Argyropelecus
''Argyropelecus'' is an oceanic ray-finned fish genus in the deep sea hatchetfish family Sternoptychidae. A collective name is " silver hatchetfishes", but this can also refer to a species of the freshwater hatchetfishes which are not particularly closely related to this. The large pupils of these marine hatchetfishes enable them to see dim objects in the deep sea, where light barely penetrates. Species There are currently seven recognized extant species in this genus: * ''Argyropelecus aculeatus'' Valenciennes, 1850 (lovely hatchetfish, Atlantic silver hatchetfish) * '' Argyropelecus affinis'' Garman, 1899 (Pacific hatchetfish) * '' Argyropelecus gigas'' Norman, 1930 (giant hatchetfish, greater silver hatchetfish) * ''Argyropelecus hemigymnus'' Cocco, 1829 (half-naked hatchetfish, short silver hatchetfish, spurred hatchetfish) * '' Argyropelecus lychnus'' Garman, 1899 (tropical hatchetfish) * '' Argyropelecus olfersii'' (G.

Argyropelecus Olfersii
''Argyropelecus olfersii'' is a common species of marine hatchetfish, found in mesopelagic waters. Discovery and naming ''Argyropelecus olfersii'' was described by Georges Cuvier in Chapter 27 of '' Histoire Naturelle des Poissons'', based on specimens held in the National Museum of Natural History in Paris and the Natural History Museum, Berlin. The specific name honours the German diplomat and natural historian Ignaz von Olfers, who presented the Berlin specimen to the museum upon his return from a diplomatic excursion to Brazil. Distribution and habitat ''A. olfersii'' is found in temperate waters worldwide, with a preferred temperature range of 5.1-13.3°C. The fish is present in all oceans save the Southern, however records are rare from the Indian Ocean. During daylight hours, subadult and adult fish live at depths of 200-800m, undergoing a vertical migration to 100-600m at sunset.

Argyropelecus Affinis
''Argyropelecus affinis'' is a species of ray-finned fish in the family Sternoptychidae, found in the tropical and subtropical Atlantic, Indian and Pacific Oceans. Common names for this fish include Pacific hatchetfish, deepsea hatchetfish and slender hatchetfish. It inhabits the mesopelagic zone and is either non-migratory or performs short daily vertical migrations. Description ''Argyropelecus affinis'' is a small laterally compressed fish with a standard length of up to . It has a vertical mouth and tubular eyes that are directed upwards. There is a short spine in front of the operculum but no spine behind the eye. The dorsal fin has 9 short soft rays and there is also a dorsal adipose fin. The pectoral fin has 11 or 12 soft rays, the pelvic fin 6 and the anal fin 13. There are several short post-abdominal spines. The swim bladder is gas-filled and well-developed. This fish has a dark-coloured back and silvery sides, with darker pigment along the lateral line. The scales ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argyropelecus Hemigymnus
''Argyropelecus hemigymnus'', the half-naked hatchetfish, short silver hatchetfish or spurred hatchetfish, is a deep-sea hatchetfish of the genus ''Argyropelecus'' found mesopelagically in the Atlantic, Indian, and Pacific Oceans as well as in the Mediterranean Sea. It is a small species rarely exceeding standard length. It feeds on zooplankton, particularly ostracods and copepods. Sexual maturation occurs at length of about 22 mm, and adult males have more developed olfactory organs than females, i.e. the species is Sexual dimorphism, sexually dimorphic.

Argyropelecus Sladeni
''Argyropelecus sladeni'', or Sladen's hatchetfish, is a species of ray-finned fish in the family Sternoptychidae, found in the tropical and subtropical Atlantic, Indian and Pacific Oceans. This small fish lives in the mesopelagic zone by day and makes a daily vertical migration to the epipelagic zone at night. Etymology The fish is named in honor of British echinoderm biologist Percy Sladen (1849-1900) and the Percy Sladen Memorial Trust, which funded the Indian Ocean expedition that collected the type species. Description ''Argyropelecus sladeni'' is a small, deep-bodied hachetfish with an abdominal keel and a maximum standard length of about . The mouth is of medium size, the tubular eyes point upwards, the dorsal fin has nine soft rays and is three times as long as it is high, and the adipose dorsal fin has a long base. The pectoral fins have 10 to 11 soft rays, the pelvic fins have 6 and the anal fin is in two parts, with seven soft rays in the front part and five behind. ...

It is found in every ocean except the north Pacific in the mesopelagic zone of tropical and subtropical waters. "Giant" in relative terms only, this is the largest species of marine hatchetfishes, often exceeding standard length Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish m ....

Argyropelecus Aculeatus
''Argyropelecus aculeatus'', the lovely hatchetfish or Atlantic silver hatchetfish, is a species of fish in the family Sternoptychidae. It may exceed standard length (SL). It lives in the mesopelagic zone of all oceans and performs diel vertical migration. ''A. aculeatus'' feeds on a large range of prey items; in the Gulf of Mexico ostracods and copepods dominated the diet of small individuals (<30 mm SL) and euphausiid

Deep Sea 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.

Sternoptychidae
The marine hatchetfishes or deep-sea hatchetfishes as well as the related bottlelights, pearlsides and constellationfishes are small deep-sea ray-finned fish of the stomiiform family Sternoptychidae.

Anastasio Cocco
Anastasio Cocco (29 August 1799, Messina – 26 February 1854, Messina) was an Italians, Italian naturalist who specialized in marine biology. Cocco was a pharmacist. He was especially interested in Ichthyology, 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 and August David Krohn. Works Partial list * Cocco, A. 1829.

Charles Tate Regan
Charles Tate Regan FRS (1 February 1878 – 12 January 1943) was a British ichthyologist, working mainly around the beginning of the 20th century. He did extensive work on fish classification schemes. Born in Sherborne, Dorset, he was educated at Derby School and Queens' College, Cambridge and in 1901 joined the staff of the Natural History Museum, where he became Keeper of Zoology, and later director of the entire museum, in which role he served from 1927 to 1938. Regan was elected Fellow of the Royal Society in 1917. Regan mentored a number of scientists, among them Ethelwynn Trewavas, who continued his work at the British Natural History Museum. Species Among the species he described is the Siamese fighting fish (''Betta splendens''). In turn, a number of fish species have been named ''regani'' in his honour: *A Thorny Catfish '' Anadoras regani'' (Steindachner, 1908) *The Dwarf Cichlid '' Apistogramma regani'' *'' Apogon regani'' *A Catfish '' Astroblepus regani'' * ...
