Emanuel Mendes Da Costa
Emanuel Mendes da Costa (5 June 1717 – 31 May 1791) was an England, English Botany, botanist, natural history, naturalist, Philosophy, philosopher, and collector of valuable notes and of manuscripts, and of anecdotes of the literati. Da Costa became infamous for embezzling funds while working at the Royal Society in London and was imprisoned. Biography Da Costa came from a Sephardi family that had moved to England in the 1600s from Portugal. His parents were Abraham and Esther (with the Christian names of John and Joanna). Abraham is thought to have been in the diamond business. A brother became a wealthy businessman but Emanuel worked in the office of a notary and qualified from the Scriveners' Company in 1762 but had taken an interest in natural history from around 1736. He began to trade in shells, corals and fossils and corresponded with Carl Linnaeus, Sir Hans Sloane and other naturalists of the period. Da Costa was elected one of the first Jewish Fellows of the Royal Soci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volubilis
Volubilis (; ar, وليلي, walīlī; ber, ⵡⵍⵉⵍⵉ, wlili) is a partly excavated Berber-Roman city in Morocco situated near the city of Meknes, and may have been the capital of the kingdom of Mauretania, at least from the time of King Juba II. Before Volubilis, the capital of the Kingdom may have been at Gilda. Built in a fertile agricultural area, it developed from the 3rd century BC onward as a Berber, then proto-Carthaginian, settlement before being the capital of the kingdom of Mauretania. It grew rapidly under Roman rule from the 1st century AD onward and expanded to cover about with a circuit of walls. The city gained a number of major public buildings in the 2nd century, including a basilica, temple and triumphal arch. Its prosperity, which was derived principally from olive growing, prompted the construction of many fine town-houses with large mosaic floors. The city fell to local tribes around 285 and was never retaken by Rome because of its remoteness and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trematode
Trematoda is a class of flatworms known as flukes. They are obligate internal parasites with a complex life cycle requiring at least two hosts. The intermediate host, in which asexual reproduction occurs, is usually a snail. The definitive host, where the flukes sexually reproduce, is a vertebrate. Infection by trematodes can cause disease in all five traditional vertebrate classes: mammals, birds, amphibians, reptiles, and fish. Etymology Trematodes are commonly referred to as flukes. This term can be traced back to the Old English name for flounder, and refers to the flattened, rhomboidal shape of the organisms. Taxonomy There are 18,000 to 24,000 known species of trematodes, divided into two subclasses — the Aspidogastrea and the Digenea. Aspidogastrea is the smaller subclass, comprising 61 species. These flukes mainly infect bivalves and bony fishes.https://www.biotaxa.org/Zootaxa/article/view/zootaxa.3918.3.2 Digenea — which comprise the majority of trematodes — ...

Aestivate
Aestivation ( la, aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. It takes place during times of heat and dryness, the hot dry season, which are often the summer months. Invertebrate and vertebrate animals are known to enter this state to avoid damage from high temperatures and the risk of desiccation. Both terrestrial and aquatic animals undergo aestivation. Fossil records suggest that aestivation may have evolved several hundred million years ago. Physiology Organisms that aestivate appear to be in a fairly "light" state of dormancy, as their physiological state can be rapidly reversed, and the organism can quickly return to a normal state.

Umbilicus (mollusc)
The umbilicus of a shell is the axially aligned, hollow cone-shaped space within the whorls of a coiled mollusc shell. The term umbilicus is often used in descriptions of gastropod shells, i.e. it is a feature present on the ventral (or under) side of many (but not all) snail shells, including some species of sea snails, land snails, and freshwater snails. The word is also applied to the depressed central area on the planispiral coiled shells of ''Nautilus'' species and fossil ammonites. (These are not gastropods, but shelled cephalopods.) In gastropods The spirally coiled whorls of gastropod shells frequently connect to each other by their inner sides, during the natural course of its formation. This results in a more or less solid central axial pillar, known as the columella. The more intimate the contact between the concave side of the whorls is, the more solid the columella becomes. On the other hand, if this connection is less intense, a hollow space inside the whorls may re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spire (mollusc)
A spire is a part of the coiled shell of molluscs. The spire consists of all of the whorls except for the body whorl. Each spire whorl represents a rotation of 360°. A spire is part of the shell of a snail, a gastropod mollusc, a gastropod shell, and also the whorls of the shell in ammonites, which are fossil shelled cephalopods. In textbook illustrations of gastropod shells, the tradition (with a few exceptions) is to show most shells with the spire uppermost on the page. The spire, when it is not damaged or eroded, includes the protoconch (also called the nuclear whorls or the larval shell), and most of the subsequent teleoconch whorls (also called the postnuclear whorls), which gradually increase in area as they are formed. Thus the spire in most gastropods is pointed, the tip being known as the "apex". The word "spire" is used, in an analogy to a church spire or rock spire, a high, thin, pinnacle. The "spire angle" is the angle, as seen from the apex, at which a spire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theba Pisana
''Theba pisana'', common names the white garden snail, sand hill snail, white Italian snail, Mediterranean coastal snail, and simply just the Mediterranean snail, is an edible species of medium-sized, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Helicidae, the typical snails.
