Lobotidae
Lobotidae is a family of ray-finned fishes that includes the tripletails, which are circumtropical marine fishes, and tiger perches, which are Asian freshwater fishes. The family is placed in the order Spariformes in the 5th edition of ''Fishes of the World'' but this classification and the taxa included within the family is not agreed on by all workers. Taxonomy Lobotidae was first proposed as a family in 1861 by the American biologist Theodore Gill. The 5th edition of Fishes of the World classifies the Lobotidae within the order Spariformes and provisionally includes the genus '' Datnioides'' in the family. Other workers have included a third genus, '' Hapalogenys'' in the Lobotidae. However, yet more workers place these three taxa in monotypic families within the order Lobotiformes in the series Eupercaria. Genera Lobotidae contaons the following genera: * ''Lobotes'' Cuvier, 1830 (Triplefins) * '' Datnioides'' Bleeker, 1853 (Tiger perches) Characteristics Lobotidae have too ...

Datnioides
''Datnioides'' is a genus of ray-finned fish belonging to the family Lobotidae. These fishes are commonly known as tigerfish, tiger perch or freshwater tripletails. These fishes are found in the rivers of southern Asia and new Guinea. Taxonomy ''Datnioides'' was first proposed as a genus in 1853 by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker, in 1876 Bleeker designated ''Datnoides polota'', which was the same as ''Coius polota'' that Francis Hamilton had described in 1822 from the Ganges, as its type species. In 2000 Maurice Kottelat determined that the type species of the genus ''Coius'', ''Coius cobojius'', was a junior synonym of ''Anabas testudineus'' so ''Coius'' is a junior synonym of '' Anabas'', with ''Datnioides'' being the correct name for the tiger perch genus. Historically this genus was classified in the monotypic family Datnioididae but the 5th edition of the ''Fishes of the World'' classifies this genus as one of two genera in the family ...

Lobotes
''Lobotes'' is a genus of ray-finned fishes belonging to the family Lobotidae known as the tripletails. These fishes are found in subtropical and tropical waters in all oceans. Taxonomy ''Lobotes'' was first proposed as a genus in 1830 by the French zoologist Georges Cuvier with ''Holocentrus surinamensis'', originally described by Marcus Elieser Bloch in 1790 from Suriname, as its type species. Some authorities treat ''Lobotes'' as a monospecific genus with ''L. pacifica'' being regarded as a synonym of a single pantropical ''L. surinamensis''. ''Lobotes'' is one of two genera in the family Lobotidae which the 5th edition of ''Fishes of the World'' classifies in the order Spariformes. Species The currently recognized species in this genus are: * '' Lobotes pacifica'' C. H. Gilbert, 1898 (Pacific tripletail) * '' Lobotes surinamensis'' (Bloch, 1790) (Atlantic tripletail) Characteristics ''Lobotes'' species are characterised by having a rather compressed rectangular body with a ...

Atlantic Tripletail
The Atlantic tripletail (''Lobotes surinamensis''), also known as the black grunt, black perch, buoy fish, buoyfish, brown triple tail, brown tripletail, conchy leaf, dusky triple-tail, dusky tripletail, flasher, sleepfish, triple tail, triple-tail, tripletail, or tripple tail is a species of marine ray-finned fish belonging to the Family (biology), family Lobotidae. This fish is found in tropical and subtropical waters around the world except for the Eastern Pacific Ocean, where its Sister group, sister species, the Lobotes pacifica, Pacific tripletail (''Lobotes pacifica'') is found. Taxonomy The Atlantic tripletail was first formally Species description, described in 1790 as ''Holocentrus surinamensis'' by the German physician and naturalist Marcus Elieser Bloch with its Type locality (biology), type locality given as the Caribbean Sea off Suriname. In 1830 Georges Cuvier proposed the new genus ''Lobotes'' with ''Holocentrus surinamensis'' its type species by Monotypic tax ...

