Pollicipes Pollicipes
''Pollicipes pollicipes'', known as the goose neck barnacle, goose barnacle or leaf barnacle is a species of goose barnacle, also well known under the taxonomic synonym ''Pollicipes cornucopia''. It is closely related to '' Pollicipes polymerus'', a species with the same common names, but found on the Pacific coast of North America, and to '' Pollicipes elegans'' a species from the coast of Chile. It is found on rocky shores in the north-east Atlantic Ocean and is prized as a delicacy, especially in the Iberian Peninsula. Distribution ''Pollicipes pollicipes'' is chiefly distributed from 48°N to 28°N, along the coasts of France, Spain (including the Canary Islands), Portugal, Morocco, and south to Senegal. The periphery of the species' range also extends as far north as the British Isles, with outlying populations on the south coast of England and possibly in southwestern Ireland, although there are no recent records there. The species is present, but rare, in the Mediterrane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pollicipes Polymerus
''Pollicipes polymerus'', commonly known as the gooseneck barnacle or leaf barnacle, is a species of stalked barnacle. It is found, often in great numbers, on rocky shores on the Pacific coasts of North America. Classification Barnacles are classified with shrimps, crabs, isopods and amphipods in the subphylum Crustacea. They are included in the class Maxillopoda, though this class does not appear to be a monophyletic grouping. They are included in the infraclass Cirripedia, the barnacles, members of which are sessile suspension feeders with two active swimming larval stages, the nauplius and the cyprid. The order Pedunculata includes barnacles attached to the substrate by stalks, the goose barnacles. The attachment is made by the cementing of the antennules of the cyprid larvae to the substrate and the elongation of that region into a stalk. Pedunculata is not itself a single monophyletic group but forms a transitional series of lineages moving towards the sessile acorn barnac ...

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 gen ...

Pollicipes Caboverdensis
''Pollicipes caboverdensis'' is a species of goose barnacle in the family Pollicipedidae. It is found in rocky intertidal zones on the coasts of the islands Santiago Santiago (, ; ), also known as Santiago de Chile, is the capital and largest city of Chile as well as one of the largest cities in the Americas. It is the center of Chile's most densely populated region, the Santiago Metropolitan Region, whos ..., Sal and São Vicente, Cape Verde. The species was first described by Joana N. Fernandes, Teresa Cruz and Robert Van Syoc in 2010 after a 24.5 mm specimen collected from Ponta Preta, northwestern Santiago.

William Elford Leach
William Elford Leach Royal Society, 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 Royal Devon and Exeter Hospital, 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 Doctor of Medicine, 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 Museum, London, Natural History Department of the British Museum, where he had responsibility for the zoological ...

Genus (biology)
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 clearly demons ...

Marine Habitats
Marine habitats are habitats that support marine life. Marine life depends in some way on the saltwater that is in the sea (the term ''marine'' comes from the Latin ''mare'', meaning sea or ocean). A habitat is an ecological or environmental area inhabited by one or more living species.Abercrombie, M., Hickman, C.J. and Johnson, M.L. 1966.''A Dictionary of Biology.'' Penguin Reference Books, London The marine environment supports many kinds of these habitats. Marine habitats can be divided into coastal and open ocean habitats. Coastal habitats are found in the area that extends from as far as the tide comes in on the shoreline out to the edge of the continental shelf. Most marine life is found in coastal habitats, even though the shelf area occupies only seven percent of the total ocean area. Open ocean habitats are found in the deep ocean beyond the edge of the continental shelf. Alternatively, marine habitats can be divided into pelagic and demersal zones. Pelagic habitats a ...

Filter Feeder
Filter feeders are a sub-group of suspension feeding animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialized filtering structure. Some animals that use this method of feeding are clams, krill, sponges, baleen whales, and many fish (including some sharks). Some birds, such as flamingos and certain species of duck, are also filter feeders. Filter feeders can play an important role in clarifying water, and are therefore considered ecosystem engineers. They are also important in bioaccumulation and, as a result, as indicator organisms. Fish Most forage fish are filter feeders. For example, the Atlantic menhaden, a type of herring, lives on plankton caught in midwater. Adult menhaden can filter up to four gallons of water a minute and play an important role in clarifying ocean water. They are also a natural check to the deadly red tide.
