Vinciguerria Lucetia
''Vinciguerria lucetia'' is a species of marine ray-finned fish in the genus ''Vinciguerria'' known by the common name Panama lightfish. It is a small bioluminescent fish, with two rows of tiny photophores along its body. It is very abundant in the tropical Indo-Pacific where it makes large vertical migrations each day. Description ''Vinciguerria lucetia'' is a small fish growing to a maximum length of about . It is an elongated, laterally compressed species with a disproportionately large head which is compressed and conical, with a wide mouth and pointed snout. There are photophores on the head and two lateral rows of pearl-like photophores on the underside of the body. The dorsal fin is short and consists of thirteen to fourteen soft rays. The origin of the anal fin, which consists of fourteen to fifteen soft rays, is below the rear of the dorsal fin. The pectoral fins are set low on the body and the caudal fin is deeply forked. The dorsal surface of this fish is blackish, wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vinciguerria Attenuata
''Vinciguerria attenuata'', commonly known as the slender lightfish, is a small species of ray-finned fish in the family Phosichthyidae, found in deep water in warmer parts of the Atlantic, the Indian and Pacific Oceans. Description ''Vinciguerria attenuata'' is a moderately elongate fish with a tapering body growing to a length of about . The eyes are slightly tubular and set close together, giving vision both upwards and sideways. The mouth is large, with a single row of teeth, some long and some short. The dorsal fin has 13 to 15 soft rays and is set in front of a small adipose fin (a small fleshy fin without supporting rays). The pectoral fins have 9 to 10 soft rays, the pelvic fins 6 to 7 and the anal fin 13 to 16. There are photophores (light-producing organs) on the lower half of the head and in rows on the underside of the fish. The dorsal surface of the body is dark, the flanks are silvery and the fins are colourless, without streaks. Distribution and habitat ''V. atten ...

Vinciguerria Poweriae
''Vinciguerria poweriae'' (also known as Power's deep-water bristle-mouth fish) is a species of lightfish belonging to the genus ''Vinciguerria''. They are mostly found in seawater deep during the day and deep at night. They feed on small crustaceans. Etymology The fish is named in honor of Cocco’s friend and colleague Jeanne Villepreux-Power (1794-1871), also known as Jeanette Power, a marine biologist who was famous for her work on the octopus ''Argonauta argo''. She was able to demonstrate that the octopus produced its own shell, rather than as was thought, acquiring it from a different organism similar to the way a hermit crab does. She also was the first person to create an aquaria for the experimentation of aquatic organisms. Description ''Vinciguerria poweriae'' is a moderately slender and elongate fish growing to a length of about . The eyes are widely spaced and are not tubular, and the mouth is large, with a single row of teeth of varying length. The dorsal fin h ...

Vinciguerria Nimbaria
The oceanic lightfish, ''Vinciguerria nimbaria'', a lightfish of the genus ''Vinciguerria ''Vinciguerria'' is a genus of lightfishes, family Phosichthyidae. It is named for Dr. Decio Vinciguerra (1856–1934), an Italian ichthyologist. Included species There are currently five extant species recognized in this genus: * '' Vinciguerri ...'', is found in all deep tropical and subtropical oceans and seas, from depths of 20 to 5,000 m. Its length is between 2 and 5 cm. It is the main prey of tuna during the tuna fishing season (late autumn and winter) in the equatorial Atlantic. Its own diet is varied and is dependent on its location. In equatorial locations it has been found to behave as a mesopelagic fish and as an opportunistic mesozooplankton feeder, whilst further north in oligotrophic typical tropical structures it was found to behave as an epipelagic fish, feeding on the dominant small prey during the daytime.

Decio Vinciguerra
Decio Vinciguerra (23 May 1856 – 5 October 1934) was an Italian physician and ichthyologist who for many years was Director of the Aquarium of Rome. Early years Decio Vinciguerra was born in Genoa on 23 May 1856. He studied at the University of Genoa, and in 1878 obtained a degree in Medicine and Surgery. Immediately after graduating he was appointed assistant to the Chair of Zoology and Comparative Anatomy in the University of Genoa. He was naturally attracted to zoology, which he studied further, obtaining a doctorate degree. He became a botanist and a zoologist with particular interest in ichthyology. Vinciguerra was a member of the Italian expedition to Tierra del Fuego in 1882 led by Giacomo Bove. Although officially both zoologist and botanist, in fact Carlos Luigi Spegazzini from Buenos Aires handled the botanical work. The geologist Domenico Lovisato and the hydrologist Giovanni Roncagli made up the scientific party. Vinciguerra made valuable collections and observatio ...

Phosichthyidae
Lightfishes are small stomiiform fishes in the family Phosichthyidae The earliest fossils of lightfishes are from Oligocene-aged Paratethyan marine strata in the Czech Republic. They are very small fishes found in oceans throughout the world: most species grow no longer than 10 cm, while those in the genus ''Vinciguerria'' only reach 4 cm or so. They make up for their small size with abundant numbers: ''Vinciguerria'' is thought — with the possible exception of ''Cyclothone'' — to be the most abundant genus of vertebrates. Deep-sea trawls of the Humboldt Current in the southeast Pacific have found that lightfishes make up 85% by mass of mesopelagic fishes, with ''Vinciguerria lucetia'' by far the most numerous species. They are bioluminescent Bioluminescence is the production and emission of light by living organisms. It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some Fungus, fun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anastasio Cocco
Anastasio Cocco (29 August 1799, Messina – 26 February 1854, Messina) was an Italian naturalist who specialized in marine biology. Cocco was a pharmacist. He was especially interested in fish and described several taxa from the Straits of Messina. In 1852 his friend the German scientist Eduard Rüppell named a fish ''Microichthys coccoi'' to honor his name. He was a friend and correspondent of many other naturalists notably Charles Lucien Bonaparte, Antoine Risso Giuseppe Antonio Risso (8 April 1777 – 25 August 1845), called Antoine Risso, was a Niçard and naturalist. Risso was born in the city of Nice in the Duchy of Savoy, and studied under Giovanni Battista Balbis. He published ' (1810), ' (182 ... and August David Krohn. Works Partial list * Cocco, A. 1829.

Species
In biology, a species is the basic unit of Taxonomy (biology), 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 reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), 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 binomial nomenclature, 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 specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', " dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
