Tuatua
''Paphies subtriangulata'' is a species of edible bivalve clam known as tuatua in the Māori language, a member of the family Mesodesmatidae and endemic to New Zealand. It is found on all three of the main New Zealand islands, buried in fine clean sand on ocean beaches. The large shell is asymmetrical, with the hinge at one side. Its closest relative, the pipi (''Paphies australis''), has a symmetrical shell. Due to their shell shape, and how they burrow underneath the sand, they can withstand the high-energy waves from the ocean. Using this knowledge, we can identify where they will adapt the most to, and this is the energetic oceanfront. The soft parts of the animal are an edible delicacy, made into fritters or boiled and served on the shell. Historically the species has been used as a food source by the Māori, and its shell is a common component of excavated Māori middens. The clam burrows beneath the sand, and does so very quickly, making it a challenge to dig for at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paphies Australis
''Paphies australis'' or pipi (from the Māori language) is a bivalve mollusc of the family (biology), family Mesodesmatidae, endemic to New Zealand.MolluscaBase eds. (2021). MolluscaBase. Paphies australis (Gmelin, 1791). Accessed through: World Register of Marine Species at: http://marinespecies.org/aphia.php?p=taxdetails&id=505806 on 2021-06-03 The pipi is a shellfish with a solid white, elongated symmetrical shell with the apex at the middle. It is covered by a thin yellow periostracum. Its closest relative, the tuatua (''Paphies subtriangulata''), has an asymmetrical shell, with an off-centre hinge. The pipi is abundant on flat sandy beaches, in sandy and silty mud in estuaries, and harbours where there is considerable water flow. By releasing a thread of mucus, which makes them more buoyant, they are able to float in the water column and move to new locations. Where they find good living conditions, their numbers can exceed more than 1000 individuals per square metre. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Wood (zoologist)
William Wood FRS FLS (1774–1857), was an English surgeon, zoologist and entomologist. He was born in Kendal, Westmorland and trained in surgery at St Bartholomew's Hospital. He practised for several years as a surgeon at Wingham, near Canterbury and in London, but left the medical profession to become a natural history bookseller, publisher and naturalist. He was the author of several natural history books, especially on the Mollusca.

John Marwick
John Marwick (3 February 1891 – 17 August 1978) was a New Zealand palaeontologist and geologist. Early life and family Marwick was born near Oamaru, New Zealand, on 3 February 1891, the son of Hugh Marwick, and his wife, Jane née Cuthbert. While at Waitaki Boys' High School he helped to collect fossil shells and learned the beginnings of how to classify molluscs. He studied and taught at the University of Otago, and in 1912 gained an MA with first-class honours in with a thesis on geology. In 1915, he married Marion Ivy Mary Keys at Mosgiel. They had two sons and two daughters, all becoming science graduates. Career With the coming of the First World War Marwick joined the New Zealand Medical Corps in 1916, and was posted to Egypt. He served there as a medical orderly in the New Zealand Division, and also in Palestine, Sinai and Jordan. He won the Military Medal, and returned to Egypt, where he remained until 1919. In 1920 he became an assistant geologist in the New Zeal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By William Wood (zoologist)
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bivalves Described In 1828
Bivalvia () or bivalves, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of aquatic molluscs (marine and freshwater) that have laterally compressed soft bodies enclosed by a calcified exoskeleton consisting of a hinged pair of half-shells known as valves. As a group, bivalves have no head and lack some typical molluscan organs such as the radula and the odontophore. Their gills have evolved into ctenidia, specialised organs for feeding and breathing. Common bivalves include clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. Majority of the class are benthic filter feeders that bury themselves in sediment, where they are relatively safe from predation. Others lie on the sea floor or attach themselves to rocks or other hard surfaces. Some bivalves, such as scallops and file shells, can swim. Shipworms bore into wood, clay, or stone and ...

Endemic Fauna Of New Zealand
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Arthur William Baden Powell
Arthur William Baden Powell (4 April 1901 – 1 July 1987) was a New Zealand malacologist, naturalist and palaeontologist, a major influence in the study and classification of New Zealand molluscs through much of the 20th century. He was known to his friends and family by his third name, "Baden". Biography Early life The name Baden had been a given name in a Powell family since 1731, when Susannah Powell née Thistlethwayte (1696–1762) gave to her child (1731–1792) the maiden name of her mother, Susannah Baden (1663–1692). The name Baden, particularly when associated with the surname Powell, became famous in 1900–1901, the year Arthur William Baden Powell was born, because of the siege of Mafeking, the most famous British action in the Second Boer War, which turned the British commander of the besieged, Robert Baden-Powell, into a national hero. Throughout the British Empire, babies were named after him. No family connection has yet been established between Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gérard Paul Deshayes
Gérard Paul Deshayes (; 13 May 1795 – 9 June 1875) was a French geologist and conchologist. Career He was born in Nancy, his father at that time being professor of experimental physics in the École Centrale of the département Meurthe He studied medicine in Strasbourg, and afterwards took the degree of ''bachelier ès lettres'' in Paris in 1821; but he abandoned the medical profession in order to devote himself to natural history. For some time he gave private lessons on geology, and subsequently became professor of natural history in the Muséum National d'Histoire Naturelle. He was distinguished for his researches on the fossil mollusca of the Paris Basin and of other areas Cenozoic cover. His studies on the relations of the fossil to the recent species led him as early as 1829 to conclusions somewhat similar to those arrived at by Lyell, to whom Deshayes rendered much assistance in connection with the classification of the, then, Tertiary system into Eocene, Miocene a ...

Chatham Islands
The Chatham Islands ( ; Moriori language, Moriori: , 'Misty Sun'; ) are an archipelago in the Pacific Ocean about east of New Zealand's South Island, administered as part of New Zealand, and consisting of about 10 islands within an approximate radius, the largest of which are Chatham Island and Pitt Island, 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 Protected areas of New Zealand, nature reserves to conservation in New Zealand, conserve some of the unique flora and fauna. The islands were uninhabited when the Moriori people arrived around 1500 CE and developed Nunuku-whenua, 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 Moriori genocide, nearly exterminated the Moriori, slavery, enslaving the survivors. In the period of European colonisation, the New ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Midden
A midden is an old dump for domestic waste. It may consist of animal bones, human excrement, botanical material, mollusc shells, potsherds, lithics (especially debitage), and other artifacts and ecofacts associated with past human occupation. These features provide a useful resource for archaeologists who wish to study the diets and habits of past societies. Middens with damp, anaerobic conditions can even preserve organic remains in deposits as the debris of daily life are tossed on the pile. Each individual toss will contribute a different mix of materials depending upon the activity associated with that particular toss. During the course of deposition sedimentary material is deposited as well. Different mechanisms, from wind and water to animal digs, create a matrix which can also be analysed to provide seasonal and climatic information. In some middens individual dumps of material can be discerned and analysed. Shells A shell midden or shell mound is an arc ...
