Conchoderma Virgatum
''Conchoderma virgatum'' is a species of goose barnacle in the family Lepadidae. It is a pelagic species found in open water in most of the world's oceans attached to drifting objects or marine organisms. Description ''Conchoderma virgatum'' has a flexible, flattened, scale-less peduncle (stalk) which is attached to a solid surface, and a capitulum (body) with five smooth, four-sided plates, widely separated from each other and not clearly demarcated from the peduncle. The total length of this goose barnacle is about , half of which is the peduncle. Overall, the colour is grey, but there are some dark purplish-brown longitudinal streaks. Distribution ''Conchoderma virgatum'' has a cosmopolitan distribution, being found in all the world's oceans attached to a wide range of drifting and swimming objects, as well as benthic habitats. Ecology ''Conchoderma virgatum'' is found attached to a wider range of floating objects and nekton than goose barnacles in the genus ''Lepas''. This ...

Barnacles
A barnacle is a type of arthropod constituting the subclass Cirripedia in the subphylum Crustacea, and is hence related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings. They are sessile (nonmobile) and most are suspension feeders, but those in infraclass Rhizocephala are highly specialized parasites on crustaceans. They have four nektonic (active swimming) larval stages. Around 1,000 barnacle species are currently known. The name is Latin, meaning "curl-footed". The study of barnacles is called cirripedology. Description Barnacles are encrusters, attaching themselves temporarily to a hard substrate or a symbiont such as a whale ( whale barnacles), a sea snake ('' Platylepas ophiophila''), or another crustacean, like a crab or a lobster ( Rhizocephala). The most common among them, "acorn barnacles" ( Sessilia), are sessile where they grow their shells directly onto the substrate. Pedu ...

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 ...

Goose Barnacle
Goose barnacles, also called stalked barnacles or gooseneck barnacles, are filter-feeding crustaceans that live attached to hard surfaces of rocks and flotsam in the ocean intertidal zone. Goose barnacles formerly made up the taxonomic order Pedunculata, but research has resulted in the classification of stalked barnacles within multiple orders of the infraclass Thoracica. Biology Some species of goose barnacles such as '' Lepas anatifera'' are pelagic and are most frequently found on tidewrack on oceanic coasts. Unlike most other types of barnacles, intertidal goose barnacles (e.g. '' Pollicipes pollicipes'' and ''Pollicipes polymerus'') depend on water motion rather than the movement of their cirri for feeding, and are therefore found only on exposed or moderately exposed coasts. Spontaneous generation In the days before it was realised that birds migrate, it was thought that barnacle geese, ''Branta leucopsis'', developed from this crustacean through spontaneous ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Lorenz Spengler
Lorenz Spengler (22 September 1720 – 20 December 1807) was a Danish turner and naturalist. Born in Schaffhausen, Switzerland he arrived at Copenhagen in 1743 and became a tutor to Christian VI of Denmark and later Frederick V of Denmark in the art of turning. From 1771 he was head of the Royal Art Chamber (Det Kongelige Kunstkammer), a position he held until his death in 1807. Among his works is "''Beskrivelse og Oplysning over den hindindtil lidet udarbeidede Sloegt af mangeskallede Konchylier som Linnaeus har kaldet ''Lepas'' med tilfoiede nye og ubeskrevne Arter'' ", a treatise on shelled molluscs including many new species descriptions, of which six taxa are still valid. Spengler maintained a personal natural history collection, the ''Museo Spengleriano''. Spengler is commemorated in the scientific name of a species of Southeast Asian turtle, ''Geoemyda spengleri The black-breasted leaf turtle (''Geoemyda spengleri''), also commonly called the Vietnamese leaf turtl ...

Ignaz Von Olfers
Ignaz Franz Werner Maria von Olfers (30 August 1793 – 23 April 1871) was a German naturalist, historian and diplomat. Olfers was born in Münster. In 1816 he travelled to Brazil as a diplomat. In 1839 he was made director of the royal art collections and had significant influence on Frederick William IV of Prussia for a re-development of the Museumsinsel, Berlin. Together with architect Friedrich August Stueler, he developed the concept of the Neues Museum, Berlin and had great influence on organisation and presentation of exhibits and interior. His daughter was the writer and illustrator Marie von Olfers. Olfers described a number of new mammal species in Wilhelm Ludwig von Eschwege's ''Journal von Brasilien'' (1818). In 1819, '' Olfersia'' which is a genus of ferns (in the family Dryopteridaceae) from South America, was published, then a species of South American snake, ''Philodryas olfersii'' (in 1823),Beolens B, Watkins M, Grayson M (2011).

William Elford Leach
William Elford Leach FRS (2 February 1791 – 25 August 1836) was an English zoologist and marine biologist. Life and work Elford Leach was born at Hoe Gate, Plymouth, the son of an attorney. At the age of twelve he began a medical apprenticeship at the Devonshire and Exeter Hospital, studying anatomy and chemistry. By this time he was already collecting marine animals from Plymouth Sound and along the Devon coast. At seventeen he began studying medicine at St Bartholomew's Hospital in London, finishing his training at the University of Edinburgh before graduating MD from the University of St Andrews (where he had never studied). From 1813 Leach concentrated on his zoological interests and was employed as an 'Assistant Librarian' (what would later be called Assistant Keeper) in the Natural History Department of the British Museum, where he had responsibility for the zoological collections. Here he threw himself into the task of reorganising and modernising these coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
