Pholadidea
''Pholadidea'' is a taxonomic genus of marine bivalve molluscs in the subfamily Martesiinae of the family Pholadidae (the piddocks). Most members of ''Pholididea'' bore into shale, soft rock and coral for shelter, with the exception of ''Pholididea (Hatasia) wiffenae'', which is a wood-borer. Appearance The ''Pholididea'' are distinguished from the other genera in Martesiinae by having only on umbonal-ventral sulcus, a longitudinally-divided mesoplax, and either no metaplax and hypoplax, or a single plate caused by deposition of calcite in the periostratum. Occurrence ''Pholididea'' is known from the Eocene to the Holocene, while the subgenus ''P. (Hatasia)'' is known only from the Holocene. Species have been reported from the Palaeocene and Late Cretaceous, but these likely belong in other genera. Taxonomy The following taxonomic classifications exist in ''Pholididea'': Subgenera * '' Pholadidea (Pholadidea)'' Turton, 1819 * '' Pholadidea (Hatasia)'' Gray, 1851 Spe ...

Pholadidae
Pholadidae, known as piddocks or angelwings, are a family of bivalve molluscs similar to a clam. Background Piddocks are unique in that each side of their shells is divided into 2 or 3 separate sections. Furthermore, one of the piddock's shells has a set of ridges or "teeth", which they use to grind away at clay or soft rock and create tubular burrows. The shape of these burrows are due to the rotating motion of the piddock as it grinds the rock to make its home. The piddock stays in the burrow it digs for the entirety of its eight-year lifespan, with only its siphon exposed to take in water that it filters for food. When the piddock dies and leaves an empty tubular burrow, other marine life such as sea anemone, crabs and other molluscs may use the burrow. Some species of Pholadidae may reach up to 18 cm (7″). Their coloration is typically white, though through consumption of red tide algae some may develop a pink coloration. * The angelwing species ''Cyrtopleura costata' ...

George Brettingham Sowerby I
George Brettingham Sowerby I (12 August 1788 – 26 July 1854) was a British naturalist, illustrator and conchologist. Life He was the second son of James Sowerby. George was educated at home under private tutors, and afterwards assisted his father in the production of illustrated works on natural history. On the latter's death in 1822, he and his brother James De Carle Sowerby continued their father's work on fossil shells, publishing the latter parts of the ''Mineral Conchology of Great Britain''. He published about 50 papers on molluscs and started several comprehensive, illustrated books on the subject, the most important the ''Thesaurus Conchyliorum'', a work that was continued by his son, George Brettingham Sowerby II and his grandson George Brettingham Sowerby III. One of his first works was the cataloguing of the collection of the Earl of Tankerville. He also dealt in shells and natural history objects, his place of business being first in King Street, Covent Garden, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
