George Washington Tryon
George Washington Tryon Jr. (20 May 1838 – 5 February 1888) was an American malacologist who worked at the Academy of Natural Sciences in Philadelphia. Biography George Washington Tryon was the son of Edward K. Tryon and Adeline Savidt. In 1853 he attended the Friends Central School in Philadelphia. In 1859, Tryon became a member of the Academy of Natural Sciences of Philadelphia. He was largely responsible for the construction of new buildings for the Academy, especially, in 1866, a section for malacology. In 1869 he became the conservator in this malacological section. In 1865, together with a group of American malacologists, he founded (and financed) the American Journal of Conchology. This ended in 1872. In 1879 he started the ''Manual of Conchology; structural and systematic; with illustrations of the species'', volume 1, series 1. When he died, nine volumes of the first series had been published. From 1887 until 1888, his assistant was Henry Augustus Pilsbry. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malacology
Malacology is the branch of invertebrate zoology that deals with the study of the Mollusca (mollusks or molluscs), the second-largest phylum of animals in terms of described species after the arthropods. Mollusks include snails and slugs, clams, and cephalopods, along with numerous other kinds, many of which have shells. One division of malacology, conchology, is devoted to the study of mollusk shells. Malacology derives . Fields within malacological research include taxonomy, ecology and evolution. Applied malacology studies medical, veterinary, and agricultural applications; for example, mollusks as vectors of disease, as in schistosomiasis. Archaeology employs malacology to understand the evolution of the climate, the biota of the area, and the usage of the site. In 1681, Filippo Bonanni wrote the first book ever published that was solely about seashells, the shells of marine mollusks. The book was entitled: In 1868, the German Malacological Society was founded. Zoologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fasciolariidae
The Fasciolariidae, common name the "tulip snails and spindle snails", are a family (biology), family of small to large sea snails, marine (ocean), marine gastropod mollusks in the superfamily Buccinoidea. The family Fasciolariidae probably appeared about 110 million years ago during the Cretaceous Distribution The recent species inhabit tropical to temperate waters. Description The shells are usually reddish in color and have a moderate to large size, reaching a height between 1.0 and 60 cm. The shells are spindle-shaped and biconic. The Spire (mollusc), spire is elongated. The siphonal canal is well developed and is long to moderately long. The columella varies between a smooth appearance and showing spiral folds. The horny Operculum (gastropod), operculum has an oval shape. Their radula is characteristic with narrow central teeth with three cusps. The wide lateral teeth show numerous ctenoid (= comblike) cusps. Snails in the family Fasciolariidae are carnivorou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strombidae
Strombidae, commonly known as the true conchs, is a taxonomic family of medium-sized to very large sea snails in the superfamily Stromboidea, and the Epifamily Neostromboidae. The term true conchs, being a common name, does not have an exact meaning. It may refer generally to any of the Strombidae but sometimes is used more specifically to include only ''Strombus'' and ''Lambis''. The family currently includes 26 extant, and 10 extinct genera. Distribution Strombid gastropods live mainly in tropical and subtropical waters. These animals are widespread in the Indo-West Pacific, where most species and genera occur. Nearly 40 of the living species that used to belong to the genus ''Strombus'' can be found in the Indo-Pacific region.Abbott, R.T. (1960). "The genus Strombus in the Indo-Pacific". ''Indo-Pacific Mollusca'' 1(2): 33-144 They also occur in the eastern Pacific and Western Atlantic, and a single species can be found on the African Atlantic coast. Six species of strombid ...

Pleurotomidae
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 Turr ...

Conidae
Conidae, with the current common name of "cone snails", is a taxonomic family (previously subfamily) of predatory sea snails, marine gastropod molluscs in the superfamily Conoidea. The 2014 classification of the superfamily Conoidea, groups only cone snails in the family Conidae. Some previous classifications grouped the cone snails in a subfamily, Coninae. As of March 2015 Conidae contained over 800 recognized species. Working in 18th-century Europe, Carl Linnaeus knew of only 30 species that are still considered valid. The snails within this family are sophisticated predatory animals. They hunt and immobilize prey using a modified radular tooth along with a venom gland containing neurotoxins; the tooth is launched out of the snail's mouth in a harpoon-like action. Because all cone snails are venomous and capable of "stinging" humans, live ones should be handled with great care or preferably not at all.

Marginellidae
Marginellidae, or the margin shells, are a Taxonomy (biology), taxonomic family (biology), family of small, often colorful, sea snails, Marine (ocean), marine gastropod molluscs in the clade Neogastropoda. Taxonomy The higher classification of the family Marginellidae has long been in a state of confusion. Many popular works still treat all members of this family under the single genus ''Marginella'', basing them primarily on superficial similarities of the shell. The confusion over the classification stems from the fact that the earlier classifications were based rather crudely on shell characters. Although many good differential shell characters do exist within this group, those characters were generally misinterpreted or not recognized as significant. Such information as did exist on the radulae and the external anatomy of the living animals was widely scattered in the scientific literature, and internal anatomical descriptions were not available until fairly recently.

Mitridae
Mitridae, known as mitre shells, are a taxonomic family of sea snails, widely distributed marine gastropod molluscs in the clade Mitroidea.MolluscaBase (2018). Mitridae Swainson, 1831. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=23073 on 2018-03-04 Both the Latin name and the common name are taken from the item of ecclesiastical headgear, the mitre or miter, used in reference to the shape of the shells. The dentition of radula in the Mitroidea is rachiglossate, with well-developed central and lateral teeth, both comb-like. Members of this family are predators.
