Prionovolvinae
Ovulidae, common names the ovulids, cowry allies or false cowries, is a family of small to large predatory or parasitic sea snails, marine gastropod molluscs in the superfamily Cypraeoidea, the cowries and the cowry allies. MolluscaBase eds. (2020). MolluscaBase. Ovulidae J. Fleming, 1822. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=1747 on 2020-05-25 Distribution The ovulids are a widespread family, occurring mostly in tropical and subtropical waters, with most species in the Indo-West Pacific region. But a few species live in temperate waters. Habitat Ovulids are carnivorous molluscs that feed on polyps and tissues of Anthozoa (as do the genera ''Cyphoma'' and ''Pseudocyphoma''). They live on, and eat, soft corals and sea fans, and they are usually regarded as ectoparasites of these sessile colonial organisms, to which they are anchored by a long and narrow foot.

Ovulinae
The subfamily Ovulinae, common name the ovulines, is a highly specialized, extant group of sea snails in the family Ovulidae. These are predatory or parasitic sea snails, marine gastropod mollusks within the superfamily Cypraeoidea. Species in this subfamily are sometimes referred to as cowries (singular: cowry or cowrie), although this name is commonly used for any member of the superfamily Cypraeoidea. Description Ovulinae typically have either an ovate (egg-shaped), lanceolate (lance-shaped) or pyriform (pear-shaped) shell. The spire is not prominent, and the funiculum is absent. The anal canal is twisted anteriorly. The extremities are usually short and the outer lip of the aperture has well-developed teeth. The mantle usually completely covers the shell in life. The mantle is typically brightly colored, while the shell is often white, although in some cases the shell is pink or even red. This can easily be seen in photographs of the snails. Habitat Ovulines live parasi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyphoma Gibbosum
The flamingo tongue snail (''Cyphoma gibbosum'') is a species of small but brightly colored sea snail, a marine gastropod mollusk in the family Ovulidae, the cowry allies. Distribution This is the most common of several species in the genus ''Cyphoma'', which lives in the tropical waters of the western Atlantic Ocean from North Carolina to northern coast of Brazil, including off Bermuda, in the Caribbean Sea and the Gulf of Mexico, and off the Lesser Antilles . Three species of ''Cyphoma'', known as ''Cyphoma gibbosum'', ''Cyphoma signatum'' and ''Cyphoma mcgintyi'' have been found to be genetically similar even though their phenotypes suggest otherwise. The species of ''Cyphoma signatum'' and ''Cyphoma mcgintyi'' can be distinguished from their different patterns; whether having a fingertip pattern or brown dots. However, if these two species were being distinguished based on their morphological features, it would be difficult to differentiate them. The genotype of these sp ...

Ectoparasites
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: an endoparasite lives inside the host's body; a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franz Alfred Schilder
Franz Xaver Alfred Johann Schilder (born 13 April 1896 in Královské Vinohrady, now a district of Prague, died 11 August 1970 in Halle ) was an Austrian-born German biologist, taxonomist, malacologist and honorary professor of animal geography. Life Franz Alfred Schilder was born on 13 April 1896 in Prague suburbs. In 1908, Schilder moved to Vienna. Having graduated from school in 1914, he studied medicine, but the next year his studies were interrupted by war. After the war, he continued studies in ethnography, geography and paleontology. In 1921, he became a Doctor of Philosophy. In 1922, Schilder emigrated to Germany. In Berlin he started attending the Entomological Museum. Around this time Schilder married Maria Heitrich, a German chemist. In 1925, Schilder already was a recognized scientist at Naumburg/Saale in the state institute for research on '' Phylloxera'', remaining there until 1947. In 1945, Schilder became a professor of zoology at the University of Halle-sur- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Edward Gray
John Edward Gray, FRS (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoologica ... [...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 ...

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While ... Sources {{biology-stub ...

Cowries
Cowrie or cowry () is the common name for a group of small to large sea snails, marine gastropod mollusks in the family Cypraeidae, the cowries. The term ''porcelain'' derives from the old Italian term for the cowrie shell (''porcellana'') due to their similar appearance. Shells of certain species have historically been used as currency in several parts of the world, as well as being used, in the past and present, very extensively in jewelry, and for other decorative and ceremonial purposes. The cowrie was the shell most widely used worldwide as shell money. It is most abundant in the Indian Ocean, and was collected in the Maldive Islands, in Sri Lanka, along the Indian Malabar coast, in Borneo and on other East Indian islands, in Maluku in the Pacific, and in various parts of the African coast from Ras Hafun to Mozambique. Cowrie shell money was important in the trade networks of Africa, South Asia, and East Asia. In the United States and Mexico, cowrie species inhabit the ...

Spire (mollusc)
A spire is a part of the coiled shell of molluscs. The spire consists of all of the whorls except for the body whorl. Each spire whorl represents a rotation of 360°. A spire is part of the shell of a snail, a gastropod mollusc, a gastropod shell, and also the whorls of the shell in ammonites, which are fossil shelled cephalopods. In textbook illustrations of gastropod shells, the tradition (with a few exceptions) is to show most shells with the spire uppermost on the page. The spire, when it is not damaged or eroded, includes the protoconch (also called the nuclear whorls or the larval shell), and most of the subsequent teleoconch whorls (also called the postnuclear whorls), which gradually increase in area as they are formed. Thus the spire in most gastropods is pointed, the tip being known as the "apex". The word "spire" is used, in an analogy to a church spire or rock spire, a high, thin, pinnacle. The "spire angle" is the angle, as seen from the apex, at which a spire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aperture (mollusc)
The aperture is an opening in certain kinds of mollusc shells: it is the main opening of the shell, where the head-foot part of the body of the animal emerges for locomotion, feeding, etc. The term ''aperture'' is used for the main opening in gastropod shells, scaphopod shells, and also for ''Nautilus'' and ammonite shells. The word is not used to describe bivalve shells, where a natural opening between the two shell valves in the closed position is usually called a ''gape''. Scaphopod shells are tubular, and thus they have two openings: a main anterior aperture and a smaller posterior aperture. As well as the aperture, some gastropod shells have additional openings in their shells for respiration; this is the case in some Fissurellidae (keyhole limpets) where the central smaller opening at the apex of the shell is called an orifice, and in the Haliotidae (abalones) where the row of respiratory openings in the shell are also called orifices.
