public use of AnimalBase data is not restricted or conditioned.AnimalBase Project Group, 2005-2010. AnimalBase. Early zoological literature online. World wide web electronic publication http://www.animalbase.uni-goettingen.de accessed 30 July 2010. AnimalBase covers all zoological disciplines. In the field of biodiversity informatics ...

Body Whorl
The body whorl is part of the morphology (biology), morphology of the gastropod shell, shell in those gastropod mollusks that possess a coiled shell. The term is also sometimes used in a similar way to describe the shell of a cephalopod mollusk. In gastropods In gastropods, the body whorl, or last whorl, is the most recently formed and largest Whorl (mollusc), whorl (or revolution) of a spiral or Helix, helical Gastropod shell, shell, terminating in the Aperture (mollusc), aperture. It is called the "body whorl" because most of the body of the soft parts of the animal fits into this whorl. The proportional size of the body whorl in gastropod shells differs greatly according to the actual shell morphology. For shells in which the rate of whorl expansion of each revolution around the axis is very high, the aperture and the body whorl are large, and the shell tends to be low Spire (mollusc), spired. The shell of the abalone is a good example of this kind of shell. The opposite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Snail
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial molluscs, terrestrial gastropod mollusks that have gastropod shell, shells (those without shells are known as slugs). However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water. Land snails are a Polyphyly, polyphyletic group comprising at least ten independent evolutionary transitions to terrestrial life (the last common ancestor of all gastropods was marine). The majority of land snails are pulmonates that have a lung and breathe air. Most of the non-pulmonate land snails belong to lineages in the Caenogastropoda, and tend to have a gill and an operculum (gastropod), operculum. The largest clade of non-pulmonate land snails is the Cyclophoroidea, with more than 7,0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whorl (mollusc)
A whorl is a single, complete 360° revolution or turn in the spiral or whorled growth of a mollusc shell. A spiral configuration of the shell is found in numerous gastropods, but it is also found in shelled cephalopods including ''Nautilus'', ''Spirula'' and the large extinct subclass of cephalopods known as the ammonites. A spiral shell can be visualized as consisting of a long Cone (geometry), conical tube, the growth of which is coiled into an overall Helix, helical or planispiral shape, for reasons of both strength and compactness. The number of whorls which exist in an adult shell of a particular species depends on mathematical factors in the geometric growth, as described in D'Arcy Wentworth Thompson's classic 1917 book ''On Growth and Form'', and by David Raup. The main factor is how rapidly the conical tube expands (or flares-out) over time. When the rate of expansion is low, such that each subsequent whorl is not that much wider than the previous one, then the adult s ...
