Callogaza
''Callogaza'' is a genus of sea snails, marine gastropod mollusks in the family Margaritidae. Description The shells of the species in this genus are thin-walled and almost transparent. Because of this, they are iridescent. The outer lip is deflected. A flat callus of the inner lip covers completely or only in part the wide umbilicus (but only in fully grown species). These features form a synapomorphy with the genus '' Gaza''. The sculpture Sculpture is the branch of the visual arts that operates in three dimensions. Sculpture is the three-dimensional art work which is physically presented in the dimensions of height, width and depth. It is one of the plastic arts. Durable ... of ''Callogaza'' has stronger spiral and axial lines, in contrast with the almost uniform sculpture of ''Gaza''. ''Calogaza'' possesses strong, elevated spiral cords in the upper part of each whorl. These are colored with brown spots. Species Species within the genus ''Callogaza'' inclu ...

Trochoidea (superfamily)
Trochoidea is a superfamily of small to very large vetigastropod sea snails with gills and an operculum.Gofas, S. (2013). Trochoidea. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=156489 on 2013-06-29 Species within this superfamily have nacre as the inner shell layer. The families within this superfamily include the Trochidae, the top snails. This superfamily is the largest vetigastropodan superfamily, containing more than 2,000 species. This taxon is ''not'' the same as a pulmonate land snail genus which is spelled the same way: ''Trochoidea'' (genus). Taxonomy 2005 taxonomy This superfamily consisted of nine following families (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005): * Trochidae Rafinesque, 1815 * Calliostomatidae Thiele, 1924 (1847) * † Elasmonematidae Knight, 1956 * † Eucochlidae Bandel, 2002 * † Microdomatidae Wenz, 1938 * † Proconulidae Cox, 1960 * Solarie ...

Gaza (gastropod)
''Gaza'' is a genus of sea snails, marine gastropod mollusks in the family Margaritidae. Description An examination of the soft parts of a species of the genus Gaza, by Dall showed the operculum to be very thin, light brown, and with about seven whorls. The animal was of a whitish color without any spots or markings, and with very large black eyes set on a good-sized peduncle closely adjacent to and behind the tentacles. There is a single narrow gill in the usual position. The tentacles are long, large, and rather slender. The foot is short, broad, and bluntly rounded in front, behind almost truncate. In fact the contracted specimen looked almost as if there was a broad posterior indentation in the middle line. The muzzle is long, narrow, subcylindrical above and transversely expanded at its distal end, which is semi-lunar with a densely papillose surface and fringed edges. This expansion is nearly three times as wide as the stem of the muzzle. The epipodium (the lateral groov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbinidae
Turbinidae, the turban snails, are a family of small to large marine gastropod molluscs in the superfamily Trochoidea.Bouchet, P. (2014). Turbinidae Rafinesque, 1815. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=503 on 2014-07-28 Description Turbinidae have a strong, thick calcareous operculum readily distinguishing them from the somewhat similar Trochidae or top snails, which have a corneous operculum. This strong operculum serves as a passive defensive structure against predators that try to enter by way of the aperture or that would break the shell at the outer lip. These operculum are rounded ovals that are flat with a swirl design on one side and domed on the other. They are known as Pacific cat's eye or Shiva eye shells or mermaid money, and are used for decorative purposes. Etymology The common name ''turban snail'' presumably refers to the shell's similarity in appearance to a turban. However, the scient ...

Johannes Thiele (zoologist)
Karl Hermann Johannes Thiele (1 October 1860 – 5 August 1935) was a German zoologist specialized in malacology. Thiele was born in Goldap, East Prussia. His ''Handbuch der systematischen Weichtierkunde'' (English edition published by the Smithsonian under the title ''Handbook of Systematic Malacology'') is a standard work. From 1904 until his retirement in 1925 he was the curator of the malacological collection at the Museum für Naturkunde (Museum of Natural History) in Berlin. Thiele described more than 1.500 new species of molluscs; until today their types are deposited with the Museum of Natural History in Berlin. Especially important are his works on the Mollusca of the First German Antarctica Expedition and of the German Deep Sea Expedition aboard the vessel Valdivia. Thiele's classification of Gastropoda has been in use up to the past decade. It modified an earlier concept of Henri Milne-Edwards (1848) with three subclasses: Prosobranchia, Opisthobranchia and Pulmonata. ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Sea Snail
Sea snail is a common name for slow-moving marine gastropod molluscs, usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell. Definition Determining whether some gastropods should be called sea snails is not always easy. Some species that live in brackish water (such as certain neritids) can be listed as either freshwater snails or marine snails, and some species that live at or just above the high tide level (for example species in the genus '' Truncatella'') are sometimes considered to be sea snails and sometimes listed as land snails. Anatomy Sea snails are a very large group of animals and a very diverse one. Most snails that live in salt water respire using a gill or gills; a few species, though, have a lung, are intertidal, and are active only at low tide when they can move around in the air. These air-breathing species includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine (ocean)
The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the world ocean is conventionally divided."Ocean." ''Merriam-Webster.com Dictionary'', Merriam-Webster, |
