Arthur Erskine Ellis
Arthur Erskine Ellis (1 October 1902 – 28 February 1983), often known as A.E. Ellis, was a British scientist, biologist and naturalist. Ellis is best known for his large number of malacological publications, including some which became essential texts on the subject of British non-marine malacology. To a lesser extent, Ellis published papers about other land invertebrates and various aspects of the fauna and flora of Britain. In addition Ellis had five ghost stories published. Ellis was also a plant collector. From 1919 to 1961 he contributed specimens of spermatophytes to a number of different herbariums in Britain. Stella Turk, the British naturalist said about Ellis, "It is difficult to categorise people. Should one even try? We are all multiple in a singular way!"; she also commented, "As might have been expected, he wrote his own obituary in which he gives a broad outline of his life and very lengthy bibliography", ( J. Conch. 31 1983).Stella Turk, "Stella Turk write ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bangalore
Bangalore (), officially Bengaluru (), is the capital and largest city of the Indian state of Karnataka. It has a population of more than and a metropolitan population of around , making it the third most populous city and fifth most populous urban agglomeration in India, as well as the largest city in South India, and the 27th largest city in the world. Located on the Deccan Plateau, at a height of over above sea level, Bangalore has a pleasant climate throughout the year, with its parks and green spaces earning it the reputation as the "Garden City" of India. Its elevation is the highest among the major cities of India. An aerospace, heavy engineering and electronics hub since the 1960s, Bangalore is widely regarded as the "Silicon Valley of India" because of its role as the nation's leading information technology (IT) exporter.——— In the Ease of Living Index 2020 (published by the Ministry of Housing and Urban Affairs), it was ranked the most livable Indian ...

Freshwater Clam
Freshwater bivalves are one kind of freshwater mollusc, along with freshwater snails. They are bivalves that live in fresh water as opposed to salt water, which is the main habitat type for bivalves. The majority of species of bivalve molluscs live in the sea, but in addition, a number of different families live in fresh water (and in some cases, also in brackish water). These families belong to two different evolutionary lineages (freshwater mussels and freshwater clams), and the two groups are not closely related. Freshwater bivalves have a simple morphology that varies among taxa, and are distributed around most regions of the world. Species in the two groups vary greatly in size. Some pea clams (''Pisidium'' species) have an adult size of only 3 mm. In contrast, one of the largest species of freshwater bivalves is the swan mussel, in the family Unionidae; it can grow to a length of 20 cm, and usually lives in lakes or slow rivers. Freshwater pearl mussels are econo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land's End
Land's End ( kw, Penn an Wlas or ''Pedn an Wlas'') is a headland and tourist and holiday complex in western Cornwall, England, on the Penwith peninsula about west-south-west of Penzance at the western end of the A30 road. To the east of it is the English Channel, and to the west the Celtic Sea. Land's End is the most westerly point of mainland England. However, it is not the westernmost point on mainland Great Britain, as this title narrowly goes to Corrachadh Mòr in the Scottish Highlands. Geography The actual Land's End, or Peal Point, is a modest headland compared with nearby headlands such as Pedn-men-dhu overlooking Sennen Cove and Pordenack, to the south. The present hotel and tourist complex is at Carn Kez, south of the actual Land's End. Land's End has a particular resonance because it is often used to suggest distance. Land's End to John o' Groats in Scotland is a distance of by road and this ''Land's End to John o' Groats'' distance is often used to define chari ...

Helix Draparnaudi
A helix () is a shape like a corkscrew or spiral staircase. It is a type of smooth space curve with tangent lines at a constant angle to a fixed axis. Helices are important in biology, as the DNA molecule is formed as two intertwined helices, and many proteins have helical substructures, known as alpha helices. The word ''helix'' comes from the Greek word ''ἕλιξ'', "twisted, curved". A "filled-in" helix – for example, a "spiral" (helical) ramp – is a surface called ''helicoid''. Properties and types The ''pitch'' of a helix is the height of one complete helix turn, measured parallel to the axis of the helix. A double helix consists of two (typically congruent) helices with the same axis, differing by a translation along the axis. A circular helix (i.e. one with constant radius) has constant band curvature and constant torsion. A ''conic helix'', also known as a ''conic spiral'', may be defined as a spiral on a conic surface, with the distance to the apex an expo ...

Helicidae
Helicidae is a large, diverse family of small to large, air-breathing land snails, sometimes called the "typical snails." A number of species in this family are valued as food items, including ''Cornu aspersum'' (formerly ''Helix aspersa'') the brown or garden snail, and ''Helix pomatia'' the "escargot". The biologies of these two species in particular have been thoroughly studied and documented. Shell description The shells of these snails are mostly rather globular in shape. In some genera, such as ''Cepaea'', the shells are brightly colored and patterned. Anatomy The animal is capable of complete retraction within the shell. The tail is without a mucous gland or projection. Tryon G. W. 1887 ''Manual of conchology; structural and systematic. With illustrations of the species''. Second series: PulmonataVolume 3 Helicidae - Volume I. pag34.
