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 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'' include: * '' Callogaza colmani'' Hickman, 2012 * ''Callogaza frederici'' (E. A.

Gaza (gastropod)
''Gaza'' is a genus of sea snails, marine (ocean), marine gastropod mollusks in the family (biology), family Margaritidae. Description An examination of the soft parts of a species of the genus Gaza, by William Healey Dall, Dall showed the Operculum (gastropod), operculum to be very thin, light brown, and with about seven Whorl (mollusc), 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 expans ...

Gaza Daedala
''Gaza daedala'' is a species of sea snail, a marine gastropod mollusc in the family Margaritidae.Rosenberg, G. (2012). ''Gaza daedala'' Watson, 1879. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=594177 on 2012-12-03 Distribution This marine species occurs in the Pacific Ocean off Fiji at a depth of 1100 m.

It is translucent, horny, nacreous in its whole texture, and iridescent on the surface. It has a slightly reverted and narrowly thickened lip and a thin edged twisted columella, the point of which runs out into a bluntly mucronated angle.

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 language, 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 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 Valdivia Expedition, 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 thr ...

Family (biology)
Family (, : ) 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". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Sea Snail
Sea snails are slow-moving marine (ocean), marine gastropod Mollusca, molluscs, usually with visible external shells, such as whelk or abalone. They share the Taxonomic classification, taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible Gastropod shell, 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 Neritidae, 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 (gastropod), Truncatella'') are sometimes considered to be sea snails and sometimes listed as land snails. Anatomy Sea snails are a very large and diverse group of animals. 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 w ...
