Bathypolypus Valdiviae
''Bathypolypus valdiviae'', common name the boxer octopus or Valdivia bathyal octopus, is a species of octopus in the Bathypolypodidae family. It is endemic to the south Atlantic off southern Africa below a depth of 500m where it was one of the most commonly sampled cephalopods, taken mainly from the sea bed. The specific name commemorates the SS Valdivia the steamship used on the Valdivia Expedition of 1898-1899 and which was led by Carl Chun Carl Chun (1 October 1852 – 11 April 1914) was a German marine biologist. Chun was born in Höchst, today a part of Frankfurt, and studied zoology at the University of Leipzig, where from 1878 to 1883 he was privat-docent of zoology and an a ....

Johannes Thiele (zoologist)
Karl Hermann Johannes Thiele (1 October 1860 – 5 August 1935) was a German zoologist specialized in malacology. Thiele was born in Goldap, East Prussia. His ''Handbuch der systematischen Weichtierkunde'' ( English edition published by the Smithsonian under the title ''Handbook of Systematic Malacology'') is a standard work. From 1904 until his retirement in 1925 he was the curator of the malacological collection at the Museum für Naturkunde (Museum of Natural History) in Berlin. Thiele described more than 1.500 new species of molluscs; until today their types are deposited with the Museum of Natural History in Berlin. Especially important are his works on the Mollusca of the First German Antarctica Expedition and of the German Deep Sea Expedition aboard the vessel Valdivia. Thiele's classification of Gastropoda has been in use up to the past decade. It modified an earlier concept of Henri Milne-Edwards (1848) with three subclasses: Prosobranchia, Opisthobranchia and Pulmon ...

Carl Chun
Carl Chun (1 October 1852 – 11 April 1914) was a German marine biologist. Chun was born in Höchst, today a part of Frankfurt, and studied zoology at the University of Leipzig, where from 1878 to 1883 he was privat-docent of zoology and an assistant to Rudolf Leuckart. After professorial posts in Königsberg (1883–1891) and Breslau (1891–1898), he returned to Leipzig as a professor of zoology.UNI Leipzig Professorenkatalog (biographical sketch) In 1888, Chun described seasonal vertical migration (SVM) which has a periodicity of ca. 1 year.

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List ...

Sea Life Base
The sea, connected as the world ocean or simply the ocean, is the body of salty water that covers approximately 71% of the Earth's surface. The word sea is also used to denote second-order sections of the sea, such as the Mediterranean Sea, as well as certain large, entirely landlocked, saltwater lakes, such as the Caspian Sea. The sea moderates Earth's climate and has important roles in the water, carbon, and nitrogen cycles. Humans harnessing and studying the sea have been recorded since ancient times, and evidenced well into prehistory, while its modern scientific study is called oceanography. The most abundant solid dissolved in seawater is sodium chloride. The water also contains salts of magnesium, calcium, potassium, and mercury, amongst many other elements, some in minute concentrations. Salinity varies widely, being lower near the surface and the mouths of large rivers and higher in the depths of the ocean; however, the relative proportions of dissolved salts vary ...

Octopus
An octopus ( : octopuses or octopodes, see below for variants) is a soft-bodied, eight- limbed mollusc of the order Octopoda (, ). The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, an octopus is bilaterally symmetric with two eyes and a beaked mouth at the center point of the eight limbs. The soft body can radically alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight appendages behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse of all invertebrates. Octopuses inhabit various regions of the ocean, including coral reefs, pelagic waters, and the seabed; some live in the intertidal zone and others at abyssal depths. Most species grow quickly, mature earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SS Valdivia (1886)
SS ''Valdivia'' was a passenger ship that was built in England and launched in 1886 as ''Tijuca''. She was renamed ''Valdivia'' in 1896, ''Tom G Corpi'' in 1908 and ''Flandre'' in 1909. She had a succession of German owners until 1909, when she was bought by a French shipping company. She was scrapped in 1927. ''Valdivia'' is notable as the ship in which the German marine biologist Carl Chun undertook the Valdivia Expedition in 1898–99. Building Armstrong, Mitchell & Co built ''Tijuca'' in its shipyard at Low Walker as yard number 496 for Hamburg Südamerikanische DG. She was launched in 28 August 1886 and completed that October. Her registered length was , her beam was and her depth was . She had berths for 40 first class and 280 steerage class passengers, and her tonnages were and . The Wallsend Slipway & Engineering Company built her three-cylinder triple-expansion engine, which was rated at 265 NHP. Throughout her German ownership, the ship was registered in Ha ...

Valdivia Expedition
The ''Valdivia'' Expedition, or ''Deutsche Tiefsee-Expedition'' (German Deep Sea Expedition), was a scientific expedition organised and funded by the German Empire under Kaiser Wilhelm II and was named after the ship which was bought and outfitted for the expedition, the SS ''Valdivia''. It was led by the marine biologist Carl Chun and the expedition ran from 1898-1899 with the purpose of exploring the depths of the oceans below 500 fathoms, which had not been explored by the earlier Challenger Expedition. The Challenger Expedition was the expedition that established modern Oceanography, prompting many other expeditions, nationally or privately funded, which would dredge the deep-sea in search of new and exotic species. This late 19th Century fascination with organisms found at great depths was unsurprising, because in the mid-19th century most scientists followed Abyssus theory which stated that it was not possible for life to exist below 300 fathoms depth.
