Eulima
''Eulima'' is a genus of small, ectoparasitic sea snails, marine gastropod mollusks in the family Eulimidae. ''Eulima'' is the type genus of the family Eulimidae. Description The genus appeared early in the Secondary and became abundant in forms during the Tertiary period. The shell is in the form of an elongated, towering spiral, which tapers to a fine point. The aperture is ovate and entire with the peristome incomplete behind. The outer lip is thick and even. "The imperforate shell is subulate, many-whorled, polished, and porcellanous Its spire is usually curved or twisted to one side, bearing on one side only, a series of varices forming ribs internally and marking the position of successive mouths. The apex is acute. The aperture is oval, entire, pointed above, rounded below. The lip is simple and a little thickened. The columellar margin is reflected. The operculum is corneous and pancispiral. Its nucleus is near the inner lip. The animal shows subulate tentacles, appro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eulimidae
Eulimidae is a family of very small parasitic sea snails, marine gastropod mollusks in the superfamily Vanikoroidea. Description These small parasitic snails live on (or in some cases in) the bodies of echinoderms such as sea cucumbers, sea urchins, sea stars, etc. All species lack a radula, in most cases possessing a proboscis which they extend into their host's body cavity in order to feed.

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 ...

Apex (mollusc)
In anatomy, an apex (adjectival form: apical) is part of the shell of a mollusk. The apex is the pointed tip (the oldest part) of the shell of a gastropod, scaphopod, or cephalopod. The apex is used in end-blown conches. Gastropods The word "apex" is most often used to mean the tip of the spire of the shell of a gastropod. The apex is the first-formed, and therefore the oldest, part of the shell. To be more precise, the apex would usually be where the tip of the embryonic shell or protoconch is situated, if that is still present in the adult shell (often it is lost or eroded away). Coiled gastropod shells The phrase apical whorls, or protoconch, means the whorls that constitute the embryonic shell at the apex of the shell, especially when this is clearly distinguishable from the later whorls of the shell, otherwise known as the teleoconch. Comparison of the apical part and the whole shell of ''Otukaia kiheiziebisu'': File:Calliostoma kiheiziebisu apex.png File:Calliostoma k ...

Paul Bartsch
Paul Bartsch (14 August 1871 Tuntschendorf, Silesia – 24 April 1960 McLean, Virginia) was an American malacologist and carcinologist. He was named the last of those belonging to the "Descriptive Age of Malacology". Early life Bartsch emigrated with his parents to the U.S.A in 1880, first to Missouri and then to Burlington, Iowa. As a child, he took up jobs in his spare time in several employments. He soon took an interest in nature, first by keeping a small menagerie at home, and during his high school years, collecting birds and preparing skins. He established a natural-history club in his home with a little museum and a workshop. By the time he went to the University of Iowa in 1893, he had collected 2,000 skins. Among his professors at the university were the University of Iowa were the geologist Samuel Calvin, botanists Thomas H. Macbride and Bohumil Shimek, and the zoologist Charles C. Nutting. He graduated from the university with a B.S. in 1896, and M.S. in 1899, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
