Stomiiformes
Stomiiformes is an order (biology), order of deep-sea ray-finned fishes of very diverse Morphology (biology), morphology. It includes, for example, Barbeled dragonfish, dragonfishes, lightfishes (Gonostomatidae and Phosichthyidae), loosejaws, marine hatchetfishes and viperfishes. The order contains 4 family (biology), families (5 according to some authors) with more than 50 genus, 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. The earliest stomiiform is ''Paravinciguerria'' from the Cenomanian of Morocco and Italy. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbeled Dragonfish
Stomiidae is a family (biology), family of deep-sea ray-finned fish, including the barbeled dragonfishes, that live in all oceans in a wide range of depths. They are quite small, usually around 15 cm, up to 26 cm, and they exhibit a strong sexual dimorphism. These fish are apex predators and have enormous jaws filled with fang-like teeth. They are also able to hinge the neurocranium and upper-jaw system, which leads to the opening of the jaw to more than 100 degrees. This ability allows them to consume extremely large prey, often 50% greater than their standard length. Evolution Due to their extreme habitats, stomiids are very rare in the fossil record. The oldest known genus is ''Azemiolestes'' Prokofiev, 2001 from the Middle Eocene (Lutetian) of Georgia (country), Georgia. Other fossil genera include ''Abruzzoichthys'' Carnevale, 2002 from the Middle Miocene of Italy and ''Mrazecia'' Pauca, 1929 from the Early Oligocene of Romania. Genera File:Astronesthes niger. ...

Phosichthyidae
Lightfishes are small stomiiform fishes in the family Phosichthyidae The earliest fossils of lightfishes are of the genus †'' Sytchevskia'' Prokofiev, 2002, known from Middle Eocene-aged Tethyan marine strata in Georgia. 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 fishes, possessing rows of photophores along their sides, with which they hunt planktonic invertebrates, especially krill, copepod Copepods (; meaning 'oar-feet') are ...

Gonostomatidae
The Gonostomatidae are a family of Mesopelagic zone, mesopelagic marine fish, commonly named bristlemouths, lightfishes, or anglemouths. It is a relatively small family (biology), family, containing only eight known genus, genera and 32 species. However, bristlemouths make up for their lack of diversity with relative abundance, numbering in the hundreds of trillion (short scale), trillions to quadrillions. The genus ''Cyclothone'' (with 13 species) is thought to be one of the most abundant vertebrate genera in the world. The fossil record of this family dates back to the Miocene epoch (geology), epoch. Living bristlemouths were discovered by William Beebe in the early 1930s and described by Lev Berg, L. S. Berg in 1958. The fish are mostly found in the Atlantic, Indian Ocean, Indian, and Pacific Oceans, although the species ''Cyclothone microdon'' may be found in Arctic waters. They have elongated bodies from in length. They have a number of green or red light-producing photoph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viperfish
A viperfish is any species of marine fish in the genus ''Chauliodus''. Viperfish are mostly found in the mesopelagic zone and are characterized by long, needle-like teeth and hinged lower jaws. A typical viperfish grows to lengths of . Viperfishes undergo diel vertical migration and are found all around the world in tropical and temperate oceans. Viperfishes are capable of bioluminescence and possess photophores along the ventral side of their body, likely used to camouflage them by blending in with the less than 1% of light that reaches to below 200 meters depth. Habitat Viperfish live in meso- and bathypelagic environments and have been found dominating submarine calderas such as the Kurose Hole, which is the site with the highest ''Chauliodus'' density known in the world. Viperfish also engage in diel vertical migration, meaning they migrate up into more productive waters during the night to feed. However, it is likely that only part of the total population of viperfish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Hatchetfish
Marine hatchetfishes or deep-sea hatchetfishes are small deep-sea mesopelagic ray-finned fish of the stomiiform subfamily Sternoptychinae. They should not be confused with the freshwater hatchetfishes, which are not particularly closely related Teleostei in the characiform family Gasteropelecidae. (2006): ''Fishes of the World'' (4th ed.). John Wiley & Sons, Inc. p.209 The scientific name means "''Sternoptyx''-subfamily", from '' Sternoptyx'' (the type genus) + the standard animal family suffix "-inae". It ultimately derives from Ancient Greek ''stérnon'' (στέρνον, "breast") + ''ptýx'' (πτύξ, "a fold/crease") + Latin ''forma'' ("external form"), the Greek part in reference to the thorax shape of marine hatchetfishes. Description and ecology Found in tropical, subtropical and temperate waters of the Atlantic, Pacific and Indian Oceans, marine hatchetfishes range in size from '' Polyipnus danae'' at to the c.-long giant hatchetfish (''Argyropelecus gigas'').

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Ancient Greek
Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Name
In Taxonomy (biology), taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammar, Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the ''generic name (biology), generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
