Aporrhais Pespelecani
''Aporrhais pespelecani'', common name the "pelican's foot" (or more precisely "common pelican's foot" to distinguish it from congeners), is a species of sea snail, a marine gastropod mollusk in the family Aporrhaidae. Until the early 20th century the scientific name was usually written with a hyphen and spelled "pes-pelicani" Etymology and nomenclature The specific name ''pespelecani'' is Latin language, Latin, and means the same thing as the common name: "pelican's foot". This name is based on the shape of the three-pointed (or four-pointed) expanded outer lip of the adult shell, which resembles the webbed foot of a sea bird such as a pelican. The specific name is often spelled ''pespelicani'' by analogy with the modern spelling of the word "pelican", however this is incorrect. It was not the original spelling as used by Linnaeus, the original authority of the species, which he called ''Strombus Pes pelecani''. The rules of the ICZN state that the original spelling of a speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arrhoges Occidentalis
''Arrhoges occidentalis'', common name the American pelicanfoot, is a species of medium-sized sea snail, a marine gastropod mollusk in the family Aporrhaidae, the pelican's foot snails or pelican's foot shells. Morton (1956) considers ''Arrhoges occidentalis'' as the most primitive member of the family Aporrhaidae.Morton J. E. (1956). "The evolution of Perissodonta and Tylospira (Struthiolariidae)". '' Trans. R. Soc. N.Z.'' 83: 515–524. Distribution This species is distributed infralittoral, circalittoral and bathyal in the North West Atlantic Ocean and along the North American coast from Labrador and Massachusetts to off North Carolina. It lives on sand or mud at depths between 10 and 550 m. Off North Carolina it is usually found in deep water. Description The gray to yellowish-white shell is strong and has a high, pointed spire. Its length is between 4.1 and 6.4 cm (1I -2 inches). The shell has 8–10 well-rounded whorls, each of which shows many strong, curved ax ...

Stromboidea
The Stromboidea, originally named the Strombacea by Rafinesque in 1815, is a superfamily of medium-sized to very large sea snails in the clade Littorinimorpha.MolluscaBase eds. (2020). MolluscaBase. Stromboidea Rafinesque, 1815. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=14770 on 2020-05-24 Morphology Shell Stromboideans have medium to large shells, attaining a wide variety of lengths depending on the species (20–400 mm from the smallest aporrhaids to the largest strombids). A stromboidean shell has a medium (e.g. spider conchs, ''Lambis'' spp.) to high spire (e.g. tibias, ''Tibia'' spp.), and a thickened and frequently expanded outer lip (e.g. the queen conch, ''Lobatus gigas'', or the goliath conch, '' Lobatus goliath'') that may be ornamented by long spines (e.g. the spider conch, ''Lambis chiragra'', common pelican foot, ''Aporrhais'' spp.) or digitations (e.g. the millipede spider conch, ''Lambis m ...

Aporrhaidae is a family of sea snails commonly called the "pelican's foot snails." The taxonomy of the Gastropoda by Bouchet & Rocroi, 2005Bouchet P. & Rocroi J.-P. (Ed.); Frýda J., Hausdorf B., Ponder W., Valdes A. & Warén A. 2005. ''Classification and nomenclator of gastropod families''. Malacologia: International Journal of Malacology, 47(1-2). ConchBooks: Hackenheim, Germany. . ISSN 0076-2997. 397 pp. http://www.vliz.be/Vmdcdata/imis2/ref.php?refid=78278 categorizes Aporrhaidae as marine gastropod mollusks in the clade Littorinimorpha. Aporrhaids are commercially important, especially in traditional fisheries. Description Aporrhaids have a large lip with finger-like extensions, and a small operculum. They do not have movable eyes. Instead, their eyes are fixed at the base of each tentacle. The mollusk has one narrow foot, which renders its motion interrupted as the foot must raise the shell a tiny bit in each single movement, simultaneously pushing it forward. The motio ...

Rhaetian First Appearances
The Rhaetian is the latest age of the Triassic Period (in geochronology) or the uppermost stage of the Triassic System (in chronostratigraphy). It was preceded by the Norian and succeeded by the Hettangian (the lowermost stage or earliest age of the Jurassic). The base of the Rhaetian lacks a formal GSSP, though candidate sections include Steinbergkogel in Austria (since 2007) and Pignola-Abriola in Italy (since 2016). The end of the Rhaetian (and the base of the overlying Hettangian Stage) is more well-defined. According to the current ICS (International Commission on Stratigraphy) system, the Rhaetian ended ± 0.2 Ma (million years ago). In 2010, the base of the Rhaetian (i.e. the Norian-Rhaetian boundary) was voted to be defined based on the first appearance of '' Misikella posthernsteini'', a marine conodont. However, there is still much debate over the age of this boundary, as well as the evolution of ''M. posthernsteini''. The most comprehensive source of precise age da ...

Gastropod Genera
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.
