Cypraeidae
Cypraeidae, common name, commonly named the cowries ( cowry or cowrie), is a Taxonomy (biology), taxonomic family (biology), family of small to large sea snails. These are marine (ocean), marine gastropod mollusks in the superfamily Cypraeoidea, the cowries and cowry allies. Shell description Cypraeidae have adult shells which are very rounded, almost like an egg; they do not look like a typical gastropod shell. Their glossy, polished, ovate-shaped shells have beautiful patterns in a variety of colors. These patterns, combined with minor variations in shell form, have led some conchologists to recognize 60 genera and hundreds of species and subspecies. In virtually all of the species in the family Cypraeidae, the shells are extremely smooth and shiny. This is because in the living animal, the shell is nearly always fully covered with the mantle (mollusc), mantle. The upper surface is typically convex, while the ventral side is flattened. Typically, no spire (mollusc), spire is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cypraeoidea
Cypraeoidea, the cowries and cowry allies, is a Taxonomic rank, superfamily of sea snails, marine (ocean), marine gastropods included in the clade Littorinimorpha. This superfamily had been called Cypraeacea and was named by Rafinesque in 1815.MolluscaBase (2018). Cypraeoidea Rafinesque, 1815.

Cowry
Cowrie or cowry () is the common name for a group of small to large sea snails in the family Cypraeidae. Cowrie shells have held cultural, economic, and ornamental significance in various cultures. 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, in Somalia, 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 waters off Central California to Baja California (the chestnut cowrie is the only cowrie species native to the eastern Pacific Ocean off the coast of the United States; further south, off the coast of Mexico, Central America and Peru, Little Deer Cowrie habitat can be found; and ...

Cypraea Tigris
''Cypraea tigris'', commonly known as the tiger cowrie, is a species of cowry, a large sea snail, a marine gastropod mollusk in the family Cypraeidae, the cowries. Taxonomy The tiger cowry was one of the many species originally described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae'', and the species still bears its original name of ''Cypraea tigris''. Its specific epithet ''tigris'' relates to its common name "tiger" (the shell however is spotted, not striped). This species is the type species of the genus '' Cypraea''. Subspecies and forms * ''Cypraea tigris'' form ''incana'' Sulliotti, G.R., 1924 * ''Cypraea tigris'' form ''lyncicrosa'' Steadman, W.R. & B.C. Cotton, 1943 * ''Cypraea tigris'' var. ''schilderiana '' Cate, C.N., 1961 The variety ''Cypraea tigris'' var. ''schilderiana'' was recognized by Cate in 1961. It differs from ''Cypraea tigris'' in its large size (10–13 cm) and the lack of a thick marginal callus. This variety is found in t ...

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-Sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsum (anatomy)
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Termi ...

Operculum (gastropod)
An operculum (; ) is a corneous or calcareous anatomical structure like a trapdoor that exists in many (but not all) groups of sea snails and freshwater snails, and also in a few groups of land snails, including the Helicinidae, Cyclophoridae, Aciculidae, Maizaniidae, Pomatiidae, etc. The operculum is attached to the upper surface of the foot and in its most complete state, it serves as a sort of "trapdoor" to close the aperture (mollusc), aperture of the shell when the soft parts of the animal are retracted. The shape of the operculum varies greatly from one family of gastropods to another. It is fairly often circular, or more or less oval in shape. In species where the operculum fits snugly, its outline corresponds exactly to the shape of the aperture (mollusc), aperture of the shell and it serves to seal the entrance of the shell. Many families have opercula that are reduced in size, and which are not capable of closing the shell aperture. Opercula have sometimes been modifie ...

Crabs
Crabs are decapod crustaceans of the infraorder Brachyura (meaning "short tailed" in Greek), which typically have a very short projecting tail-like abdomen, usually hidden entirely under the thorax. Their exoskeleton is often thickened and hard. They generally have five pairs of legs, and they have "pincers" or "claws" on the ends of the frontmost pair, scientifically termed the '' chelae''. They are present in all the world's oceans, in freshwater, and on land, often hiding themselves in small crevices or burrowing into sediment. Crabs are omnivores, feeding on a variety of food, including a significant proportion of algae, as well as detritus and other invertebrates. Crabs are widely consumed by humans as food, with over 1.5 million tonnes caught annually. True crabs first appeared in the fossil record during the Jurassic period, around 200 million years ago, achieving great diversity by the Cretaceous period; around 7,000 extant species in 96 families are known.

Venom
Venom or zootoxin is a type of toxin produced by an animal that is actively delivered through a wound by means of a bite, sting, or similar action. The toxin is delivered through a specially evolved ''venom apparatus'', such as fangs or a stinger, in a process called ''envenomation''. Venom is often distinguished from ''poison'', which is a toxin that is passively delivered by being ingested, inhaled, or absorbed through the skin, and ''toxungen'', which is actively transferred to the external surface of another animal via a physical delivery mechanism. Venom has evolved in terrestrial and marine environments and in a wide variety of animals: both predators and prey, and both vertebrates and invertebrates. Venoms kill through the action of at least four major classes of toxin, namely necrosis, necrotoxins and cytotoxins, which kill cells; neurotoxins, which affect nervous systems; myotoxins, which damage muscles; and Hemotoxin, haemotoxins, which disrupt Thrombus, blood clotti ...

Conus Textile
''Conus textile'', the textile cone or the cloth of gold cone is a venomous species of sea snail, a marine gastropod mollusk in the family Conidae, the cone snails, cone shells or cones. Textile cone snails live mostly in the Indian Ocean, along the eastern coast of Africa and around Australia. Like all species within the genus ''Conus'', these snails are predatory and venomous. They are capable of stinging humans, therefore live ones should be handled carefully or not at all. Based on a report in 2004, about 30 human deaths have been attributed to cone snails.

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 (bivalve), 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 (mollusc), apex of the shell is called an orifice, and in the Haliotidae (abalone) where the row of respiratory openings in the shell are also called orifices.
