Pholidoteuthidae
''Pholidoteuthis'' is a genus of squid in the monotypic family Pholidoteuthidae, comprising at least two species. The defunct genus ''Tetronychoteuthis'' was previously incorporated into Pholidoteuthidae based upon a singular taxon known as ''Tetronychoteuthis massyae''. Following the discovery of ''Pholidoteuthis boschmai'' in 1950, ''T. massaye'' was placed into ''Pholidoteuthis'', with ''Tetronoychoteuthis'' considered a ''nomen dubium''. ''P. boschmai'' is now considered a junior synonym of '' P. massyae''.O'Shea, S., G. Jackson & K.S. Bolstad 2007. ''Rev. Fish Biol. Fisheries'' 17: 425–435.

Pholidoteuthis Adami
''Pholidoteuthis adami'', sometimes referred to as the Western Atlantic scaled squid or pink scaled squid, is a Deep-sea community, deep-sea species of squid. Description ''Pholidoteuthis adami'' is named in honor of Dr. William Adam (malacologist), W. Adam of Bruxelles, who named the genus ''Pholidoteuthis''. This species was initially Species description, described as an "animal of large to gigantic size; fins a marginal fringe bordering the slender posterior point of the mantle; skin smooth; alternate cups and suckers along the entire length of the tentacular stalk". The initial description relied on 31 Zoological specimen, specimens collected by the USFWS vessel ''Oregon'' in 1950–1956; the holotype (USNM 575139) is a female with a mantle length of , while the other 30 specimens ranged from . A Food and Agriculture Organization document lists a maximum mantle length of . The Mantle (mollusc), mantle of this species is stated to be "thick and soft, wikt:choroid, choroidal", ...

Oegopsida
Oegopsida is one of the four orders of squid in the superorder Decapodiformes, in the class Cephalopoda. Together with the Myopsina, it was formerly considered to be a suborder of the order Teuthida, in which case it was known as Oegopsina. This reclassification is due to Oegopsina and Myopsina not being demonstrated to form a clade. The Oegopsida are an often pelagic squid, with some nerito-oceanic species associated with sea mounts. They consist of 24 families and 69 genera. They have these characters in common: the head is without tentacle pockets, eyes lack a corneal covering, arms and tentacle clubs may have hooks, the buccal supports are without suckers, and oviducts in females are paired. Two families, the Bathyteuthidae and Chtenopterygidae, which have features characteristic of the Myopsida while retaining others common to the Oegopsina, were formerly placed in the family, but are now placed in their own order Bathyteuthida. The Oegopsida differ from the coastal My ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squid
A squid (: squid) is a mollusc with an elongated soft body, large eyes, eight cephalopod limb, arms, and two tentacles in the orders Myopsida, Oegopsida, and Bathyteuthida (though many other molluscs within the broader Neocoleoidea are also called ''squid'' despite not strictly fitting these criteria). Like all other cephalopods, squid have a distinct head, Symmetry (biology)#Bilateral symmetry, bilateral symmetry, and a mantle (mollusc), mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius (cephalopod), gladius or pen, made of chitin. Squid diverged from other cephalopods during the Jurassic and occupy a similar Ecological niche, role to teleost fish as open-water predators of similar size and behaviour. They play an important role in the open-water food web. The two long tentacles are used to grab prey and the eight arms to hold and control it. The beak then cuts the food into suitable size chunks for swal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Adam (malacologist)
William Adam (27 January 1909 – 3 November 1988) was a Dutch–Belgium, Belgian malacologist who specialised in cephalopods. Adam described a number of cuttlefish and bobtail squid species, including ''Euprymna hoylei'', ''Sepia cottoni'', ''Sepia dollfusi'', ''Sepia dubia'', ''Sepia reesi'', ''Sepia sewelli'', ''Sepia thurstoni'', ''Sepia vercoi'', and ''Sepiola knudseni''. Adam was born in The Hague, the son of Constance Jeannette Barkhuijsen and the merchant sailor William Adam. After his schooling in The Hague he visited Java in 1926-27. Upon his return home he studied biology at Utrecht University, obtaining his PhD in 1933 with a dissertation on terrestrial mollusk glands. He then took a position at the Museum of Natural Sciences in Brussels, where he climbed the ranks. In 1952 he became a Belgian citizen. In 1957 Adam became correspondent of the Royal Netherlands Academy of Arts and Sciences. Adam died in Brussels on 3 November 1988 at the age of 79. References ...

Georg Johann Pfeffer
Georg Johann Pfeffer (1854–1931) was a German zoologist, primarily a malacologist, a scientist who studies mollusks. Pfeffer was born in Berlin. In 1887 he became curator of the , which was established in 1843 and destroyed during World War II. Pfeffer's published writings were mainly about cephalopods. The World Register of Marine Species database lists 133 marine Taxon, taxa named by Pfeffer When Pfeffer's name is listed as an authority for a taxon such as the land snail genus ''Lamellaxis'' Hermann Strebel, Strebel & Pfeffer, 1882, his name is ''not'' simply an orthography, orthographic error for the more commonly encountered molluscan authority Pfeiffer, i.e. Ludwig Karl Georg Pfeiffer, who lived 50 years earlier, from 1805 to 1877.

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Nomen Dubium
In binomial nomenclature, a ''nomen dubium'' (Latin for "doubtful name", plural ''nomina dubia'') is a scientific name that is of unknown or doubtful application. Zoology In case of a ''nomen dubium,'' it may be impossible to determine whether a specimen belongs to that group or not. This may happen if the original type series (i. e. holotype, isotype, syntype or paratype) is lost or destroyed. The zoological and botanical codes allow for a new type specimen, or neotype, to be chosen in this case. A name may also be considered a ''nomen dubium'' if its name-bearing type is fragmentary or lacking important diagnostic features (this is often the case for species known only as fossils). To preserve stability of names, the ''International Code of Zoological Nomenclature'' allows a new type specimen, or neotype, to be chosen for a ''nomen dubium'' in this case. 75.5. Replacement of unidentifiable name-bearing type by a neotype. When an author considers that the taxonomic identity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junior Synonym
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The botanical and zoological codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that now goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called '' Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank – for example, the name ''Papilio prorsa'' Linnaeus, ...

Kibibyte
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 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 of 12, 18, 24, 30, 36, 48, or 60 bits, corresponding to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
