Thomas Martyn (zoologist)
Thomas Martyn (probably 1760 – 1816) was an English zoologist, conchologist and entomologist. He should not be confused with the botanist of the same name. Life Little is known about Thomas Martyn's life and nothing about his parents, his wife and his children. It is believed that he was born in 1760 in Coventry. Later he lived at several addresses in London. At 10 Great Marlborough Street, Westminster he established an academy for the painting of Natural History. Besides English, Martyn spoke French and Latin. Works In 1784, Martyn started his major work, ''The Universal Conchologist'', which he completed and published in London in 1784, dedicating it to the King. His publications included: * ''Hints of important Uses to be derived from Aerostatic Globes. With a Print of an Aerostatic Globe … originally designed in 1783'', 1784. * ''The Universal Conchologist, exhibiting the figure of every known Shell'', with second title ''Figures of non-descript Shells collected in t ...

Henry Suter
Henry Suter (born Hans Heinrich Suter, 9 March 1841 – 31 July 1918) was a Swiss-born New Zealand zoologist, naturalist, palaeontologist, and malacologist. Biography Henry Suter was born on 9 March 1841 in Riesbach, Zurich, Switzerland, and was the son of a prosperous silk-manufacturer of Zurich. He was educated at the local school and university, being trained as an analytical chemist. Suter joined his father's business, and for some years he engaged in various commercial pursuits. From his boyhood, Henry Suter was deeply interested in natural history. He enjoyed the friendship and help of such men as Dr. Auguste Forel, Professor Paul Godet, the brothers de Saussure (linguist Ferdinand de Saussure, Sinolog and astronomer Léopold de Saussure and René de Saussure Esperantist and scientist), Escher von der Linth, and especially the well-known conchologist, Dr. Albert Mousson. Partly to improve his financial prospects and partly lured by the attraction of the fauna of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limpet
Limpets are a group of aquatic snails that exhibit a conical shell shape (patelliform) and a strong, muscular foot. Limpets are members of the class Gastropoda, but are polyphyletic, meaning the various groups called "limpets" descended independently from different ancestral gastropods. This general category of conical shell is known as "patelliform" (dish-shaped). All members of the large and ancient marine clade Patellogastropoda are limpets. Within that clade, the members of the Patellidae family in particular are often referred to as "true limpets". Other groups, not in the same family, are also called limpets of one type or another, due to the similarity of their shells' shape. Examples include the Fissurellidae ("keyhole limpet") family, which is part of the Vetigastropoda clade (many other members of the Vetigastropoda do not have the morphology of limpets) and the Siphonariidae ("false limpets"), which use a siphon to pump water over their gills.

Marine (ocean)
The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the world ocean is conventionally divided."Ocean." ''Merriam-Webster.com Dictionary'', Merriam-Webster, |
Gastropod
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.

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Nacellidae
Nacellidae is a taxonomic family of sea snails or true limpets, marine gastropod molluscs in the subclass Patellogastropoda. Taxonomy Nacellidae was the only family in the superfamily Nacelloidea as described by Bouchet & Rocroi (2005),. However a molecular phylogenetic study of Patellogastropoda by Nakano & Ozawa (2007) found that Nacellidae was recovered within Lottioidea, as shown in the following cladogram:Nakano T. & Ozawa T. (2007). "Worldwide phylogeography of limpets of the order Patellogastropoda: Molecular, morphological and palaeontological evidence". ''Journal of Molluscan Studies'' 73(1) 79-99. . As a result Nacellidae was moved to Lottioidea in the taxonomic revision of Bouchet et al (2017). More recently, a recent phylogenomic study found Nacellidae as a sister to Patellidae, which suggests that Nacellidae should be transferred to Patelloidea. Genera Genera within the family Nacellidae include: * ''Cellana'' H. Adams, 1869 * '' Naccula'' Iredale, 1924Ir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cellana Flava 001
''Cellana'' is a genus of sea snails or limpets, marine gastropod molluscs in the family Nacellidae, the true limpets.WoRMS (2010). Cellana H. Adams, 1869. In: Bouchet, P.; Gofas, S.; Rosenberg, G. (2010) World Marine Mollusca database. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=205749 on 2010-10-31 Distribution This genus occurs in the temperate and tropical Indo-Pacific oceans, Hawaii (where they are known as ''‘opihi'' and considered a delicacy) and around Australia and New Zealand. Species are also found around the coasts of Japan, the Red Sea, Mauritius, Madagascar, South Africa and the sub-Antartarctic Islands. One species, ''Cellana radiata'', is cosmopolitan. These sea snails feed by grazing on green macroalgae growing on rocky substrate in the intertidal zone. Some of these limpets can live up to 7 years, however most do not get older than 2–3 years. They reproduce by broadcasting their spawn in larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur William Baden Powell
Arthur William Baden Powell (4 April 1901 – 1 July 1987) was a New Zealand malacologist, naturalist and palaeontologist, a major influence in the study and classification of New Zealand molluscs through much of the 20th century. He was known to his friends and family by his third name, "Baden". Biography Early life The name Baden had been a given name in a Powell family since 1731, when Susannah Powell née Thistlethwayte (1696–1762) gave to her child (1731–1792) the maiden name of her mother, Susannah Baden (1663–1692). The name Baden, particularly when associated with the surname Powell, became famous in 1900–1901, the year Arthur William Baden Powell was born, because of the siege of Mafeking, the most famous British action in the Second Boer War, which turned the British commander of the besieged, Robert Baden-Powell, into a national hero. Throughout the British Empire, babies were named after him. No family connection has yet been established between Arthur W ...
