Halfbeak
Hemiramphidae is a family (biology), family of fishes that are commonly called halfbeaks, spipe fish or spipefish. They are a geographically widespread and numerically abundant family of epipelagic fish inhabiting warm waters around the world. The halfbeaks are named for their distinctive jaws, in which the lower jaws are significantly longer than the upper jaws. The similar viviparous halfbeaks (family Zenarchopteridae) have often been included in this family. Though not fishing, commercially important themselves, these forage fish support artisan fishing, artisanal fisheries and local markets worldwide. They are also fed upon by other commercially important predatory fishes, such as billfishes, mackerels, and sharks. Taxonomy In 1758, Carl Linnaeus was the first to scientific classification, scientifically describe a halfbeak, ''Esox brasiliensis'' (now ''Hemiramphus brasiliensis''). In 1775 Peter Forsskål described two more species as ''Esox'', ''Hemiramphus far, Esox far'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viviparous Halfbeak
Zenarchopteridae, the viviparous halfbeaks, is a family (biology), family of ray-finned fishes in the order Beloniformes. The Zenarchopteridae exhibit strong sexual dimorphism, practicing internal fertilisation, and in some cases ovoviviparous or viviparous (the family also includes oviparous species).Berra, T.M.

The members in the family are mainly found in fresh and brackish water of tropical Asia and New Guinea, but the genus ''Zenarchopterus'' also includes marine species from the Indo-Pacific. Several, such as the wrestling halfbeak, have become commonly traded fishkeeping, aquarium fish.

Hemiramphus Marginatus
''Hemiramphus'' is a genus of schooling marine fish commonly called halfbeaks, garfish, or ballyhoos, and are members of the family Hemiramphidae. They inhabit the surface of warm temperate and tropical sea, and feed on algae, plankton, and smaller fish. ''Hemiramphus'' species are edible but are more important as food fish for larger predatory species including dolphinfish and billfish. Species There are currently 11 recognized species in this genus: * '' Hemiramphus archipelagicus'' Collette & Parin, 1978 (Jumping halfbeak) * '' Hemiramphus balao'' Lesueur, 1821 (Balao halfbeak) * '' Hemiramphus bermudensis'' Collette, 1962 (Bermuda halfbeak) * '' Hemiramphus brasiliensis'' (Linnaeus, 1758) (Ballyhoo halfbeak) * '' Hemiramphus convexus'' M.

Hemiramphus Far
''Hemiramphus far'', the halfbeak, black-barred halfbeak, black-barred garfish, barred halfbeak, barred garfish or spotted halfbeak, is a schooling marine fish belonging to the Family (biology), family Hemiramphidae, the halfbeaks. It has an Indo-Pacific distribution and has invaded the eastern Mediterranean through the Suez Canal. Description ''Hemiramphus far'' has a laterally compressed body which is elongate oval in cross-section and has a very long, beak-like lower jaw with a short upper jaw which is triangular and lacks scales; there is no preorbital ridge. The total number of gill rakers on first gill arch is 25–36 with 21–27 on the second arch. It has short pectoral fins which do not extend past the nasal fossa when they are folded forwards. There are 3–9, normally 4–6, dark vertical bars on the sides and the back is bluish in colour with silvery sides. The caudal fin is asymmetrical with the lower lobe being longer than the upper lobe.

Euleptorhamphus
''Euleptorhamphus'' is a genus of halfbeaks (family Hemiramphidae) in the order Beloniformes. Species There are currently two recognized species in this genus: * '' Euleptorhamphus velox'' Poey, 1868 (Flying halfbeak) * '' Euleptorhamphus viridis'' ( van Hasselt, 1823) (Ribbon halfbeak) Both of these species are marine. ''E. velox'' occurs in coastal and oceanic waters from the western Atlantic from New England south through the Gulf of Mexico and Caribbean Sea to Recife, Brazil and eastern Atlantic from the Cape Verde Islands, Sierra Leone, and Nigeria. ''E. viridis'' is widely distributed in tropical and subtropical waters of the Indo-Pacific The Indo-Pacific is a vast biogeographic region of Earth. In a narrow sense, sometimes known as the Indo-West Pacific or Indo-Pacific Asia, it comprises the tropical waters of the Indian Ocean, the western and central Pacific Ocean, and the ....

Forage Fish
Forage fish, also called prey fish or bait fish, are small pelagic fish that feed on planktons (i.e. planktivores) and other small aquatic organisms (e.g. krill). They are in turn preyed upon by various predators including larger fish, seabirds and marine mammals, this making them keystone species in their aquatic ecosystems. The typical ocean forage fish feed at the lower trophic level of the food chain, often by filter feeding. They include particularly fishes of the order Clupeiformes (herrings, sardines, shad, hilsa, menhaden, anchovies, and sprats), but also other small fish, including halfbeaks, Atheriniformes, silversides, Smelt (fish), smelt such as capelin and goldband fusiliers. Forage fish compensate for their small size by forming shoaling and schooling, schools. Some swim in synchronised grids with their mouths open so they can efficiently filter plankton. These schools can become immense Shoaling and schooling, shoals which move along coastlines and Fish migration, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemiramphus Brasiliensis
The ballyhoo halfbeak, ballyhoo, balahu, redtailed balao or yellowtail ballyhoo (''Hemiramphus brasiliensis'') is a baitfish of the halfbeak family (Hemiramphidae). It is similar to the Balao halfbeak (''H. balao'') in most features. Some are used for trolling by saltwater anglers.McBride, Richard S., Lisa Foushee, and Behzad Mahmoudi. 1996.

Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Günther
Albert Karl Ludwig Gotthilf Günther , also Albert Charles Lewis Gotthilf Günther (3October 18301February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described. Early life and career Günther was born in Esslingen in Swabia ( Württemberg). His father was a ''Stiftungs-Commissar'' in Esslingen and his mother was Eleonora Nagel. He initially schooled at the Stuttgart Gymnasium. His family wished him to train for the ministry of the Lutheran Church for which he moved to the University of Tübingen. A brother shifted from theology to medicine, and he, too, turned to science and medicine at Tübingen in 1852. His first work was "''Ueber den Puppenzustand eines Distoma''" (On the pupal state of ''Distoma''). He graduated in medicine with an M.D. from Tübingen in 1858, the same year in which he published a handbook ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Type
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the scientific name of every taxon is al ...
