Carenzia Carinata
''Carenzia carinata'' is a species of sea snail, a marine gastropod mollusk in the family Seguenziidae. Description The size of the shell varies between 2.7 mm and 4.4 mm. The shell thin, transparent, glossy, but not nacreous forms a depressed cone. Its color is glassy. The shell is umbilicated and rather smooth. The sculpture of the shell shows a single, sharp keel round the periphery, showing at the base of the spire-whorls. The shell has a thread-like spiral rib below the rather deep suture of each whorl (varying in position), numerous but slight flexuous striae below the rib, and in some specimens minute close-set curved longitudinal striae on the upper whorls. The base is nearly smooth or marked only with microscopic lines of growth. The seven whorls of the short spire are compressed, slightly shouldered by the infrasutural rib. The body whorl is disproportionally large, and the first is globular. The narrow aperture is rhomboidal, angulated in the middle by th ...

John Gwyn Jeffreys
John Gwyn Jeffreys FRS (18 January 1809 – 21 January 1885) was a British conchologist and malacologist. Biography John Gwyn Jeffreys was born on 18 January 1809, at Swansea, Wales. He was the eldest son of J. Jeffreys of Fynone, Glamorgan. Jeffreys was educated in Swansea at the Bishop Gore School (Swansea Grammar School). From the age of seventeen, he was an apprentice to one of the principal solicitors of Swansea, before going to London, where he qualified as a barrister in 1838. Jeffreys worked as a solicitor in Swansea until 1856, when he was called to the bar in London. But his greater passion was for conchology. He was not satisfied simply to form a collection, but was interested in all aspects of the biology of molluscs. On 2 April 1840 he became a Fellow of the Royal Society. On 21 June that year he married Ann Nevill at Llangennech. They had a son and four daughters; and were the grandparents of the physicist, Henry Gwyn Jeffreys Moseley. In 1866 Jeffreys ret ...

Lip (gastropod)
In the shell of gastropod mollusks (a snail shell), the lip is the free margin of the peristome (synonym: peritreme) or aperture (the opening) of the gastropod shell. In dextral (right-handed) shells (most snail shells are right-handed), the right side or outer side of the aperture is known as the outer lip (''labrum''). The left side of the aperture is known as the inner lip or columellar lip (''labium'') if there is a pronounced lip there. In those species where there is no pronounced lip, the part of the body whorl that adjoins the aperture is known as the parietal wall. The outer lip is usually thin and sharp in immature shells, and in some adults (e.g. the land snails '' Helicella'' and ''Bulimulus''). However, in some other land snails and in many marine species the outer lip is ''thickened'' (also called ''callused''), or ''reflected'' (turned outwards). In some other marine species it is curled inwards (''inflected''), as in the cowries such as '' Cypraea''. It can also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molluscs Of Brazil
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 gastropod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gastropods Described In 1877
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, Scramble for Africa, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
