Anarithma Maesi
''Anarithma maesi'' is a species of sea snail, a marine gastropod mollusk in the family Mitromorphidae.Rosenberg, G. (2012). Anarithma maesi Drivas & Jay, 1986. In: MolluscaBase (2017). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=594420 on 2018-02-05 Description Original description: "Globose, wide, biconical. The length of the narrow aperture is the same as the height of the spire. The sculpture consists of 15 axial plicae per whorl, overcrossed by spiral cords, 11 on the body whorl, followed by 11 more, slightly stronger and more widely spaced on the base. There are 4 riblets on the penultimate whorl, 2 on the preceding whorl, while the earlier whorls have only the two strongest cords. The protoconch is conical, smooth and brown and is made up of three and a half to four whorls. The shell is entirely pale brown, with a whitish spiral band on the upper part of the body whorl. The holotype is 4 mm in height and 2.1 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Brinsley Hinds
Richard Brinsley Hinds FRCS (11 October 1811, Aldermaston, England25 May 1846, Swan River, Western Australia) was a British naval surgeon, botanist and malacologist. He sailed on the 1835–42 voyage by HMS ''Sulphur'' to explore the Pacific Ocean, and edited the natural history reports of that expedition. Biography Hinds was born at Aldermaston on 11 October 1811, the eldest child of Richard Hinds, a surgeon in the Royal Navy, and his wife, Susannah (née Ridley). In 1829, he began studying at St Bartholomew's Hospital. In 1830, he matriculated at London University, where he gained an honours degree. He is reported to have been awarded the Gold Medal of the Worshipful Society of Apothecaries for botany, but no record of that seems to have survived. In 1833, he was accepted as a Member of the Royal College of Surgeons. On 28 February 1835, he joined the Royal Navy with the rank of Assistant Surgeon, and was appointed to the Royal Naval Hospital, Haslar. On 26 September 183 ...

Sea Snail
Sea snail is a common name for slow-moving marine gastropod molluscs, usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell. Definition Determining whether some gastropods should be called sea snails is not always easy. Some species that live in brackish water (such as certain neritids) can be listed as either freshwater snails or marine snails, and some species that live at or just above the high tide level (for example species in the genus '' Truncatella'') are sometimes considered to be sea snails and sometimes listed as land snails. Anatomy Sea snails are a very large group of animals and a very diverse one. Most snails that live in salt water respire using a gill or gills; a few species, though, have a lung, are intertidal, and are active only at low tide when they can move around in the air. These air-breathing species includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Mollusk
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 ...

Mitromorphidae
Mitromorphidae is a monophyletic family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.Bouchet, P. (2011). Mitromorphidae Casey, 1904. In: MolluscaBase (2018). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=153871 on 2018-02-05Bouchet P. & Rocroi J. P. (Ed.) (2005). "Classification and nomenclator of gastropod families". '' Malacologia'' 47(1–2). . 397 pp. Bouchet, Kantor ''et al''. elevated in 2011 the subfamily Mitromorphinae (which at that point had been placed in the family Conidae) to the rank of family. This was based on a cladistical analysis of shell morphology, radular characteristics, anatomical characters, and a dataset of molecular sequences of three gene fragments. Description The Mitromorphidae have small to medium-sized shells with a high biconic mitriform shape, a paucispiral or multispiral protoconch up to 4.5 whorls, a short or indistinct siphonal cana ...

Réunion
Réunion (; french: La Réunion, ; previously ''Île Bourbon''; rcf, label= Reunionese Creole, La Rényon) is an island in the Indian Ocean that is an overseas department and region of France. It is located approximately east of the island of Madagascar and southwest of the island of Mauritius. , it had a population of 868,846. Like the other four overseas departments, Réunion also holds the status of a region of France, and is an integral part of the French Republic. Réunion is an outermost region of the European Union and is part of the eurozone. Réunion and the fellow French overseas department of Mayotte are the only eurozone regions located in the Southern Hemisphere. As in the rest of France, the official language of Réunion is French. In addition, a majority of the region's population speaks Réunion Creole. Toponymy When France took possession of the island in the seventeenth century, it was named Bourbon, after the dynasty that then ruled France. To break ...
