Flying Squid
Ommastrephidae is a family of squid containing three subfamilies, 11 genera, and over 20 species. They are widely distributed globally and are extensively fished for food. One species, ''Todarodes pacificus'', comprises around half of the world's cephalopod catch annually. Some members of Ommastrephidae ( volplaning species) are known to have the ability to glide out of water, earning them the common name of "flying squid".

Ommastrephes Bartramii (Neon Flying Squid), Northern Hawaiian Waters
The neon flying squid (''Ommastrephes bartramii''), sometimes called the red flying squid, akaika, and red squid is a species of large flying squid in the family Ommastrephidae. They are found in subtropical and temperate oceanic waters globally. The genus contains bioluminescent species. Taxonomy ''Ommastrephes bartramii'' belongs to the family Ommastrephidae, subfamily Ommastrephinae. It was first described by the French naturalist, explorer, and artist Charles Alexandre Lesueur in 1821. Russian taxonomists consider the separate spawning populations of ''Ommastrephes bartramii'' as subspecies. It was thought that ''Ommastrephes bartramii'' was the only species belonging to the monospecific genus ''Ommastrephes'', but a 2020 study which used mitochondrial DNA to evaluate individuals across nearly the entire distributional range revealed that the genus is actually an allopatric cryptic species complex with four distinct species consistently identified. As a result of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gladius (cephalopod)
The gladius (plural: ''gladii''), or pen, is a hard internal bodypart found in many cephalopods of the superorder Decapodiformes (particularly squids) and in a single extant member of the Octopodiformes, the vampire squid (''Vampyroteuthis infernalis''). It is so named for its superficial resemblance to the Roman short sword of the same name, and is a vestige of the ancestral mollusc shell, which was external. The gladius is located dorsally within the mantle and usually extends for its entire length. Composed primarily of chitin, it lies within the shell sac, which is responsible for its secretion. Gladii are known from a number of extinct cephalopod groups, including teudopseids (''e.g.'' '' Actinosepia'', '' Glyphiteuthis'', '' Muensterella'', '' Palaeololigo'', '' Teudopsinia'', ''Teudopsis'', and ''Trachyteuthis''), loligosepiids (''e.g.'' '' Geopeltis'', '' Jeletzkyteuthis'', and '' Loligosepia''), and prototeuthids (''e.g.'' ''Dorateuthis'', '' Paraplesioteuthis'', ...

Danish People
Danes ( da, danskere, ) are a North Germanic ethnic group and nationality native to Denmark and a modern nation identified with the country of Denmark. This connection may be ancestral, legal, historical, or cultural. Danes generally regard themselves as a nationality and reserve the word "ethnic" for the description of recent immigrants, sometimes referred to as "new Danes". The contemporary Danish national identity is based on the idea of "Danishness", which is founded on principles formed through historical cultural connections and is typically not based on racial heritage. History Early history Denmark has been inhabited by various Germanic peoples since ancient times, including the Angles, Cimbri, Jutes, Herules, Teutones and others. The first mentions of " Danes" are recorded in the mid-6th century by historians Procopius ( el, δάνοι) and Jordanes (''danī''), who both refer to a tribe related to the Suetidi inhabiting the peninsula of Jutland, the province of Sc ...

Martialia Hyadesii
''Martialia hyadesii'' is a species of flying squid commonly known as the sevenstar flying squid. Distribution ''M. hyadesii'' occurs in epipelagic and mesopelagic waters of the Southern Ocean. Its range may be circumpolar with a Sub-Antarctic distribution. Ecology These large squid are known to prey upon deep-sea ridgeheads and other mesopelagic fish, and to be preyed upon in turn by king penguin The king penguin (''Aptenodytes patagonicus'') is the second largest species of penguin, smaller, but somewhat similar in appearance to the emperor penguin. There are two subspecies: ''A. p. patagonicus'' and ''A. p. halli''; ''patagonicus'' ...s and albatrosses.

Neritic
The neritic zone (or sublittoral zone) is the relatively shallow part of the ocean above the drop-off of the continental shelf, approximately in depth. From the point of view of marine biology it forms a relatively stable and well-illuminated environment for marine life, from plankton up to large fish and corals, while physical oceanography sees it as where the oceanic system interacts with the coast. Definition (marine biology), context, extra terminology In marine biology, the neritic zone, also called coastal waters, the coastal ocean or the sublittoral zone, refers to that zone of the ocean where sunlight reaches the ocean floor, that is, where the water is never so deep as to take it out of the photic zone. It extends from the low tide mark to the edge of the continental shelf, with a relatively shallow depth extending to about 200 meters (660 feet). Above the neritic zone lie the intertidal (or eulittoral) and supralittoral zones; below it the continental slope begin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelagic
The pelagic zone consists of the water column of the open ocean, and can be further divided into regions by depth (as illustrated on the right). The word ''pelagic'' is derived . The pelagic zone can be thought of as an imaginary cylinder or water column between the surface of the sea and the bottom. Conditions in the water column change with depth: pressure increases; temperature and light decrease; salinity, oxygen, micronutrients (such as iron, magnesium and calcium) all change. Marine life is affected by bathymetry (underwater topography) such as the seafloor, shoreline, or a submarine seamount, as well as by proximity to the boundary between the ocean and the atmosphere at the ocean surface, which brings light for photosynthesis, predation from above, and wind stirring up waves and setting currents in motion. The pelagic zone refers to the open, free waters away from the shore, where marine life can swim freely in any direction unhindered by topographical constraints. Th ...

Paralarva
Paralarvae (singular: ''paralarva'') are young cephalopods in the planktonic stages between hatchling and subadult. This stage differs from the larval stage of animals that undergo true metamorphosis. Paralarvae have been observed only in members of the orders Octopoda and Teuthida. The term was first introduced by Richard E. Young and Robert F. Harman in 1988. Paralarvae usually spend an uncertain amount of time in the plankton and then typically descend to an adult habitat in the mesopelagic or bathypelagic zone. Their population abundance is dependent on the variation of mortality rates during the planktonic period. See also *Larva *Crustacean larvae Crustaceans may pass through a number of larval and immature stages between hatching from their eggs and reaching their adult form. Each of the stages is separated by a moult, in which the hard exoskeleton is shed to allow the animal to grow. The ... References Further reading *Bigelow, Keith A. "Age and growth in par ...

Predator
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and i ...

Hectocotylus
A hectocotylus (plural: ''hectocotyli'') is one of the arms of male cephalopods that is specialized to store and transfer spermatophores to the female. Structurally, hectocotyli are muscular hydrostats. Depending on the species, the male may use it merely as a conduit to the female, analogously to a penis in other animals, or he may wrench it off and present it to the female. The hectocotyl arm was first described in Aristotle's biological works. Although Aristotle knew of its use in mating, he was doubtful that a tentacle could deliver sperm. The name ''hectocotylus'' was devised by Georges Cuvier, who first found one embedded in the mantle of a female argonaut. Supposing it to be a parasitic worm, in 1829 Cuvier gave it a generic name, combining the Greek word for "hundred" and Latin word for "hollow thing". Anatomy Generalized anatomy of squid and octopod hectocotyli: Variability Hectocotyli are shaped in many distinctive ways, and vary considerably between species. The s ...
