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] |
Stomiiform
Stomiiformes is an order of deep-sea ray-finned fishes of very diverse morphology. It includes, for example, dragonfishes, lightfishes ( Gonostomatidae and Phosichthyidae), loosejaws, marine hatchetfishes and viperfishes. The order contains 4 families (5 according to some authors) with more than 50 genera and at least 410 species. As usual for deep-sea fishes, there are few common names for species of the order, but the Stomiiformes as a whole are often called dragonfishes and allies or simply stomiiforms. The scientific name means "''Stomias''-shaped", from '' Stomias'' (the type genus) + the standard fish order suffix "-formes". It ultimately derives from Ancient Greek ''stóma'' (στόμᾶ, "mouth") + Latin ''forma'' ("external form"), the former in reference to the huge mouth opening of these fishes. Description and ecology Members of this order are mostly pelagic fishes living in deep oceanic waters. Their distribution around the world's oceans is very wide, ran ...

Phosichthys
''Phosichthys argenteus'', the silver lightfish, a species of lightfish and the only member of the genus ''Phosichthys'', is found in deep subtropical waters of all oceans, from depths of 500 to 2,000 m.

Photophore
A photophore is a glandular organ that appears as luminous spots on various marine animals, including fish and cephalopods. The organ can be simple, or as complex as the human eye; equipped with lenses, shutters, color filters and reflectors, however unlike an eye it is optimized to produce light, not absorb it. The bioluminescence can variously be produced from compounds during the digestion of prey, from specialized mitochondrial cells in the organism called photocytes ("light producing" cells), or, similarly, associated with symbiotic bacteria in the organism that are cultured. The character of photophores is important in the identification of deep sea fishes. Photophores on fish are used for attracting food or for camouflage from predators by counter-illumination. Photophores are found on some cephalopods including the firefly squid, which can create impressive light displays, as well as numerous other deep sea organisms such as the pocket shark Mollisquama mississipp ...

Krill
Krill are small crustaceans of the order Euphausiacea, and are found in all the world's oceans. The name "krill" comes from the Norwegian word ', meaning "small fry of fish", which is also often attributed to species of fish. Krill are considered an important trophic level connection – near the bottom of the food chain. They feed on phytoplankton and (to a lesser extent) zooplankton, yet also are the main source of food for many larger animals. In the Southern Ocean, one species, the Antarctic krill, ''Euphausia superba'', makes up an estimated biomass of around 379,000,000 tonnes, making it among the species with the largest total biomass. Over half of this biomass is eaten by whales, seals, penguins, seabirds, squid, and fish each year. Most krill species display large daily vertical migrations, thus providing food for predators near the surface at night and in deeper waters during the day. Krill are fished commercially in the Southern Ocean and in the waters around Japa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
