''Nassarius granifer'', common name the granulated dog whelk or granulated nassa, is a species of sea snail with an operculum, a marine gastropod mollusc in the family Nassariidae, the mud snails or dog whelks.MolluscaBase eds. (2021). MolluscaBase. Nassarius granifer (Kiener, 1834). Accessed through: World Register of Marine Species at: http://marinespecies.org/aphia.php?p=taxdetails&id=560218 on 2021-09-06 Description The length of the shell of this species varies between 10 mm and 18 mm. The shell is rather small, ovate, thick and globular. Its color is of an ash-white. The spire is conical and, pointed, composed of six whorls, the lowest much larger than all the other. This body whorl presents on its surface conical, distant tubercles, disposed in four series. A few transverse striae ornament the base. The upper whorls have only a single row of tubercles. The ovate aperture is narrow, emarginated at the upper part, at its union with the outer lip, which is thick, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis Charles Kiener
Louis Charles Kiener (31 July 1799 – 24 July 1881) was a French malacologist born in Paris. He was the author of the 12-volume ''Spécies général et iconographie des coquilles vivantes comprenant la collection du Muséum d'histoire naturelle de Paris, la collection Lamarck, celle du prince Masséna (appartenant maintenant a M.B. Delessert) et les découvertes récentes des voyageurs'', translated into English as "General species and iconography of recent shells : comprising the Massena Museum, the collection of Lamarck, the collection of the Muséum national d'histoire naturelle, Museum of Natural History, and the recent discoveries of travellers.

Lip (gastropod)
In the shell of gastropod mollusks (a snail shell), the lip is the free margin of the peristome (synonym: peritreme) or aperture (mollusc), aperture (the opening) of the gastropod shell. In dextral (right-handed) shells (most snail shells are right-handed), the right side or outer side of the aperture is known as the outer lip (''labrum''). The left side of the aperture is known as the inner lip or columellar lip (''labium'') if there is a pronounced lip there. In those species where there is no pronounced lip, the part of the body whorl that adjoins the aperture is known as the parietal wall. The outer lip is usually thin and sharp in immature shells, and in some adults (e.g. the land snails ''Helicella'' and ''Bulimulus''). However, in some other land snails and in many marine species the outer lip is ''thickened'' (also called ''callused''), or ''reflected'' (turned outwards). In some other marine species it is curled inwards (''inflected''), as in the cowries such as ''Cypraea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mascarene
The Mascarene Islands (, ) or Mascarenes or Mascarenhas Archipelago is a group of islands in the Indian Ocean east of Madagascar consisting of islands belonging to the Republic of Mauritius as well as the French department of Réunion. Their name derives from the Portuguese navigator Pedro Mascarenhas, who first visited them in April 1512. The islands share a common geological origin beneath the Mascarene Plateau known as the Mauritia microcontinent which was a Precambrian microcontinent situated between India and Madagascar until their separation about 70 million years ago. They form a distinct ecoregion with unique biodiversity and endemism of flora and fauna. Geography The archipelago comprises three large islands, Mauritius, Réunion, and Rodrigues, plus a number of volcanic remnants in the tropics of the southwestern Indian Ocean, generally between 700 and 1,500 kilometres east of Madagascar. The terrain includes a variety of reefs, atolls, and small islands. They pres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chagos
The Chagos Archipelago (, ) or Chagos Islands (formerly , and later the Oil Islands) is a group of seven atolls comprising more than 60 islands in the Indian Ocean about south of the Maldives archipelago. This chain of islands is the southernmost archipelago of the Chagos–Laccadive Ridge, a long submarine mountain range in the Indian Ocean. In its north are the Salomon Islands, Nelsons Island and Peros Banhos; towards its south-west are the Three Brothers, Eagle Islands, Egmont Islands and Danger Island; southeast of these is Diego Garcia, by far the largest island. All are low-lying atolls, save for a few extremely small instances, set around lagoons. From 1715 to 1810, the Chagos Islands were part of France's Indian Ocean possessions, administered through Isle de Francewhich was a colony of France (later renamed as Mauritius).

Aldabra
Aldabra, the world's second-largest coral atoll (the largest is Kiritimati), is located east of the continent of Africa. It is part of the Aldabra Group of islands in the Indian Ocean that are part of the Outer Islands (Seychelles), Outer Islands of the Seychelles, with a distance of 1,120 km (700 mi) southwest of the capital, Victoria, Seychelles, Victoria on Mahé, Seychelles, Mahé Island. Initially named by Arab seafarers for its harsh environment, Aldabra became a French colonial empire, French colony dependency in the 18th century, leading to the exploitation of its natural resources, particularly giant tortoises. After passing through British hands, Aldabra faced potential military use in the 1960s, but international protests resulted in its protection. The atoll boasts unique geography, featuring the world's largest raised coral reef and a large shallow lagoon. Aldabra's history involves human impact, including failed agricultural ventures.

Today, the greatest proportion of the population is of mixed descent, while the predominant language is Réunion Creole, though French remains the sole official language.

Columella (genus)
''Columella'' is a genus of very small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Truncatellinidae, the whorl snails and allies. Taxonomy ''Columella'' is commonly classified within the Vertiginidae. However, as shown by Nekola & Coles (2016), the genus is not that closely related to the Vertiginidae, but may rather be affiliated with the Chondrinidae or form a pupilloid family of its own. A systematic revision is pending. Species Species within the genus ''Columella'' include: * '' Columella acicularis'' Almuhambetova, 1979 * ''Columella aspera'' Waldén, 1966 * '' Columella columella'' ( G. v.

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.
