Taoniinae
Taoniinae is a subfamily containing ten genera of glass squids. Description Unlike Cranchiinae , the other subfamily within Cranchiidae , Taoniinae all lack cartilaginous strips which extend back from the funnel-mantle point of fusion. Their funnels are free laterally, and they have one to three photophores on the eyes. The largest photophore is crescent-shaped for most genera, but it's triangular in '' Helicocranchia'', a semicircle in '' Bathothauma'', and circular in '' Sandalops''. This is in contrast to glass squids in the subfamily Cranchiinae, which have at least four small photophores which are round or oval in shape. In addition, males lack hectocotyli; these are arms which have evolved to specialize in storage and transfer of spermatophores to females. Taoniinae are also often larger than Cranchiinae and have darker beaks. Another characteristic is that a Taoniinae's caecum, is smaller than its stomach; in Cranchiinae, the caecum is larger than the stomach. Taxono ...

Cranchiidae
The family Cranchiidae comprises the approximately 60 species of glass squid, also known as cockatoo squid, cranchiid, cranch squid, or bathyscaphoid squid. Cranchiid squid occur in surface and midwater depths of open oceans around the world. They range in mantle length from to over , in the case of the colossal squid. The common name, glass squid, derives from the transparent nature of most species. Cranchiid squid spend much of their lives in partially sunlit shallow waters, where their transparency provides camouflage. They are characterised by a swollen body and short arms, which bear two rows of suckers or hooks. The third arm pair is often enlarged. Many species are bioluminescent organisms and possess light organs on the undersides of their eyes, used to cancel their shadows. Eye morphology varies widely, ranging from large and circular to telescopic and stalked. A large, fluid-filled chamber containing ammonia solution is used to aid buoyancy. This buoyancy system is uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass Squid

Teuthowenia
''Teuthowenia'' is a genus of glass squid in the subfamily Taoniinae. Members of this genus are characterized by their deep-sea habitat, clear bodies, and ability to engorge themselves with water to become larger when threatened. Each known species has a visible digestive gland, which serves a similar purpose as a stomach and liver The liver is a major Organ (anatomy), organ only found in vertebrates which performs many essential biological functions such as detoxification of the organism, and the Protein biosynthesis, synthesis of proteins and biochemicals necessary for .... The genus contains bioluminescent species. It includes three species: *'' Teuthowenia maculata'' (Leach, 1817) - found in the tropical waters of the eastern Atlantic Ocean. *'' Teuthowenia megalops'' (Prosch, 1849) - found in the subarctic, temperate, and (rarely) subtropical waters of the northern Atlantic Ocean. *'' Teuthowenia pellucida'' (Chun, 1910) - found throughout the oceans of the southern ...

Sandalops Melancholicus
''Sandalops melancholicus'', the sandal-eyed squid or melancholy cranch squid, is a small species of glass squid. It is known to reach a mantle length of 11 cm. It is distributed in the tropical and subtropical oceans around the world. It is the only species in the genus ''Sandalops'' but some authorities suggest that this may be a species complex rather than a monotypic genus. Description ''Sandalops melancholicus'' is a small squid which grows to a mantle length of 110mm. There are only suckers on the tentacular clubs with a further two series of suckers and pads on distal half of the stalk of the tentacles. It does not possess a funnel valve and the funnel organ has a distal pad and two large triangle shaped flaps. It has short, round fins with the posterior end of the gladius protruding between them. Like ''Liguriella'', but not in any other Taoniinae, it has two contiguous photophores on its eye, a large one and a small one, and it does not have any photophores o ...

Galiteuthis
''Galiteuthis'' is a genus of glass squids from the family Cranchiidae and the subfamily Taoniinae. Squids in the genus ''Galiteuthis'' are large squids with mantle lengths measuring up to 660mm, although it has been suggested that mantle length could reach as much as 2.7m. The most distinctive feature of the speciesa in this genus are they have hooks on the tentacular clubs while there are no hooks on the arms, and by their long, thin, terminal fins. The genus contains bioluminescent species. Species Five species are currently recognised: *'' Galiteuthis armata'' Joubin, 1898 *''Galiteuthis glacialis'' (Chun, 1906) *'' Galiteuthis pacifica'' ( Robson, 1948) *''Galiteuthis phyllura'' Berry A berry is a small, pulpy, and often edible fruit.

Junior Synonym
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, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia lev ...

Pteromalidae
The Pteromalidae are a very large family of mostly parasitoid wasps, with some 3,450 described species in about 640 genera (the number was greater, but many species and genera have been reduced by synonymy in recent years). The subfamily-level divisions of the family are highly contentious and unstable, and the family is thought to be "artificial", composed of numerous, distantly related groups (polyphyletic). Accordingly, details of their life histories range over nearly the entire range possible within the Chalcidoidea, though the majority are (as with most chalcidoids) parasitoids of other insects. They are found throughout the world in virtually all habitats, and many are important as biological control agents. The oldest known fossil is known from the Early Cretaceous. In essence, a "pteromalid" is any member of the Chalcidoidea that has five-segmented tarsi and does not have the defining features of any of the remaining families with five-segmented tarsi. It is highly prob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junior Homonym
In biology, a homonym is a name for a taxon that is identical in spelling to another such name, that belongs to a different taxon. The rule in the International Code of Zoological Nomenclature is that the first such name to be published is the senior homonym and is to be used (it is " valid"); any others are junior homonyms and must be replaced with new names. It is, however, possible that if a senior homonym is archaic, and not in "prevailing usage," it may be declared a ''nomen oblitum'' and rendered unavailable, while the junior homonym is preserved as a ''nomen protectum''. :For example: :* Cuvier proposed the genus ''Echidna'' in 1797 for the spiny anteater. :*However, Forster had already published the name ''Echidna'' in 1777 for a genus of moray eels. :*Forster's use thus has priority, with Cuvier's being a junior homonym. :*Illiger published the replacement name ''Tachyglossus'' in 1811. Similarly, the International Code of Nomenclature for algae, fungi, and plants (I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.
