Sutton, Surrey
Sutton is the principal town in the London Borough of Sutton in South London, England. It lies on the lower slopes of the North Downs, and is the administrative headquarters of the Outer London borough. It is south-south west of Charing Cross, and is one of the thirteen metropolitan centres in the London Plan. The population of the town was counted as 41,483 in the 2011 census, while the borough overall counted 204,525. An ancient parish originally in the county of Surrey, Sutton is recorded in the ''Domesday Book'' of 1086 as having two churches and about 30 houses. Its location on the London to Brighton turnpike from 1755 led to the opening of coaching inns, spurring its growth as a village. When it was connected to central London by rail in 1847, it began to grow into a town, and it expanded further in the 20th century. It became a Municipal Borough of Sutton and Cheam, municipal borough with Cheam in 1934, and became part of Greater London in 1965. Sutton has the largest ...

Helminthology
Helminthology is the study of parasitic worms (helminths). The field studies the taxonomy of helminths and their effects on their hosts. The origin of the first compound of the word is the Greek '' ἕλμινς'' - helmins, meaning "worm". In the 18th and early 19th century there was wave of publications on helminthology; this period has been described as the science's "Golden Era". During that period the authors Félix Dujardin, William Blaxland Benham, Peter Simon Pallas, Marcus Elieser Bloch, Otto Friedrich Müller, , Biodiversity Heritage Library Johann Goeze, Friedrich Zenker, Charles Wardell Stiles, Carl Asmund Rudolphi, Otto Friedrich Bernhard von Linstow and Johann Gottfried Bremser started systematic scientific studies of the subject. The Japanese parasitologist Satyu Yamaguti was one of the most active helminthologists of the 20th century; he wrote the six-volume ''Systema Helminthum''.Anonymous. 1983. Special edition: A list of papers by Dr. Satyu Yamaguti and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sequential Hermaphroditism
Sequential hermaphroditism (called dichogamy in botany) is a type of hermaphroditism that occurs in many fish, gastropods, and plants. Sequential hermaphroditism occurs when the individual changes its sex at some point in its life. In particular, a sequential hermaphrodite produces eggs (female gametes) and sperm (male gametes) at different stages in life. Species that can undergo these changes from one sex to another do so as a normal event within their reproductive cycle that is usually cued by either social structure or the achievement of a certain age or size. In animals, the different types of change are male to female (protandry or protandrous hermaphroditism), female to male (protogyny or protogynous hermaphroditism), bidirectional (serial or bidirectional hermaphroditism). Both protogynous and protandrous hermaphroditism allow the organism to switch between functional male and functional female. Bidirectional hermaphrodites have the capacity for sex change in either directi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lethrinidae
The Lethrinidae are a family of fishes in the order Perciformes commonly known as emperors, emperor breams, and pigface breams. These fish are found in tropical waters of the Pacific and Indian Oceans, and ''Lethrinus atlanticus'' is also found in the eastern Atlantic Ocean. They are benthic feeders, consuming invertebrates and small fishes. Some species have molariform teeth which they use to eat shelled invertebrates, such as mollusks and crabs.

Seagrass
Seagrasses are the only flowering plants which grow in marine environments. There are about 60 species of fully marine seagrasses which belong to four families (Posidoniaceae, Zosteraceae, Hydrocharitaceae and Cymodoceaceae), all in the order Alismatales (in the clade of monocotyledons). Seagrasses evolved from terrestrial plants which recolonised the ocean 70 to 100 million years ago. The name ''seagrass'' stems from the many species with long and narrow leaves, which grow by rhizome extension and often spread across large "meadows" resembling grassland; many species superficially resemble terrestrial grasses of the family Poaceae. Like all autotrophic plants, seagrasses photosynthesize, in the submerged photic zone, and most occur in shallow and sheltered coastal waters anchored in sand or mud bottoms. Most species undergo submarine pollination and complete their life cycle underwater. While it was previously believed this pollination was carried out without pollinators ...

Penaeidae
Penaeidae is a family of marine crustaceans in the suborder Dendrobranchiata, which are often referred to as penaeid shrimp or penaeid prawns. The Penaeidae contain many species of economic importance, such as the tiger prawn, whiteleg shrimp, Atlantic white shrimp, and Indian prawn. Many prawns are the subject of commercial fishery, and farming, both in marine settings, and in freshwater farms. Lateral line–like sense organs on the antennae have been reported in some species of Penaeidae. At , the myelinated giant interneurons of pelagic penaeid shrimp have the world record for impulse conduction speed in any animal. Genera Of the 48 recognised genera in the family Penaeidae, 23 are known only from the fossil record (marked †): * † '' Albertoppelia'' Schweigert & Garassino, 2004 * † ''Ambilobeia'' Garassino & Pasini, 2002 * † ''Antrimpos'' Münster, 1839 * '' Artemesia'' Bate, 1888 * '' Atypopenaeus'' Alcock, 1905 * † '' Bombur'' Münster, 1839 * † ''Bylgia'' ...

