Bathybembix Bairdii 2
''Bathybembix'' is a genus of deep-water sea snails, marine gastropod molluscs in the family Eucyclidae. This genus was originally called ''Bembix'' by Robert B. Watson (, but as this was a junior homonym of ''Bembix'' Fabricius, 1775 ymenoptera it was declared invalid. It was renamed in 1893 by Crosse as ''Bathybembix'' Description The shell has a conical shape with a high spire. It is carinated and umbilicated. The base of the shell is inflated. The shell is covered with a thin, extremely persistent, smooth, fibrous epidermis, The epidermis swells up and becomes pustulated in water. The axis of the shell is perforated, and the columella is thin, reverted, and merely angulated in front. Species Species within the genus ''Bathybembix'' include: * ''Bathybembix abyssorum'' (Smith, 1891) * ''Bathybembix aeola'' (Watson, 1879) * ''Bathybembix bairdii'' ( Dall, 1889) * ''Bathybembix delicatula'' Dall, 1990 * ''Bathybembix drakei'' Dall, 1990 * ''Bathybembix galapagana'' ( Dall, ...

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 ...

Spire (mollusc)
A spire is a part of the coiled shell of molluscs. The spire consists of all of the whorls except for the body whorl. Each spire whorl represents a rotation of 360°. A spire is part of the shell of a snail, a gastropod mollusc, a gastropod shell, and also the whorls of the shell in ammonites, which are fossil shelled cephalopods. In textbook illustrations of gastropod shells, the tradition (with a few exceptions) is to show most shells with the spire uppermost on the page. The spire, when it is not damaged or eroded, includes the protoconch (also called the nuclear whorls or the larval shell), and most of the subsequent teleoconch whorls (also called the postnuclear whorls), which gradually increase in area as they are formed. Thus the spire in most gastropods is pointed, the tip being known as the "apex". The word "spire" is used, in an analogy to a church spire or rock spire, a high, thin, pinnacle. The "spire angle" is the angle, as seen from the apex, at which a spire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

William Healey Dall
William Healey Dall (August 21, 1845 – March 27, 1927) was an American naturalist, a prominent malacologist, and one of the earliest scientific explorers of interior Alaska. He described many mollusks of the Pacific Northwest of America, and was for many years America's preeminent authority on living and fossil mollusks. Dall also made substantial contributions to ornithology, zoology, physical and cultural anthropology, oceanography and paleontology. In addition he carried out meteorological observations in Alaska for the Smithsonian Institution. Biography Early life Dall was born in Boston, Massachusetts. His father Charles Henry Appleton Dall, (1816–86), a Unitarian minister, moved in 1855 to India as a missionary. His family however stayed in Massachusetts, where Dall's mother Caroline Wells Healey was a teacher, transcendentalist, reformer, and pioneer feminist. In 1862, Dall's father, on one of his few brief visits home, brought his son in contact with some natu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
