Krøyer's Deep Sea Angler Fish
Krøyer's deep sea angler fish (''Ceratias holboelli'') is a species of fish in the family Ceratiidae, the sea devils. This deep-sea anglerfish is found in all oceans, at depths of , but mainly between . Females typically are long, but can reach . The much smaller males only reach and they are symbiotic, as they attach themselves to a female. The species' scientific epithet commemorates Carl Peter Holbøll, a Danish civil servant and early explorer of the fauna of Greenland.

Zoological Museum Of The Zoological Institute Of The Russian Academy Of Sciences
The Zoological Museum of the Zoological Institute of the Russian Academy of Sciences is a Russian museum devoted to zoology. It is located in Saint Petersburg, on Universitetskaya Embankment. It is one of the ten largest nature history museums in the world. Peter the Great's Kunstkamera collections included zoological specimens. In 1724, the museum became a part of the Russian Academy of Sciences. A printed catalogue of the contents was published in 1742. It listed the zoology, botany, geology and anthropology specimens and contained an album of etchings of the building and plan of some of its parts. In 1766, Peter Simon Pallas, a member of the Russian Academy of Sciences, was appointed curator of Zoology. In 1832, the zoological collection was split from the Kunstkamera and, in 1896, moved nearby to its present location in the former southern warehouse of the Saint Petersburg bourse (constructed in 1826-1832). In 1931, the Zoological Institute was established within the Acad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henrik Nikolai Krøyer
Henrik Nikolai Krøyer (22 March 1799 – 14 November 1870) was a Denmark, Danish zoologist. Born in Copenhagen, he was a brother of the composer Hans Ernst Krøyer. He started studying medicine at the University of Copenhagen in 1817, which he later changed to history and philology. While a student, he was a supporter of the Philhellenism, Philhellenic movement, and he participated as a volunteer in the Greek War of Independence along with several fellow students. Upon his return to Denmark, Krøyer gained an interest in zoology. In 1827, he took the position as assistant teacher in Stavanger, where he met, and later married, Bertha Cecilie Gjesdal. Bertha's sister, Ellen Cecilie Gjesdal, was deemed unfit to bring up her child, so Henrik and Bertha adopted the boy, who took on the name Peder Severin Krøyer, and later became a well-known painter. Krøyer returned to Copenhagen in 1830 where he was employed as a teacher in natural history at the Military Academy. As the course l ...

Ceratiidae
Sea devils are the family of deep-sea anglerfish known as the Ceratiidae, from the Greek ''keras'', "horn", referring to the bioluminescent lure that projects from the fishes' forehead. They are among the most widespread of the anglerfishes, found in all oceans from the tropics to the Antarctic. They are large and elongated: females of the largest species, Krøyer's deep sea angler fish, ''Ceratias holboelli'', reach in length. Males, by contrast, are much smaller, reaching , and, like other anglerfishes, spend much of their lives attached to a female after a free-living adolescent stage in which they are very small – at most – and have sharp, beak-like, toothless jaws. One or more males attach themselves permanently to a female, eventually merging circulatory systems. As this genetic chimera matures, the male grows large testicles, while the rest of its body atrophies. Ceratiidae are the only creatures known to become chimeras as a normal part of their lifecycle Life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symbiotic
Symbiosis (from Greek , , "living together", from , , "together", and , bíōsis, "living") is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic. The organisms, each termed a symbiont, must be of different species. In 1879, Heinrich Anton de Bary defined it as "the living together of unlike organisms". The term was subject to a century-long debate about whether it should specifically denote mutualism, as in lichens. Biologists have now abandoned that restriction. Symbiosis can be obligatory, which means that one or more of the symbionts depend on each other for survival, or facultative (optional), when they can generally live independently. Symbiosis is also classified by physical attachment. When symbionts form a single body it is called conjunctive symbiosis, while all other arrangements are called disjunctive symbiosis."symbiosis."

Carl Peter Holbøll
Carl Peter Holbøll (1795–1856) was an officer in the Danish Royal Navy, Greenland colonial officer and explorer of the Greenlandic fauna. Holbøll served as Royal Inspector of Colonies and Whaling in North Greenland (1825–1828), then Inspector of South Greenland (1828–1856). While in this post he became interested in natural history. His main contribution was to send large amounts of faunistic collections to the zoologists in Copenhagen. For example, professor Johannes Theodor Reinhardt described the North American form of the red-necked grebe and named it ''Podiceps holboellii'' (now ''Podiceps grisegena holboellii''). Holbøll himself also wrote a treatise on Greenlandic birds.Ornithologischer Beitrag zur Fauna Grönlands' von Carl Holböll, übersetzt und mit einem Anhang versehen von J.H. Paulsen. Leipzig, Ernst Fleischer. 1846. In the paper, he described the hoary redpoll (''Linota hornemanni'', now known as ''Carduelis hornemanni''), which he named for the botan ...

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 ...

Fauna
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is '' funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenland
Greenland ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark. It is located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland is the world's largest island. It is one of three constituent countries that form the Kingdom of Denmark, along with Denmark and the Faroe Islands; the citizens of these countries are all citizens of Denmark and the European Union. Greenland's capital is Nuuk. Though a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers) for more than a millennium, beginning in 986.The Fate of Greenland's Vikings , by Dale Mackenzie Brown, ''Archaeological Institute of America'', ...

Sperm Whale
The sperm whale or cachalot (''Physeter macrocephalus'') is the largest of the toothed whales and the largest toothed predator. It is the only living member of the genus ''Physeter'' and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus ''Kogia''. The sperm whale is a pelagic mammal with a worldwide range, and will migrate seasonally for feeding and breeding. Females and young males live together in groups, while mature males (bulls) live solitary lives outside of the mating season. The females cooperate to protect and nurse their young. Females give birth every four to twenty years, and care for the calves for more than a decade. A mature sperm whale has few natural predators, although calves and weakened adults are sometimes killed by pods of killer whales (orcas). Mature males average in length, with the head representing up to one-third of the animal's length. Plunging to , it is the third deep ...

Antarctic
The Antarctic ( or , American English also or ; commonly ) is a polar region around Earth's South Pole, opposite the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica, the Kerguelen Plateau and other island territories located on the Antarctic Plate or south of the Antarctic Convergence. The Antarctic region includes the ice shelves, waters, and all the island territories in the Southern Ocean situated south of the Antarctic Convergence, a zone approximately wide varying in latitude seasonally. The region covers some 20 percent of the Southern Hemisphere, of which 5.5 percent (14 million km2) is the surface area of the Antarctica continent itself. All of the land and ice shelves south of 60°S latitude are administered under the Antarctic Treaty System. Biogeographically, the Antarctic realm is one of eight biogeographic realms of Earth's land surface. Geography As defined by the Antarctic Treaty System, the Antarctic r ...

Deep Sea Fish
Deep-sea fish are fish that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep sea fishes include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, viperfish, and some species of eelpout. Only about 2% of known marine species inhabit the pelagic environment. This means that they live in the water column as opposed to the benthic organisms that live in or on the sea floor. Deep-sea organisms generally inhabit bathypelagic (1000–4000m deep) and abyssopelagic (4000–6000m deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic (200–1000m deep) zone as well. The mesopelagic zone is the disphotic zone, meaning light there is minimal but still measurable. The oxygen minimum layer exists somewhere between a depth of 700m and 1000m deep depending on the place in the ocean. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
