Hiatella Azaria
''Hiatella'' is a genus of small saltwater clams, marine bivalve molluscs in the family Hiatellidae. Ecology These bivalves are stationary suspension feeders. Some species bore into rock for shelter, others also live in rock but do not bore, instead they nestle in holes created by other organisms, or in other crevices. They may also live nestled within the holdfasts of kelps, within other organisms such as sponges, or partly buried in a sandy sediment. Species The number of species in the genus is unclear, and their unequivocal identification can be difficult. The following species are listed in MolluscaBase/WoRMS (2015): * ''Hiatella antarctica'' (Philippi, 1845) * ''Hiatella arctica'' ( Linnaeus, 1767) (= ''Hiatella striata'' (Fleuriau, 1802) = ''Hiatella pholadis'' ( Linnaeus, 1771)) * '' Hiatella arenacea'' (E.A. Smith, 1910) * '' Hiatella australis'' (Lamarck, 1818) * '' Hiatella azaria'' Dall, 1881 * ''Hiatella rugosa'' ( Linnaeus, 1767) (= ''Hiatella gallicana'' (Lamar ...

Valve (mollusc)
A valve is each articulating part of the shell of a mollusc or another multi-shelled animal such as brachiopods and some crustaceans. Each part is known as a valve or in the case of chitons, a "plate". Members of two classes of molluscs, the Bivalvia (clams) and the Polyplacophora (chitons), have valves. Species within one family of very unusual small sea snails, marine opisthobranch gastropods in the family Juliidae, also have two articulating shells or valves, which resemble those of a bivalve. This exceptional family is commonly known as the bivalved gastropods. Gastropods in general are sometimes called "univalves", because in those that have a shell, the shell is usually in one part. Chitons The valves of chitons are eight dorsal, articulated shell plates, which are frequently coloured and sculpted. After death the girdle that holds the plates together disintegrates and the plates separate. Thus individual plates can be found washed up in beach drift, as shown in the ...

Molecular Systematics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Natural History - Mollusca - Saxicava
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant " birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word '' physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-So ...
