Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Livonia Mervcooperi
Livonia ( liv, Līvõmō, et, Liivimaa, fi, Liivinmaa, German and Scandinavian languages: ', archaic German: ''Liefland'', nl, Lijfland, Latvian and lt, Livonija, pl, Inflanty, archaic English: ''Livland'', ''Liwlandia''; russian: Лифляндия, Liflyandiya) is a historical region on the eastern shores of the Baltic Sea. It is named after the Livonians, who lived on the shores of present-day Latvia. By the end of the 13th century, the name was extended to most of present-day Estonia and Latvia, which had been conquered during the Livonian Crusade (1193–1290) by the Livonian Brothers of the Sword. Medieval Livonia, or Terra Mariana, reached its greatest extent after Saint George's Night Uprising that in 1346 forced Denmark to sell the Duchy of Estonia (northern Estonia conquered by Denmark in the 13th century) to the State of the Teutonic Order. Livonia, as understood after the retreat of Denmark in 1346, bordered on the Gulf of Finland in the north, Lake Pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fulgorariinae
The subfamily Fulgorariinae contains sea snails, marine gastropod mollusks in the family Volutidae.MolluscaBase eds. (2020). MolluscaBase. Fulgorariinae Pilsbry & Olsson, 1954. Accessed through: World Register of Marine Species at: https://www.marinespecies.org/aphia.php?p=taxdetails&id=394992 on 2020-11-26 Description They are characterized by a uniserial radula with tricuspid teeth. Lateral cusps are thickest along the lateral edge, broader and generally longer than the central cusps. The protoconch is large or small, papilliform and often tilted on its vertical axis. Shells are fusiform and show numerous irregular columellar plaits. Distribution Most of the species thrive in the benthic zone between 100 and 300 m on mud and shell grit substrate. Rare bathyal species are brought up from 800 to 1000 m. The distribution of the Fulgorariinae extends along the East coast of Asia, from throughout Japan except the Okhotsk Sea, the Pacific coast, the Japan Sea, the East China Sea and ...

Cymbiinae
''Volutidae'', common name volutes, are a taxonomic family of predatory sea snails that range in size from 9 mm to over 500 mm. They are marine gastropod mollusks. Most of the species have no operculum. Distribution This family of sea snails are found mainly in tropical seas, though some species also inhabit the waters of the polar circles. Shell description The shell of species such as ''Melo amphora'' can grow as large as 50 cm (19.7 inches) in length.Poutiers, J. M. (1998). Gastropods in: FAO Species Identification Guide for Fishery Purposes: The living marine resources of the Western Central Pacific Volume 1. Seaweeds, corals, bivalves and gastropods. Rome, FAO, 1998. page 597. Volutes are distinguished by their distinctively marked spiral shells (to which the family name refers, ''voluta'' meaning "scroll" in Latin).

John Edward Gray
John Edward Gray, FRS (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.
