Architeuthoidea

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] |

Superfamily (biology)
In biology, taxonomic rank (which some authors prefer to call nomenclatural rank because ranking is part of nomenclature rather than taxonomy proper, according to some definitions of these terms) is the relative or absolute level of a group of organisms (a ''taxon'') in a hierarchy that reflects evolutionary relationships. Thus, the most inclusive clades (such as Eukarya and Animalia) have the highest ranks, whereas the least inclusive ones (such as ''Homo sapiens'' or '' Bufo bufo'') have the lowest ranks. Ranks can be either relative and be denoted by an indented taxonomy in which the level of indentation reflects the rank, or absolute, in which various terms, such as species, genus, family, order, class, phylum, kingdom, and domain designate rank. This page emphasizes absolute ranks and the rank-based codes (the Zoological Code, the Botanical Code, the Code for Cultivated Plants, the Prokaryotic Code, and thCode for Viruses require them. However, absolute ranks are not r ... [...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] |
Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of Genus, genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical o ...

Alluroteuthis
The Antarctic neosquid (''Alluroteuthis antarcticus'') is the only neosquid in the genus ''Alluroteuthis''. The tentacles are relatively short compared to the arms. Nils Hjalmar Odhner, discoverer of the species, suggested that '' Parateuthis tunicata'', discovered by Johannes Thiele in 1920, might be a young Antarctic neosquid. The validity of this suggestion is still in question. The name is derived from its habitat in the Antarctic Ocean. Distribution ''Alluroteuthis antarcticus'' occurs in from depths of 0–2,800 m (epipelagic and mesopelagic waters), and paralarvae can be found in the upper 200 m (epipelagic waters). Its range may be circumpolar with an Antarctic and Sub-Antarctic distribution. Ecology It preys upon Antarctic krill, Antarctic silverfish and other squids. However, Isotopic evidence suggests a diet in prey that are likely mesopelagic zooplankton Zooplankton are the heterotrophic component of the planktonic community (the " zoo-" prefix comes ...

Neoteuthis
''Neoteuthis'' is a monotypic genus of squid whose sole member is ''Neoteuthis thielei'', from the family Neoteuthidae. This species has long tentacular clubs measuring 60% of the mantle length and fins which are 70% of its mantle length. It has a proximal locking-apparatus for the club which is restricted to manus, which in turn has proximal suckers which are circular. It has been recorded from the South Atlantic Ocean, North Atlantic Ocean, near the Canary Islands and North Pacific Ocean, north of Hawaii. The paralarvae and juveniles are found in the epipelagic to mesopelagic zones while adults occur in the mesopelagic to bathypelagic The bathypelagic zone or bathyal zone (from Greek βαθύς (bathýs), deep) is the part of the open ocean that extends from a depth of below the ocean surface. It lies between the mesopelagic above and the abyssopelagic below. The bathypela ... zones. References Neoteuthidae Cephalopods described in 1921 Monotypic cephalopod gener ...