Deception Bay, Queensland
Deception Bay is a coastal suburb in the Moreton Bay Region, Queensland, Australia. In the , Deception Bay had a population of 19,850 people. Geography It is approximately north of Brisbane CBD in the south-eastern corner of the bay of the same name which separates the Redcliffe Peninsula and Bribie Island. The suburb of Deception Bay takes its name from a small bay in the west of Moreton Bay, south of Pumicestone Passage and north of the Redcliffe Peninsula. In the north of the bay at Beachmere is where the Caboolture River and Burpengary Creek meet the ocean. It was named in 1823 by Lieutenant John Oxley, who thought the bay was a river and because of his mistake and the shallowness, named it Pumice Stone River; he later changed the name to Deception Bay.

Commonwealth Scientific And Industrial Research Organisation
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is an Australian Government agency responsible for scientific research. CSIRO works with leading organisations around the world. From its headquarters in Canberra, CSIRO maintains more than 50 sites across Australia and in France, Chile and the United States, employing about 5,500 people. Federally funded scientific research began in Australia years ago. The Advisory Council of Science and Industry was established in 1916 but was hampered by insufficient available finance. In 1926 the research effort was reinvigorated by establishment of the Council for Scientific and Industrial Research (CSIR), which strengthened national science leadership and increased research funding. CSIR grew rapidly and achieved significant early successes. In 1949, further legislated changes included renaming the organisation as CSIRO. Notable developments by CSIRO have included the invention of atomic absorption spectroscopy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grey Seals
The grey seal (''Halichoerus grypus'') is found on both shores of the North Atlantic Ocean. In Latin Halichoerus grypus means "hook-nosed sea pig". It is a large seal of the family Phocidae, which are commonly referred to as "true seals" or "earless seals". It is the only species classified in the genus ''Halichoerus''. Its name is spelled gray seal in the US; it is also known as Atlantic seal and the horsehead seal. Taxonomy There are two recognized subspecies of this seal: The type specimen of ''H. g. grypus'' (Zoological Museum of Copenhagen specimen ZMUC M11-1525, caught off the island of Amager, Danish part of the Baltic Sea) was believed lost for many years but was rediscovered in 2016, and a DNA test showed it belonged to a Baltic Sea specimen rather than from Greenland, as had previously been assumed (because it was first described in Otto Fabricius' book on the animals in Greenland: ''Fauna Groenlandica''). The name ''H. g. grypus'' was therefore transferred to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terranova (roundworm)
''Terranova'' is a genus of parasitic nematodes. Species from this genus are known to parasitise sharks, rays, sawfishes, teleosts and crocodilians.Sprent, J.F.A.

Anisakis
''Anisakis'' (a·nuh·saa·keez) is a genus of parasitic nematodes that have life cycles involving fish and marine mammals. They are infective to humans and cause anisakiasis. People who produce immunoglobulin E in response to this parasite may subsequently have an allergic reaction, including anaphylaxis, after eating fish infected with ''Anisakis'' species. Etymology The genus ''Anisakis'' was defined in 1845 by Félix Dujardin as a subgenus of the genus ''Ascaris'' Linnaeus, 1758. Dujardin did not make explicit the etymology, but stated that the subgenus included the species in which the males have unequal spicules ("''mâles ayant des spicules inégaux''"); thus, the name ''Anisakis'' is based on ''anis-'' (Greek prefix for different) and ''akis'' (Greek for spine or spicule). Two species were included in the new subgenus, ''Ascaris'' (''Anisakis'') ''distans'' Rudolphi, 1809 and ''Ascaris'' (''Anisakis'') simplex Rudolphi, 1809. Life cycle ''Anisakis'' species have c ...

Contracaecum
''Contracaecum'' is genus of parasitic nematodes from the family Anisakidae. These nematodes are parasites of warm-blooded, fish eating animals, i.e. mammals and birds, as sexually mature adults. The eggs and the successive stages of their larvae use invertebrates and increasing size classes of fishes as intermediate hosts. It is the only genus in the family Anisakidae which can infect terrestrial, marine and freshwater animals. Life cycle The adults live as parasites in the stomachs of piscivorous birds and mammals. As third stage larvae they attach to the stomach of the species of fish which are preyed on by their definitive host. When the intermediate host fish is eaten and reached the warm stomach of its predator the larvae of ''Contracaecum'' moult twice into adult males and females, producing eggs which are expelled into water in the faeces of the host. Where the water is shallow the eggs or larvae descend to the sea bed. Here they may be consumed by invertebrates while thos ...
