''Scatophagus'' is a genus of ray-finned fishes belonging to the Family (biology), family Scatophagidae. They are found in the Indo-Pacific region. Species in this genus are referred as ''spotted scats''. Taxonomy ''Scatophagus'' was first formally described as a genus in 1831 by the French zoologist Georges Cuvier with ''Chaetodon argus'' which had been Species description, described from India by Linnaeus in 1766 later designated as the type species.

Scatophagus Argus
''Scatophagus argus'', the spotted scat, butterfish, mia mia, spotted butterfish or tiger scat, is a species of fish in the scat family (biology), family Scatophagidae. It occurs in two basic color morph (zoology), morphs which are called green scat and ruby or red scat. This fish is generally distributed around the Indo-Pacific region, to Japan, New Guinea, and southeastern Australia.

Scatophagus Tetracanthus
''Scatophagus tetracanthus'', the scatty or African scat is a species of ray-finned fish belonging to the family Scatophagidae, the scats. It is found in eastern Africa and Madagascar and in New Guinea and northern Australia. Taxonomy ''Scatophagus tetracanthus'' was first formally described ''Chaetodon tetracanthus'' as in 1802 by the French naturalist Bernard Germain de Lacépède with no type locality given, Lacépède's description was based on a drawing and manuscript by Philibert Commerson. The specific name is a compound of ''tetra'' meaning "four" and ''acanthus'' which means "spines", a reference to the four anal fin spines.

The soft rayed parts of the dorsal and anal fins are triangular and nearly join with the truncate caudal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scatophagidae
Scatophagidae, the scats are a small family of ray-finned fishes in the order Perciformes. They are found in the Indo-Pacific region but one species has been introduced elsewhere. Taxonomy Scatophagidae was first formally described as a family in 1883 by the American ichthyologist Theodore Nicholas Gill. They are classified in the superfamily Siganiodea, along with the rabbitfishes of the family Siganidae, within the suborder Percoidei in the 5th edition of '' Fishes of the World''. Other workers have classified them with the surgeonfishes in the order Acanthuriformes or as ''incertae sedis'' within the series Eupercaria. The name of the family comes from its type genus ''Scatophagus'' and this is a compound of ''skatos'' meaning "dung" and ''phaga'' which means to eat, a reference to this species purported taste for human faeces. Genera There are two genera classified within the Scatophagidae, each containing two extant species: * '' Scatophagus'' Cuvier, 1831 * '' Sel ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In ...

Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "'' Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 17696 May 1859) was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and scie ...

Gill Net
Gillnetting is a fishing method that uses gillnets: vertical panels of netting that hang from a line with regularly spaced floaters that hold the line on the surface of the water. The floats are sometimes called "corks" and the line with corks is generally referred to as a "cork line." The line along the bottom of the panels is generally weighted. Traditionally this line has been weighted with lead and may be referred to as "lead line." A gillnet is normally set in a straight line. Gillnets can be characterized by mesh size, as well as colour and type of filament from which they are made. Fish may be caught by gillnets in three ways: # Wedged – held by the mesh around the body. # Gilled – held by mesh slipping behind the opercula. # Tangled – held by teeth, spines, maxillaries, or other protrusions without the body penetrating the mesh. Most often fish are gilled. A fish swims into a net and passes only part way through the mesh. When it struggles to free ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Florida
Florida is a state located in the Southeastern region of the United States. Florida is bordered to the west by the Gulf of Mexico, to the northwest by Alabama, to the north by Georgia, to the east by the Bahamas and Atlantic Ocean, and to the south by the Straits of Florida and Cuba; it is the only state that borders both the Gulf of Mexico and the Atlantic Ocean. Spanning , Florida ranks 22nd in area among the 50 states, and with a population of over 21 million, it is the third-most populous. The state capital is Tallahassee, and the most populous city is Jacksonville. The Miami metropolitan area, with a population of almost 6.2 million, is the most populous urban area in Florida and the ninth-most populous in the United States; other urban conurbations with over one million people are Tampa Bay, Orlando, and Jacksonville. Various Native American groups have inhabited Florida for at least 14,000 years. In 1513, Spanish explorer Juan Ponce de León became the first k ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Society Islands
The Society Islands (french: Îles de la Société, officially ''Archipel de la Société;'' ty, Tōtaiete mā) are an archipelago located in the South Pacific Ocean. Politically, they are part of French Polynesia, an overseas country of the French Republic. Geographically, they form part of Polynesia. The archipelago is believed to have been named by Captain James Cook during his first voyage in 1769, supposedly in honour of the Royal Society, the sponsor of the first British scientific survey of the islands; however, Cook wrote in his journal that he called the islands ''Society'' "as they lay contiguous to one another." History Dating colonization The first Polynesians are understood to have arrived on these islands around 1000AD. Oral history origin The islanders explain their origins in term of a orally transmitted story. The feathered god Ta'aroa lay in his shell. He called out but no-one answered, so he went back into his shell, where he stayed for aeons. When h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Total 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 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. Simply put, 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 fish characte ...

Ctenoid
A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages. The term ''scale'' derives from the Old French , meaning a shell pod or husk. Scales vary enormously in size, shape, structure, and extent, ranging from strong and rigid armour plates in fishes such as shrimpfishes and boxfishes, to microscopic or absent in fishes such as eels and anglerfishes. The morphology of a scale can be used to identify the species of fish it came from. Scales originated within the jawless ostracoderms, ancestors to all jawed fishes today. Most bony fishes are covered with the cycloid scales of salmon and carp, or the ctenoid scales of perch, or the ganoid scales of sturgeons and gars. Cartilaginous fishes (sharks and rays) are covered with placoid scales. Some species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
