Taonius
''Taonius'' is a small genus of glass squid. Although it comprises only three recognised species, it has been suggested there may be as many as five species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriat .... ''Taonius borealis'' is found in the North Pacific Ocean and ''Taonius pavo'' is found in the Atlantic and possibly SW Indian Ocean. Some teuthologists dispute Voss's synonymy of ''Belonella'' with ''Taonius''. The genus contains bioluminescent species.

Taonius Belone
''Taonius belone'' is a glass squid belonging to the genus ''Taonius'' from the family Cranchiidae. It occurs in the northern subtropical and in the tropical or equatorial waters of the Pacific and Indian Oceans. Description ''Taonius belone'' is a large species of glass squid, which reaches a mantle length of up to 66 cm, the mantle being rather leathery in texture. It has short arms which have narrow protective membranes which widen near the arm bases where they join up to create an internal umbrella. Each arm has two rows of suckers which become denser towards the tips; there are at least 21 pairs of suckers on each arm, with the largest suckers around the 8th pair. The largest suckers each have 20–30 teeth, wide and tightly set, that cover entire margin of the ring; the smaller distal suckers have only 6–8 teeth while the suckers located near the arm bases have teeth which are merged and present a smooth surface except for few distal undulations.

Taonius Pavo
''Taonius pavo'' is a species of glass squid found in the Atlantic Ocean. Its exact geographic distribution is uncertain, but it may extend to the southwestern Indian Ocean through the Agulhas Current. They are eaten by the 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 famil ... in Southeast Asia, southern Australian, Hawaiian, and North Atlantic waters.

Taonius Borealis
''Taonius borealis'' is a glass squid belonging to the genus Taonius. It is found in the North Pacific Ocean The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the conti .... ''Taonius borealis'' is a transparent to dark purple color. They have tentacles or arms, and each arm consists of two suckers per row. The tentacular club armature consists of four hooked suckers per row, medial suckers with one or two large hooks and several small cusps. The maximum size is mantle length. Their regular habitat is mesopelagic to bathypelagic. They mostly feed on shrimps, small fishes, including myctophids, and other squids. Predators include whales, sharks, and squids.

Glass Squid
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 ...

Japetus Steenstrup
Johannes Japetus Smith Steenstrup FRS(For) HFRSE (8 March 1813 – 20 June 1897) was a Danish zoologist, biologist, and professor. Life Born in Vang, Thy on 8 March 1813, he held a lectorate in mineralogy in Sorø until 1845 when he became a professor of zoology at the University of Copenhagen. He worked on a great many subjects, including cephalopods, and also in genetics, where he discovered the principle of the alternation of generations in some parasitic worms in 1842. Steenstrup discovered (1842) the possibility of using the subfossils of the Postglacial as a means of interpreting climate changes and correlated vegetation change, which he called succession in the recent past. Two of Steenstrup's students, Christian Vaupell and Eugen Warming further developed this line of research. Japetus Steenstrup was a professor to zoologist Johan Erik Vesti Boas, who was also a student of zoologist Carl Gegenbaur, and Hans Christian Gram, inventor of the Gram stain. "Bio ...

Charles Alexandre Lesueur
Charles Alexandre Lesueur (1 January 1778 in Le Havre – 12 December 1846 in Le Havre) was a French naturalist, artist, and explorer. He was a prolific natural-history collector, gathering many type specimens in Australia, Southeast Asia, and North America, and was also responsible for describing numerous species, including the spiny softshell turtle ('' Apalone spinifera''), smooth softshell turtle ('' A. mutica''), and common map turtle ('' Graptemys geographica''). Both Mount Lesueur and Lesueur National Park in Western Australia are named in his honor. Early life Charles Alexandre Lesueur was born on January 1, 1778, to Jean-Baptiste Denis Lesueur and Charlotte Thieullent. Charlotte died when Charles was sixteen years old, and Charles' maternal grandmother took care of him and his siblings. Charles attended the Collège du Havre and possibly the Ecole publique des mathématiques et d'hydrographie. He was in military service in a cadet battalion at age fifteen and w ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Addison Emery Verrill
Addison Emery Verrill (February 9, 1839 – December 10, 1926) was an American invertebrate zoologist, museum curator and university professor. Life Verrill was born on February 9, 1839 in Greenwood, Maine, the son of George Washington Verrill and Lucy (Hillborn) Verrill. As a boy he showed an early interest in natural history, building collections of rocks and minerals, plants, shells, insects and other animals. When he moved with his family to Norway, Maine at age fourteen he attended secondary school at the Norway Liberal Institute. Verrill started college in 1859 at Harvard University and studied under Louis Agassiz. He graduated in 1862 with a B.A. He went on scientific collecting trips with Alpheus Hyatt and Nathaniel Shaler in the summer of 1860 to Trenton Point, Maine and Mount Desert Island and in the summer of 1861 to Anticosti Island and Labrador. In 1864 Verrill made reports on mining, or prospective mining, properties in New Hampshire, New York, and Pennsylvania ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clea ...

Carl Chun
Carl Chun (1 October 1852 – 11 April 1914) was a German marine biologist. Chun was born in Höchst, today a part of Frankfurt, and studied zoology at the University of Leipzig, where from 1878 to 1883 he was privat-docent of zoology and an assistant to Rudolf Leuckart. After professorial posts in Königsberg (1883–1891) and Breslau (1891–1898), he returned to Leipzig as a professor of zoology.UNI Leipzig Professorenkatalog (biographical sketch) In 1888, Chun described seasonal vertical migration (SVM) which has a periodicity of ca. 1 year.
