Jacques Pellegrin
Jacques Pellegrin (12 June 1873, Paris – 12 August 1944) was a French zoologist. In Paris, he worked under zoologist Léon Vaillant (chair of reptiles and fishes) at the ''Muséum national d'histoire naturelle''. From 1897, Pellegrin served as ''préparateur'' at the museum. He obtained doctorates in medicine (1899) and science (1904), and in 1908 was named as an assistant director. After many missions abroad, he became sub-director of the museum in 1937, and replaced Louis Roule (1861–1942) as the chairperson of herpetology and ichthyology. He published over 600 scientific books and articles and discovered around 350 new species. He named a number of fishes from the family Cichlidae, such as the genera '' Astatoreochromis'', '' Astatotilapia'', '' Boulengerochromis'', ''Lepidiolamprologus'', ''Nanochromis'' and '' Ophthalmotilapia''. Taxa named in his honor He has the following species named in his honor: * The Clingfish '' Apletodon pellegrini'' * ''Enteromius pelle ...

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Astatotilapia
''Astatotilapia'' is a genus of small freshwater fish in the family Cichlidae found in Eastern and Northern Africa, with a single species, ''A. flaviijosephi'', in Western Asia (the only non-African haplochromine). Many species have been moved between this genus and ''Haplochromis'', and while some consensus has been reached in recent years, their mutual delimitation is still far from settled. Based on mtDNA, ''Astatotilapia'' as currently defined is polyphyletic.Genner; Ngatunga; Mzighani; Smith; and Turner (2015). Geographical ancestry of Lake Malawi’s cichlid fish diversity. Biol. Lett. 11: 2015023. Species There are currently 10 recognized species in this genus: * ''Astatotilapia bloyeti'' ( Sauvage, 1883) (Bloyet's haplo) * ''Astatotilapia burtoni'' ( Günther, 1894) * ''Astatotilapia calliptera'' ( Günther, 1894) (Eastern happy) * ''Astatotilapia desfontainii'' ( Lacépède, 1802) * ''Astatotilapia flaviijosephi'' ( Lortet, 1883) (Jordan mouthbrooder) * ''Astatotilapia ...

MG42
The MG 42 (shortened from German: ''Maschinengewehr 42'', or "machine gun 42") is a German recoil-operated air-cooled general-purpose machine gun used extensively by the Wehrmacht and the Waffen-SS during the second half of World War II. Entering production in 1942, it was intended to supplement and replace the earlier MG 34, which was more expensive and took much longer to produce, but both weapons were produced until the end of World War II. Designed to use the standard German 7.92×57mm Mauser rifle round, be low-cost and easier to mass-produce, the MG 42 proved to be highly reliable and easy to operate. It is most notable for its very high cyclic rate for a gun using full-power service cartridges, averaging about 1,200 rounds per minute compared to around 850 for the MG 34, and 450 to 600 for other common machine guns like the M1919 Browning, FM 24/29 or Bren gun. This ability made it extremely effective in providing suppressive fire, and its unique sound led to it being nick ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wehrmacht
The ''Wehrmacht'' (, ) were the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the ''Heer'' (army), the ''Kriegsmarine'' (navy) and the ''Luftwaffe'' (air force). The designation "''Wehrmacht''" replaced the previously used term and was the manifestation of the Nazi regime's efforts to rearm Germany to a greater extent than the Treaty of Versailles permitted. After the Nazi rise to power in 1933, one of Adolf Hitler's most overt and audacious moves was to establish the ''Wehrmacht'', a modern offensively-capable armed force, fulfilling the Nazi régime's long-term goals of regaining lost territory as well as gaining new territory and dominating its neighbours. This required the reinstatement of conscription and massive investment and defense spending on the arms industry. The ''Wehrmacht'' formed the heart of Germany's politico-military power. In the early part of the Second World War, the ''Wehrmacht'' employed combined arms tactics (close-cover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Tate Regan
Charles Tate Regan FRS (1 February 1878 – 12 January 1943) was a British ichthyologist, working mainly around the beginning of the 20th century. He did extensive work on fish classification schemes. Born in Sherborne, Dorset, he was educated at Derby School and Queens' College, Cambridge and in 1901 joined the staff of the Natural History Museum, where he became Keeper of Zoology, and later director of the entire museum, in which role he served from 1927 to 1938. Regan was elected Fellow of the Royal Society in 1917. Regan mentored a number of scientists, among them Ethelwynn Trewavas, who continued his work at the British Natural History Museum. Species Among the species he described is the Siamese fighting fish (''Betta splendens''). In turn, a number of fish species have been named ''regani'' in his honour: *A Thorny Catfish '' Anadoras regani'' (Steindachner, 1908) *The Dwarf Cichlid '' Apistogramma regani'' *'' Apogon regani'' *A Catfish '' Astroblepus regani'' * ...

They are part of a group popularly known as eartheaters and mostly feed by picking up mouthfuls of sediment to sift out food items such as invertebrates, plant material and detritus. The largest species reach up to in standard length. They are often kept in aquariums. As an invasive species Geophagus Surinamensis was an invasive species in Malaysia, recently found in Putrajaya, the populations are now controlled by giant snakeheads.
