Neoguraleus Sinclairi
''Neoguraleus sinclairi'' is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.Marshall, B.; Bouchet, P. (2015). Neoguraleus sinclairi (Gillies, 1882). In: MolluscaBase (2017). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=434474 on 2017-10-19 Not to be confused with ''Neoguraleus sinclairi'' (E.A.Smith, 1884) (synonym of '' Neoguraleus finlayi'' Powell, 1942). Authority Tucker (2004) states that ''Drillia sinclairi'' Gillies, 1882is a nude name, but it is not; Gillies (1882) renamed a misidentification by Hutton (1880), referring to p. 45 where Hutton gave a description of "Defranchia luteo-fasciata". This description is not copied from Reeve's description of "Pleurotoma luteo-fasciata". Description The length of the shell attains 11 mm, its diameter 4.5 mm.

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 A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial gastropod mollusks that have shells (those without shells are known .... Anatomy Sea snails are a very large group o ...

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 opi ...

Mangeliidae
Mangeliidae is a monophyletic family of small to medium-sized, predatory sea snails, marine gastropod mollusks in the superfamily Conoidea. Bouchet, P. (2011). Mangeliidae P. Fischer, 1883. In: MolluscaBase (2016). Accessed through: World Register of Marine Species at http://marinespecies.org/aphia.php?p=taxdetails&id=153853 on 2017-02-23Bouchet P. & Rocroi J.-P. (Ed.) (2005). "Classification and nomenclator of gastropod families". '' Malacologia'' 47(1-2). . 397 pp. Prior to 2011, both the subfamilies Mangeliinae and Oenopotinae had been placed in the family Conidae. In 2011, Bouchet, Kantor ''et al'' merged the two subfamilies into one taxon, which they elevated to the rank of family. This was based on anatomical characters and a dataset of molecular sequences of three gene fragments. Mangeliidae is a sister-clade to the family Raphitomidae As with their relatives in the family Conidae, species in the family Mangelidae use potent venoms to catch their prey. Through th ...

Neoguraleus Finlayi
''Neoguraleus finlayi'' is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.Marshall, B. (2015). Neoguraleus finlayi Powell, 1942. In: MolluscaBase (2017). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=434467 on 2017-10-17 Description The length of the shell attains 10 mm, its diameter 4 mm. The small, solid shell is ovate and subturriculated. It is axially costate and spirally lirate, usually with 2 brown spiral bands. The sculpture consistis of rounded and rather low axial ribs, 10 to 16 on the body whorl. The interstices are of about the same width as the ribs, which are mostly obsolete on the very narrow shoulder or depression of the lower whorls, continued nearly to the base. They are crossed by more or less distinct spiral lirae, continuous between and across the ribs, stouter upon the neck of the siphonal canal. The colour of the shell is light flavescent, with 2 redd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steward Island
Steward Island ( da, Steward Ø; also ''Stewart Ø'' in some sources)''Prostar Sailing Directions 2005 Greenland and Iceland Enroute'', p. 111 is an uninhabited island in King Christian IX Land, at the eastern end of Greenland. Administratively it is part of the Sermersooq municipality. The island is mountainous and clearly visible from a distance. According to mariners' reports the island is a good landmark for vessels approaching Greenland from the east. Geography Steward is a coastal island of the Blosseville Coast located in a bay off the Savoia Peninsula. It lies 39 km to the SW of Cape Brewster and 7.5 km to the northeast of the small Manby Peninsula. To the west there is a wide glacier discharging in the bay and the island's western end is attached to the terminus of the glacier, so that it almost forms a peninsula with the mainland. The island is long with a maximum width of . The small Dunholm islets ''(Dunholm Øer)'' lie 4 km to the east and the high Pyramiden, ...

Chatham Islands
The Chatham Islands ( ) ( Moriori: ''Rēkohu'', 'Misty Sun'; mi, Wharekauri) are an archipelago in the Pacific Ocean about east of New Zealand's South Island. They are administered as part of New Zealand. The archipelago consists of about ten islands within an approximate radius, the largest of which are Chatham Island and Pitt Island (Rangiauria). They include New Zealand's easternmost point, the Forty-Fours. Some of the islands, formerly cleared for farming, are now preserved as nature reserves to conserve some of the unique flora and fauna. The islands were uninhabited when the Moriori people arrived around 1500 CE and developed a peaceful way of life. In 1835 members of the Ngāti Mutunga and Ngāti Tama Māori iwi from the North Island of New Zealand invaded the islands and nearly exterminated the Moriori, enslaving the survivors. Later during the period of European colonisation of New Zealand, the New Zealand Company claimed that the British Crown had never ...