Spariformes
Spariformes is an order of ray-finned fishes consisting of six families within the series Percomorpha. Taxonomy Spariformes was first used as a taxonomic term in 1860 by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker. Traditionally the taxa within the Spariformes were classified within the Perciformes, with some authorities using the term "Sparoid lineage" for the families Centracanthidae, Nemipteridae, Lethrinidae and Sparidae. Since then the use of molecular phylogenetics in more modern classifications has meant that the Spariformes is recognised as a valid order within the Percomorpha containing six families, with Callanthidae, Sillaginidae and Lobotidae included. Other workers have found that the Centracanthidae is synonymous with Sparidae and that the Spariformes contains only the remaining three families of the "Sparoid lineage". Studies have further suggested that the order Tetraodontiformes are the closest taxonomic grouping to the Spariformes. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Datnioides Campbelli
''Datnioides campbelli'', the New Guinea tiger perch, New Guinea tigerfish or Campbell's tigerfish, is a species of ray-finned fish belonging to the family Lobotidae. This species is found in both fresh and brackish waters in rivers, swamps and tidal creeks in southern New Guinea. Taxonomy ''Datnioides campbelli'' was first formally described in 1939 by the Australian ichthyologist Gilbert Percy Whitley with its type locality given as the Fly River in Papua New Guinea. The 5th edition of the ''Fishes of the World'' classifies its genus as one of two in the family Lobotidae, alongside the tripletails in the genus ''Lobotes'', within the order Spariformes. Etymology ''Datnioides campbelli'' has a specific name that honours the RAAF officer Flight Lieutenant Stuart Campbell who collected the type. Description ''Datnioides campbelli'' has the characteristic toothless palatine and vomer of ''Datnioides'' tiger perches with a rounded caudal fin and rounded lobes on the anal and se ...

Hapalogenys
''Hapalogenys'', the barbeled grunters or velveltchins, is a genus of marine ray-finned fish, it is the only genus in the monotypic family Hapalogenyidae, also spelled Hapalogeniidae. The species of this genus are found in depths between in coastal areas and river mouths from the shores of southern Japan to the Bay of Bengal and Northwestern Australia. Etymology ''Hapalogenys'' is a compound of ''hapalos'' meaning "soft" and ''genys'' meaning "chin", Richardson stating that this referred to "velvety softness of the chin and lower lip, which is made more conspicuous by contrast with the rigidly rough scales that cover the rest of the head". Characteristics ''Hapalogenys species have compressed bodies. They have 10 pores on and to the rear of the chin, these include a pair of tiny pores near the symphysis, The lower jaw and chin have dense clusters of short barbels. They have small teeth which are arranged in bands on the jaws, vomer, and palatines. They have 7 branchiostegal ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eupercaria
Percomorpha () is an extremely large and diverse clade of ray-finned fish. With more than 17,000 known species (including tuna, seahorses, gobies, cichlids, flatfish, wrasse, perches, anglerfish, and pufferfish) known from both marine and freshwater ecosystems, it is the most speciose clade of extant vertebrates. Evolution Percomorpha are the most diverse group of teleost fish today. Teleosts, and percomorphs in particular, thrived during the Cenozoic era. Fossil evidence shows that there was a major increase in size and abundance of teleosts immediately after the mass extinction event at the Cretaceous-Paleogene boundary ago. The oldest known percomorph fossils are of the early tetraodontiforms '' Protriacanthus'' and Cretatriacanthidae from the Santonian to Campanian of Italy and Slovenia. A higher diversity of early percomorphs is also known from the Campanian of Nardò, Italy, and these also show some level of diversification into modern orders, with representatives ...

Palatine Bone
In anatomy, the palatine bones (; derived from the Latin ''palatum'') are two irregular bones of the facial skeleton in many animal species, located above the uvula in the throat. Together with the maxilla, they comprise the hard palate. Structure The palatine bones are situated at the back of the nasal cavity between the maxilla and the pterygoid process of the sphenoid bone. They contribute to the walls of three cavities: the floor and lateral walls of the nasal cavity, the roof of the mouth, and the floor of the orbits. They help to form the pterygopalatine and pterygoid fossae, and the inferior orbital fissures. Each palatine bone somewhat resembles the letter L, and consists of a horizontal plate, a perpendicular plate, and three projecting processes—the pyramidal process, which is directed backward and lateral from the junction of the two parts, and the orbital and sphenoidal processes, which surmount the vertical part, and are separated by a deep notch, the s ...

Total Length
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery biology. Overall length Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. This measurement excludes the length of the caudal (tail) fin. Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes ( lampreys) and usually Elasmobranchii (shark Sharks are a group of elasmobranch cartilaginous fish characterized by a ...

Anal Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish ( Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish ( Chondrichthyes) and jawless fish ( Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
