Calyptraeoidea
The Calyptraeidae are a family of small to medium-sized marine prosobranch gastropods. MolluscaBase. Calyptraeidae Lamarck, 1809. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=141 on 2019-11-04 This family includes the slipper snails (''Crepidula'' species), the Chinese hat snails, (''Calyptraea'' species), and the cup-and-saucer snails (''Crucibulum'' species) among others. The Calyptraeidae are the only family in the superfamily Calyptraeoidea. This family has no subfamilies according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005. ''Crepidula fornicata'' was brought to Europe on imported American oysters in the late 19th century and is now considered a significant pest in European oyster beds. Description Internally, the shell is distinguished by a shelf-like, cup-like, or half-cup-like structure used for muscle attachment. Some calyptraeids have shells that externally resemble those of limpet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bostrycapulus
''Bostrycapulus'', commonly known as the spiny slipper snails, is a genus of sea snails, marine gastropod mollusks in the family Calyptraeidae, the slipper snails, cup-and-saucer snails and hat snails. Before 2005, the snails in this genus were all thought to belong to one species, which was known as ''Crepidula aculeata'', the spiny slipper snail.Collin R. (2005). "Development, phylogeny, and taxonomy of'' Bostrycapulus'' (Caenogastropoda: Calyptraeidae), an ancient cryptic radiation". ''Zoological Journal of the Linnean Society'' 144(1): 75-101. . However, morphological and DNA sequence data show that the spiny slipper snails are a monophyletic group that is more closely related to ''Crepipatella'' than it is to ''Crepidula''. Taxonomy Taxonomic history All of the species within the genus'' Bostrycapulus'' were previously assigned to a single species, ''Crepidula aculeata''. However, molecular phylogenetic and anatomical work have shown them to be a separate monophyleti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal ''Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

Crepipatella
''Crepipatella'' is a genus of sea snails, marine gastropod mollusks in the family Calyptraeidae, the slipper snails and cup-and-saucer snails. MolluscaBase eds. (2020). MolluscaBase. Crepipatella Lesson, 1831. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=234136 on 2020-09-26 The snails in this genus were formerly all thought to belong to the genus ''Crepidula'', but DNA sequence data show that they are a separate genus. A recent revision of the South American species has led to some significant taxonomic changes, as well as the addition of a new species - Crepipatella occulta Veliz et al. 2012. Species Species within the genus ''Crepipatella'' include: * ''Crepipatella capensis'' (Quoy and Gaimard, 1832–33) This species is known from the upwelling area of South Africa around Cape Town. These animals have direct development where embryonic nutrition is provided by nurse embryos (termed adelphophagy). ''C. c ...

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, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with natural laws. Lamarck fought in the Seven Years' War against Prussia, and was awarded a commission for bravery on the battlefield. Posted to Monaco, Lamarck became interested in natural history and resolved to study medicine. Packard (1901), p. 15. He retired from the army after being injured in 1766, and returned to his medical studies. Lamarck developed a particular interest in botany, and later, after he published the three-volume work ''Flore françoise'' (1778), he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the Jardin des Plantes and was appointed to the Chair of Botany in 1788. When the French National Assembly founded the Muséum ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...
