Giuseppe Saverio Poli
Giuseppe Saverio Poli (26 October 17467 April 1825) was an Italian physicist, biologist and natural historian. His collections, together with those stored in the Royal Bourbon Museum, were the foundation of the Zoological Museum of Naples. The specimens were from locations all over the world, and included especially, Lepidoptera, Cnidaria and Mollusca. Biography Giuseppe Saverio Poli was born in 1746 and was the son of Vito Angelo di Giuseppe and Eleonora Corlè. In 1766 he enrolled at the University of Padua, where he graduated in medicine. He briefly worked as a doctor in Molfetta, but in 1790 he moved to Naples to teach history and geography at the Nunziatella Military School, for which, once he became commander, with the rank of lieutenant colonel, he took care of the department of physics. In 1775 he toured Europe on behalf of the academy, visiting many seats of learning in Germany, France, England and the Netherlands and meeting naturalists and scientists. This enabled ...

Marine (ocean)
The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the world ocean is conventionally divided."Ocean." ''Merriam-Webster.com Dictionary'', Merriam-Webster, |
Bivalve
Bivalvia (), in previous centuries referred to as the Lamellibranchiata and Pelecypoda, is a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. As a group, bivalves have no head and they lack some usual molluscan organs, like the radula and the odontophore. They include the clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders. The gills have evolved into ctenidia, specialised organs for feeding and breathing. Most bivalves 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 the scallops and file shells, can swim. The shipworms bore into wood, clay, or stone and live inside these substances. The shell of a bivalve is composed of calc ...

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species. The gastropods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Glycymerididae
Glycymerididae, often misspelled as Glycymeridae, common names dog cockles or bittersweets, is a worldwide family of salt water clams, marine bivalve mollusks in the order Arcida. They are related to the ark clams. This family contains 45 extant species in four genera. Description In this family the shell is generally round in outline and is slightly longer than it is wide. The external ligament lacks transverse striations. The shell in some genera is smooth and in others it is ribbed. History of the name Authority of Glycymerididae has been incorrectly attributed to Newton (1916 or 1922) by a great number of authors. While Newton was the first to publish this name, Dall (1908) had previously established the subfamily Glycymerinae , which gives him priority for the family name under Article 36 of ICZN. The name comes from the Ancient Greek word ''glykymaris'' (perhaps from ''glykýs'' "sweet" and ''méros'' "part"), a word which is only recorded once in Greek literature. T ...

Glycymeris
''Glycymeris'', common name the bittersweet clams, is a genus of saltwater clams, marine bivalve molluscs in the family Glycymerididae.MolluscaBase eds. (2022). MolluscaBase. Glycymeris da Costa, 1778. Accessed through: World Register of Marine Species at: https://www.marinespecies.org/aphia.php?p=taxdetails&id=138035 on 2022-04-19 Etymology The genus name comes from the Ancient Greek word ''glykymaris'' (perhaps from ''Glykys'' (sweet) and ''Meris'' (part)), a word which is only recorded once in Greek literature. Fossil records These clams are very common as fossils, from the Cretaceous period in the Valanginian age (between 140.2 ± 3.0 mya and 136.4 ± 2.0 mya). Fossil shells of these molluscs can be found all over the world. Genus ''Glycymeris'' includes about 100 extinct species. Description The shells are generally biconvex, with equal valves round in outline, and slightly longer than wide. Their size varies from medium to large. The external ligament lacks transv ...
