Octopoteuthoidea
Octopoteuthoidea is a superfamily of squid in the order Oegopsida. It consists of two small families and three genera: * Superfamily Octopoteuthoidea ** Family Octopoteuthidae *** Genus '' Octopoteuthis'' *** Genus '' Taningia'' ** Family Lepidoteuthidae ''Lepidoteuthis grimaldii'', also known as the Grimaldi scaled squid, is a large squid growing to in mantle length. It is named after the Grimaldi family, reigning house of Monaco. Prince Albert I of Monaco was an amateur teuthologist who pi ... *** Genus '' Lepidoteuthis'' Members of ''Octopoteuthoidea'' are deep-sea squids characterized by robust bodies and relatively short arms compared to other squids. Many species exhibit bioluminescence, which they use for camouflage and communication in the deep ocean. Notably, ''Taningia danae'' can reach mantle lengths of up to 2 meters and produces powerful bioluminescent displays using photophores on its arms, potentially to stun prey or signal conspecifics.

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] |
Octopoteuthidae
The Octopoteuthidae are a family of squid comprising two genera. The family is characterized by tentacles which cease to grow after the paralarval stage which leads to the adult having eight arms; thus, members of this family are commonly named as octopus squids. Description Octopoteuthidae is considered to be closely related to the monotypic family Lepidoteuthidae (genus '' Lepidoteuthis''), sometimes being its sister family. Octopus squids are characterized by a semi-gelatinous body, with very long, broad fins; the fins approach the length of the mantle in adults. These are oval in shape and muscular, with the two fins being fused towards the midline of the mantle. Their namesake feature is the lack of tentacles in adults; paralarvae and young juveniles possess them, but they do not develop after this stage, and so the adults only have eight arms like an octopus; these arms are armed with hooks. They do not have a hectocotylus; rather, they have a "penis" or terminal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidoteuthidae
''Lepidoteuthis grimaldii'', also known as the Grimaldi scaled squid, is a large squid growing to in mantle length. It is named after the Grimaldi family, reigning house of Monaco. Prince Albert I of Monaco was an amateur teuthologist who pioneered the study of deep sea squids by collecting the 'precious regurgitations' of sperm whales. The Grimaldi scaled squid was first collected from the stomach contents of a sperm whale.Albert 1er of Monaco. "Notes sur un Cachalot." ''Bulletin du Muséum d’histoire naturelle'' 1895, no. 8. It is a widely distributed species in tropical and subtropical areas of the North and South Atlantic, the southern Indian Ocean and the Pacific Ocean, where it has been recorded off Japan and in the west Pacific.

Octopoteuthis
''Octopoteuthis'' is a genus of squid, one of the two referred to as octopus squid (family Octopoteuthidae), the other being '' Taningia'', its sister genus. Both ''Octopoteuthis'' and ''Taningia'' are characterized by their lack of tentacles for the majority of their life cycle, which led to their common name. Classification This genus is separated from ''Taningia'' by adults possessing spindle-shaped photophores on the tips of all 8 arms (as opposed to a globular pair on a single arm pair in ''Taningia''); the presence of additional photophores embedded in the mantle, head, and arms (the location and sizes of which vary among the species); and a smaller adult size, with mantle lengths (ML) of up to , but typically not exceeding . This genus possesses two rows of arm hooks on each arm pair, which may already be present at 2.5 mm ML. The paralarvae of this genus possess "weak", gelatinous tentacle stalks, the tentacles themselves are lost at about ML. Paired photophores may b ...

Samuel Stillman Berry
Samuel Stillman Berry (March 16, 1887 – April 9, 1984) was an American marine zoologist who specialized in cephalopods. Early life Berry was born in Unity, Maine, but the family home was the Winnecook Ranch in Montana, which had been founded by his father Ralph in 1880. In 1897, he moved with his mother to Redlands, California. Berry received a B.S. (1909) from Stanford and his M.S. (1910) from Harvard. He then returned to Stanford for his Ph.D. work on cephalopods and got his doctorate in 1913. Career From 1913 until 1915, he worked as a librarian and research assistant at the Scripps Institution for Biological Research in La Jolla, California. This was the last paid employment he ever held in academia—all his later studies and expeditions were financed by the profits from the family ranch in Montana. From November 1946 to December 1969, Berry published his own journal, ''Leaflets in Malacology'', which primary contained articles which he had written himself ...

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] |
Taningia
''Taningia'' is a genus of squid, one of the two referred to as octopus squid (family Octopoteuthidae), the other being ''Octopoteuthis'', its sister genus. Both ''Octopoteuthis'' and ''Taningia'' are characterized by their lack of tentacles for the majority of their life cycle, which led to their common name. Classification This genus is named after Danish fisheries biologist Åge Vedel Tåning (1890-1958). ''Taningia'' is separated from ''Octopoteuthis'' by adults possessing a large photophore on the tips of arm pair II (second pair from the dorsal), which are the only known photophores on the body along with the ink sac organ (''Octopoteuthis'' has photophores on each arm-tip and spread around its body). The photophores, around the size of lemons, possesses eyelid-like skin flaps which conceal the light organs when needed. The genus reaches in mantle length ( ML), though has also been reported. This genus possesses two rows of arm hooks on each arm pair, which develop afte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mollusc Superfamilies
Mollusca is a phylum of protostomic invertebrate animals, whose members are known as molluscs or mollusks (). Around 76,000 extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and the proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat, as numerous groups are freshwater and even terrestrial species. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known extant invertebrate sp ...
