Gemmula
''Gemmula'', common name the gem turrids, is a genus of sea snails, marine gastropod mollusks in the family Turridae, the turrids. These snails have been recorded as fossils from the Paleocene to the Quaternary (from 66.043 to 0.012 Ma). Fossils have been found all over the world. This genus is still regarded as paraphyletic and should be revised. A high number of undescribed species are estimated to belong to ''Gemmula''. Since independent “Gemmula-like” lineages are distributed all over the turrid tree, a revision of ''Gemmula'' would entail again a complete revision of the family Turridae. They are venomous with disulfide-rich polypeptides in their venom ducts. These bioactive peptides are likely to become a resource for novel pharmacologically active compounds Habitat and feeding habits The snails in this genus occur mostly in deeper tropical waters at depths between 50 and 500m. Because of these deep habitats, little is known about their feeding habits. Taxonomy T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turridae
Turridae is a taxonomic family name for a number of predatory sea snails, marine gastropod mollusks in the superfamily Conoidea. MolluscaBase (2018). Turridae H. Adams & A. Adams, 1853 (1838). Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=152 on 2018-07-22 The family name Turridae was originally given to a very large group of several thousand sea snail species that were thought to be closely related. The family was described with about 700 genus-group taxa and an estimated 10,000 recent and fossil species. However, that original grouping was discovered to be polyphyletic. In recent years, the family Turridae has been much reduced in size, because a number of other families were created to contain the monophyletic lineages that had previously been thought to belong in the same family. The common name ''turrids'' is still used informally to refer to the polyphyletic group. Distribution Species in the family ...

Lophiotoma
''Lophiotoma'' is a genus of sea snails, marine gastropod mollusks in the family Turridae, the turrids. Fossils of this genus have been found in many places in the Indo-Pacific, but also going as far back as 61.7 Ma in paleocene strata of Alabama, USA. Original description Although having the small smooth embryo of a single whorl, polished surface and obsolete lines of growth, characterizing ''Pleurotoma'' (now ''Turris''), this genus may be recognized at once by the relatively shorter and stouter form as a rule, less elongate and straighter beak, which is strongly tapering in certain large forms like line ''unedo'', finer, more acutely elevated and less close-set spiral carinae, with a usually distinct and even, finely lineolate concavity from the peripheral carina to the suture or subsutural collar, the latter being generally present and by the deep anal sinus formed centrally on, and not behind, the peripheral carina, the latter being more strongly elevated and usually subdu ...

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 ...

Polystira
''Polystira'' is a genus of sea snails, marine gastropod mollusks in the family Turridae, the turrids. Taxonomy Paul Bartsch (1934) states the genus ''Polystira'' was created by W. P. Woodring in 1928 for certain large West Indian turrids. He named the largest of the recent species, generally known as ''Pleurotoma albida'' Perry, as type. Unfortunately, the mollusk so designated is not ''Pleurotoma albida'' Perry, which Perry states " is frequently found at New Zealand and Lord Howe Island." Perry's figure 4, plate 32, of this species does not agree with the West Indian material. It clearly resembles certain shells from North Australia in the collection of the National Museum. The name is, therefore, not applicable to the West Indian shell, which will have to carry the next available designation. Lamarck Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; ), was a French naturalist, biologist, ac ...

Pinguigemmula
''Cryptogemma'' is a genus of sea snails, marine gastropod mollusks in the family Turridae, the turrids. Distribution These are deep-sea species with a wide geographic distribution. Species According to Zaccharias ''et al.'' (2020) this genus should only include: * '' Cryptogemma aethiopica'' (Thiele, 1925) * '' Cryptogemma periscelida'' (Dall, 1889) * '' Cryptogemma phymatias'' (Watson, 1886) * '' Cryptogemma powelli'' Zaharias, Kantor, Fedosov, Criscione, Hallan, Kano, Bardin & Puillandre, 2020 * '' Cryptogemma praesignis'' (Smith, 1895) * '' Cryptogemma tessellata'' (Powell, 1964) * '' Cryptogemma timorensis'' (Tesch, 1915) * ''Cryptogemma unilineata'' (Powell, 1964). The others should be excluded from this genus because the lack key characters such as the narrow fusiform shell and the well-marked peripheral anal sinus. They show closer resemblances to other conoidean families (such as Horaiclavidae) than to Turridae. Species within the genus ''Cryptogemma'' include (acco ...

Gemmuloborsonia
''Gemmuloborsonia'' is a genus of sea snails, marine gastropod mollusks in the family (biology), family Turridae. Description This genus was previously provisionally included in the family Clavatulidae as the characters of the shell and the radula of this genus resemble more the characters of this family than those of the family Horaiclavidae. However, it differs from the other genera in this family by its weak columellar pleats and the multispiral protoconch in the Recent specie. However the extinct species type has a paucispiral, globose and almost smooth protoconch. This must then be considered an apomorphic character state. The fusiform shell is moderately small. The Spire (mollusc), spire is relatively high and the base is contracted. The spire shows a peripheral cord with gemmules. The anal sinus is deep and its crest reaches the peripheral cord. The distinct columellar pleat is blunt. Distribution Originally only known as a fossil from the Upper Miocene-Lower Pleistocene ...
