Carinariidae
Carinariidae, known by the common name "heteropods" like their relatives in the Pterotracheoidea, is a taxonomic family of swimming or floating sea snails, pelagic marine gastropod molluscs in the clade Littorinimorpha. Distribution The snails of this family occur worldwide in the pelagic zone of tropical to subtropical seas. floating or swimming by moving up and down the fin-shaped front part of their foot. Feeding habits They feed on jellyfish, larvae of other snails and on zooplankton. Anatomy The cylindrical body of these snails can be divided in three regions: the proboscis, the trunk and the tail region. The body is elongated and much longer than the reduced shell. But in ''Pterosoma'' the trunk is wider and is somewhat disc-shaped. The taenioglossan radula has seven teeth in each row: one central tooth, flanked on each side by one lateral and two marginal teeth. The central tooth has three central cusps and on each side a large process backing away from the center. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carinaria
''Carinaria'' is a genus of medium-sized floating sea snails, pelagic gastropod molluscs in the family Carinariidae. Anatomy The cylindrical and elongate body consists of three parts : a short proboscis, a well-developed trunk and tail region of variable size. The size of this tail goes from very small in ''Carinaria galea'' to very large in ''Carinaria cristata''. The well-developed swimming fin is located in both sexes at the back of the trunk and has at its back margin a small fin sucker. The right tentacle is small or vestigial. The cuticle is thick and gelatinous. The shells are known as “Venus slippers.” Species The World Register of Marine Species includes the following species within the genus ''Carinaria'': * ''Carinaria cithara'' Benson, 1835 – harp carinaria * '' Carinaria cristata'' (Linnaeus, 1767) – Indo-Pacific * ''Carinaria galea'' Benson, 1835 – helmet carinaria; Indo-Pacific * '' Carinaria japonica'' Okutani, 1955 – Japan, North Pacific * ''Carin ...

Pterotracheoidea
The Pterotracheoidea is, according to the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), a taxonomic superfamily of sea snails or sea slugs, marine gastropod molluscs in the clade Littorinimorpha. They are commonly called heteropods or sea elephants. Taxonomy This superfamily comprises four families (classification based on Newman (superfamily Carinarioidea, pp. 804–808. In: Beesley ''et al''., 1998), that is also used by the taxonomy of the Gastropoda by Bouchet & Rocroi (2005): * Family Pterotracheidae Rafinesque, 1814 * Family Atlantidae Rang, 1829 * † Family Bellerophinidae Destombes, 1984 * Family Carinariidae Blainville 1818 Habitat These holoplanktonic snails are found floating or swimming in tropical to subtropical open oceans and seas at a depth of maximum 200 to 300 m Anatomy These snails have adapted themselves to a pelagic living : * a transparent body and shell * the foot has evolved into a swimming fin that produces motion through undu ...

Cardiapoda
''Cardiapoda'' is a genus of very small floating sea snails or heteropods, pelagic gastropod molluscs or micromolluscs in the family Carinariidae. Both tentacles are of equal size and well-developed. The external layer of the body wall is thin. They are found worldwide in the pelagic zone of warm seas.

Littorinimorpha
Littorinimorpha is a large order of snails, gastropods, consisting primarily of sea snails ( marine species), but also including some freshwater snails ( aquatic species) and land snails (terrestrial species).Bouchet P. & Rocroi J.-P.

The order Littorinimorpha contains many gastropoda families that were formerly placed in the order Mesogastropoda, as introduced by J. Thiele in his work from 1921. Evidence for this group being monophyletic is scanty. In ... [...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 ...

Zooplankton
Zooplankton are the animal component of the planktonic community ("zoo" comes from the Greek word for ''animal''). Plankton are aquatic organisms that are unable to swim effectively against currents, and consequently drift or are carried along by currents in the ocean, or by currents in seas, lakes or rivers. Zooplankton can be contrasted with phytoplankton, which are the plant component of the plankton community ("phyto" comes from the Greek word for ''plant''). Zooplankton are heterotrophic (other-feeding), whereas phytoplankton are autotrophic (self-feeding). This means zooplankton cannot manufacture their own food but must eat other plants or animals instead — in particular they eat phytoplankton. Zooplankton are generally larger than phytoplankton, most are microscopic, but some (such as jellyfish) are macroscopic and can be seen with the naked eye. Many protozoans (single-celled protists that prey on other microscopic life) are zooplankton, including zooflagellates, fo ...

Brunonia (gastropod)
''Brunonia australis'', commonly known as the blue pincushion or native cornflower, is a perennial or annual herb that grows widely across Australia. It is found in woodlands, open forest and sand plains. In Cronquist's classification scheme it was the sole member of the monogeneric plant family Brunoniaceae. The APG II system moved it into Goodeniaceae, with which it shares the stylar pollen-cup, or indusium, a character confined to these taxa. ''Brunonia'' is unique among Goodeniaceae in its radially symmetric flowers, the superior ovary and the absence of endosperm in the seeds. The leaves are about 10 cm long and form a basal rosette. Flowering is usually in spring, with dense hemispherical clusters of numerous, small, bright blue flowers developing on several stems ( scapes) up to 50 cm in height. Taxonomy Specimens of ''Brunonia'' were first collected by Robert Brown during the 1801–02 voyage of HMS ''Investigator'' under the command of Matthew Flinders. T ...

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 ...

Alcide D'Orbigny
Alcide Charles Victor Marie Dessalines d'Orbigny (6 September 1802 – 30 June 1857) was a French naturalist who made major contributions in many areas, including zoology (including malacology), palaeontology, geology, archaeology and anthropology. D'Orbigny was born in Couëron ( Loire-Atlantique), the son of a ship's physician and amateur naturalist. The family moved to La Rochelle in 1820, where his interest in natural history was developed while studying the marine fauna and especially the microscopic creatures that he named "foraminiferans". In Paris he became a disciple of the geologist Pierre Louis Antoine Cordier (1777–1861) and Georges Cuvier. All his life, he would follow the theory of Cuvier and stay opposed to Lamarckism. South American era D'Orbigny travelled on a mission for the Paris Museum, in South America between 1826 and 1833. He visited Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, Argentina, Paraguay, and Brazil, and returned to France with an ...
