Calliotropis Naybandensis
''Calliotropis'' is a genus of sea snails, marine gastropod mollusks in the family Eucyclidae. Taxonomy According to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005) the genus ''Calliotropis'' is placed in the subfamily Calliotropinae within the family Chilodontidae. New insights into the taxonomy of the Seguenzioidea were provided by Kano (2007).Kano Y. (2007). "Vetigastropod phylogeny and a new concept of Seguenzioidea: independent evolution of copulatory organs in the deep-sea habitats". '' Zoologica Scripta'' 37(1): 1–21. Description The size of the shell of species in this genus is small to moderate. The iridescent shell is thin and contains a conspicuous umbilicus. Its sculpture shows spiral rows with many tubercles. The shells resemble '' Solariella'', but differ in the radula, which is longer, with a larger number of uncini. The teeth of the median part are less denticulated. Species Species within the genus ''Calliotropis'' include: *''Calliotropis ...

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Umbilicus (mollusc)
The umbilicus of a shell is the axially aligned, hollow cone-shaped space within the whorls of a coiled mollusc shell. The term umbilicus is often used in descriptions of 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. 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 intense, a hollow space inside the whorls may re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Paul Henri Fischer
Paul Henri Fischer (also spelled Paul-Henri Fischer), (7 July 1835 Paris – 29 November 1893) was a French physician, zoologist and paleontologist. He is generally known as Paul Fischer. Biography He studied science and medicine, securing doctorates in both, and became assistant in paleontology at the National Museum of Natural History in Paris. He was made assistant naturalist there in 1872. Beginning in 1856, he was joint editor, with A. C. Bernardi to start with, of the ''Journal de Conchyliologie''. He served several terms as president of the Société Géologique de France Lactalis is a French multinational dairy products corporation, owned by the Besnier family and based in Laval, Mayenne, France.

Philippe Dautzenberg
Philippe Dautzenberg (20 December 1849, in Ixelles, Brussels – 9 May 1935, in Paris) was a Belgian malacologist, a biologist who specializes in the branch of invertebrate zoology that deals with mollusks. He was an amateur and autodidact, who was actually the owner of a carpet and soft furnishings factory. He was also a devoted family man with 12 children. He assembled, thanks to his many connections all over the world, a large part of the shell collection of the Royal Belgian Institute of Natural Sciences, which consists of 9,000,000 specimens and is one of the three largest shell collections in the world. He was a participant in the scientific surveys of Prince Albert I of Monaco and the author of 210 published works (between 1881 and 1937 (post mortem) ) in the field of malacology. He described 1895 new taxa. He collected shells from an early age, resulting in his personal collection of about 4.5 million specimens, relating to 33,000 Recent taxa and 7,000 fossil species. H ...

Robert Boog Watson
Robert Boog Watson FRSE (26 September 1823 – 23 June 1910) was a Scottish malacologist and minister of the Free Church of Scotland best known as the author of the report on the Scaphopoda and Gastropoda collected during the H.M.S. ''Challenger'' expedition to survey the world's oceans from 1873 to 1876. Watson also described various Opisthobranchia from Madeira. Life He was born in Burntisland in Fife, the son of the Rev Dr Charles Watson DD (1794-1866) of Burntisland and Isabella Boog.

Calliotropis Aeglees
''Calliotropis aeglees'' is a species of sea snail, a marine gastropod mollusk in the family Eucyclidae. Description The shell grows to a length of 7.6 mm. The high shell has a broadly conical shape. The color of the shell is pure white when weathered, but apparently slightly brownish when fresh, with a pearly nacre below the thin calcareous surface layer. The shell has a very large umbilicus. It is carinated and ornamented with rows of tubercles. There is a row of small round pointed tubercles a little below the suture. The carina is double, formed by two rather remote tubercled threads, the lower of which runs to the outer lip. Below this one is a broadish furrow and slightly beaded thread, which toward the mouth projects so as to become a third carina. The center of the base has another slightly beaded thread. There is another formed of remote rounded tubercles, defining the umbilicus, within which is a very slight furrow and an ill-defined ridge. The apical whorls are ...
