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.

Cephalopod Genera
A cephalopod is any member of the molluscan class Cephalopoda (Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology. Cephalopods became dominant during the Ordovician period, represented by primitive nautiloids. The class now contains two, only distantly related, extant subclasses: Coleoidea, which includes octopuses, squid, and cuttlefish; and Nautiloidea, represented by ''Nautilus'' and ''Allonautilus''. In the Coleoidea, the molluscan shell has been internalized or is absent, whereas in the Nautiloidea, the external shell remains. About 800 living species of cephalopods have been ide ...

Mebibyte
The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as The Internet Protocol () refer to an 8-bit byte as an octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the bit endianness. The first bit is number 0, making the eighth bit number 7. The size of the byte has historically been hardware-dependent and no definitive standards existed that mandated the size. Sizes from 1 to 48 bits have been used. The six-bit character code was an often-used implementation in early encoding systems, and computers using six-bit and nine-bit bytes were common in the 1960s. These systems often had memory words ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sasakiopus
''Sasakiopus'' is a genus of octopus containing only one species, ''Sasakiopus salebrosus'', the rough octopus. It is part of the family Enteroctopodidae. Genetic analysis appeared to show that ''S. salebrosus'' is the sister taxon of the genera '' Benthoctopus'' and '' Vulcanoctopus'', although the former is now considered a synonym of '' Bathypolypus'', the only genus in the family Bathypolypodidae, and the latter as a synonym of '' Muusoctopus''. The type specimen was collected and the Sea of Okhotsk, and the describer Madoka Sasaki named it ''Octopus salebrosus'' in 1920. When Guy Coburn Robson revised the Octopodidae, he tentatively reassigned ''O. salebrosus'' to ''Bathypolypus'' based on its rough skin, deep web, and short arms. The only specimens available to Robson were females, so the ligula could not be examined, the ligulae of ''Bathypolypus'' are distinctively large and are laminated. Subsequent workers raised doubts about where this species should be placed until s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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 Pulmonata. ...

Bathypolypus Sponsalis
''Bathypolypus sponsalis'', commonly called the globose octopus, is a deep sea cephalopod that can be found in both the eastern Atlantic Ocean and the Mediterranean Sea. It possesses many morphological traits adapted to a deep sea environment, including large eggs, reduced gills, no ink sac, and subgelatinous tissues. A distinguishing factor are the relatively large reproductive organs. Their diet consists of predominantly crustaceans and molluscs, but they sometimes consume fish as well. ''Bathypolypus sponsalis'' usually dies quickly after reproduction and only spawns once in their lifetime. Sexually mature females have a mantle length of at least 34 mm and sexually mature males have a mantle length of about 24 mm. Juveniles are white and transition to dark brown then to dark purple once maturity is reached. Range and habitat ''Bathypolypus sponsalis'' are found in areas ranging from the eastern Atlantic Ocean all the way to the Mediterranean Sea. They typically resi ...

Bathypolypus Rubrostictus
''Bathypolypus rubrostictus'' is a species of octopus in the family Bathypolypodidae. Only one male specimen has been found. Distribution B. rubrostictus was initially identified from a specimen off the coast of the Ryuku Islands in the South China Sea off the coast of Japan. It inhabits the upper bathyal waters at 350-370 m. Unlike all other species in the genus Bathypolypus, B. rubrostictus lives in the Pacific Ocean, while all the other species in its genus inhabit the Atlantic Ocean. Description This species is 20 mm in mantle length (ML) and its arms are short and stubby (2-2.5 times ML). Its body is covered with small, brown-red spots, and its web is pale reddish-brown. Like most deep-sea octopuses and all species in the genus Bathypolypus, B. rubrostictus lacks an ink sac An ink sac is an anatomical feature that is found in many cephalopod mollusks used to produce the defensive cephalopod ink. With the exception of nocturnal and very deep water cephalopods, all Coleo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ferdinand Victor Alphons Prosch
Ferdinand Victor Alphons Prosch (November 25, 1820 in Copenhagen – July 29, 1885) was a Danish doctor, veterinarian and biologist. Prosch's father, Johannes Henrik William Prosch (died 1843) was a secretary in the Danish War Chancery and his mother, Caroline Sophie (née Brement) was French. In 1837 Prosch was a student at the Metropolitan School in Copenhagen and by 1843 he had taken his medical exams. Between 1843 and 1846 Prosch was employed by the University as a prosector, i.e. a preparer of specimens for dissection in the University's Zoological museum. In 1847 he joined the ''Flaaden'' as the ship's doctor on a voyage to Madeira. Guinea, Venezuela and the Caribbean. In 1848 he was the ship's doctor on the frigate ''Havfrue'' ("Mermaid") in the First Schleswig War. After the war practiced as a doctor in Copenhagen and was a teacher of natural history, in which capacity he published the book "Lærer i Naturhistorie, i hvilken Egenskabin" 1851, which at the time was widely ...
