Gasterosteiformes
Gasterosteoidei is a suborder of ray-finned fishes that includes the sticklebacks and relatives, the 5th edition of ''Fishes of the World'' classifies this suborder within the order Scorpaeniformes. Systematics Gasterosteoidei is treated as a suborder within the order Scorpaeniformes in the 5th edition of ''Fishes of the World'', but in other phylogenetic classifications it is treated as the infraorder Gasterosteales within the suborder Cottoidei or as a sister clade to the Zoarcales in the order Zoarciformes. Indostomidae is included within Gasterosteoidei in ''Fishes of the World but according to Betancur ''et al'' its inclusion in the clade renders it paraphyletic and they classify that family within the monotypic suborder Indostomoidei within the Synbranchiformes. Historically, Gasterosteoidei was treated as a suborder within the order Gasterostiformes and often included the sea horses, pipefishes and their relatives as suborder Syngnathoidei, with the sticklebacks and rel ...

Syngnathiformes
The Syngnathiformes are an order of ray-finned fishes that includes the trumpetfishes and seahorses.FishBase (2005)Order Summary for Syngnathiformes Version of 2005-FEB-15. Retrieved 19 Aug 2008. These fishes have elongated, narrow, bodies surrounded by a series of bony rings, and small, tubular mouths. The shape of their mouth—in at least syngnathids—allows for the ingestion of prey at close range via suction. Several groups of Syngnathiformes live among seaweed and swim with their bodies aligned vertically, to blend in with the stems. The most defining characteristic of this order is their reverse sexual system. In this order, males conduct in specialized brooding and rearing of the embryos. The males house eggs in an osmoregulated pouch or adhere eggs to their tail until the eggs reach maturity. The name Syngnathiformes means "conjoined-jaws". It is derived from Ancient Greek ''syn'' (συν, "together") + ''gnathos'' (γνάθος, "jaw"). The ending for fish orders "- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Perciformes
Perciformes (), also called the Percomorpha or Acanthopteri, is an order or superorder of ray-finned fish. If considered a single order, they are the most numerous order of vertebrates, containing about 41% of all bony fish. Perciformes means "perch-like". Perciformes is an Order within the Clade Percomorpha consisting of "perch-like" Percomorphans. This group comprises over 10,000 species found in almost all aquatic ecosystems. The order contains about 160 families, which is the most of any order within the vertebrates. It is also the most variably sized order of vertebrates, ranging from the ''Schindleria brevipinguis'' to the marlin in the genus ''Makaira''. They first appeared and diversified in the Late Cretaceous. Among the well-known members of this group are perch and darters (Percidae), sea bass and groupers (Serranidae). Characteristics The dorsal and anal fins are divided into anterior spiny and posterior soft-rayed portions, which may be partially or compl ...

Synbranchiformes
Synbranchiformes, often called swamp eels, is an order of ray-finned fishes that are eel-like but have spiny rays, indicating that they belong to the superorder Acanthopterygii. Taxonomy No synbrachiform fossil is known. The Mastacembeloidei were removed from the Perciformes and added to the Synbranchiformes after a phylogenetic analysis by Johnson and Patterson. These authors consider the Synbranchiformes to be part of a monophyletic group called Smegmamorpha, also containing Mugilimorpha, Atherinomorpha, Gasterosteiformes, and Elassomatidae. Later authors have proposed that the Synbranchiformes along with the Anabantiformes, Carangiformes, Istiophoriformes and Pleuronectiformes form a sister clade to the Ovalentaria which has been called the “Carangimorpharia” but in the 5th Edition of Fishes of the World this clade remained unnamed and unranked. There are a total of about 99 species divided over 15 genera in three families. There are two suborders: Synbranchoidei and Mast ...

Dactylopteridae
The flying gurnards are a family, Dactylopteridae, of marine fish notable for their greatly enlarged pectoral fins. As they cannot literally fly or glide in the air (like flying fish), an alternative name preferred by some authors is helmet gurnards. They have been regarded as the only family in the suborder Dactylopteroidei of the Scorpaeniformes but more recent molecular classifications put them in the order Syngnathiformes, in the superfamily Centriscoidea. They have been observed to "walk" along sandy sea floors while looking for crustaceans, other small invertebrates and small fish by using their pelvic fins. Like the true gurnards (sea robins), to which they may be related, they possess a swim bladder with two lobes and a "drumming muscle" that can beat against the swim bladder to produce sounds. They have heavy, protective scales and the undersides of their huge pectoral fins are brightly coloured, perhaps to startle predators. Most species are in the Indo-Pacific genus ' ...

Scorpionfish
The Scorpaenidae (also known as scorpionfish) are a family of mostly marine fish that includes many of the world's most venomous species. As their name suggests, scorpionfish have a type of "sting" in the form of sharp spines coated with venomous mucus. The family is a large one, with hundreds of members. They are widespread in tropical and temperate seas but mostly found in the Indo-Pacific. They should not be confused with the cabezones, of the genus '' Scorpaenichthys'', which belong to a separate, though related, family, Cottidae. Taxonomy Scorpaenidae was described as a family in 1826 by the French naturalist Antoine Risso. The family is included in the suborder Scorpaenoidei of the order Scorpaeniformes in the 5th Edition of ''Fishes of the World'' but other authorities place it in the Perciformes either in the suborder Scorpaenoidei or the superfamily Scorpaenoidea. The subfamilies of this family are treated as valid families by some authorities. Subfamilies and trib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodore Gill
Theodore Nicholas Gill (March 21, 1837 – September 25, 1914) was an American ichthyologist, mammalogist, malacologist and librarian. Career Born and educated in New York City under private tutors, Gill early showed interest in natural history. He was associated with J. Carson Brevoort in the arrangement of the latter's entomological and ichthyological collections before going to Washington D.C. in 1863 to work at the Smithsonian Institution. He catalogued mammals, fishes and mollusks most particularly although maintaining proficiency in other orders of animals. He was librarian at the Smithsonian and also senior assistant to the Library of Congress. He was elected as a member of the American Philosophical Society in 1867. Gill was professor of zoology at George Washington University. He was also a member of the Megatherium Club at the Smithsonian Institution in Washington, D.C. Fellow members frequently mocked him for his vanity. He was president of the American Associati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aulorhynchidae
Aulorhynchidae, the tube-snouts, is a small family of marine ray-finned fishes belonging to the suborder Gasterosteoidei in the order Scorpaeniformes. These fishes are found in the northern Pacific Ocean. Taxonomy Aulorhynchidae was first proposed as a family in 1861 by the American zoologist Theodore Gill, when he described ''Aulorhynchus flavidus'', placing it in a new monotypic family. This family is included in the suborder Gasterosteoidei of the order Scorpaeniformes in the 5th edition of ''Fishes of the World''. Other authorities treat the Gasterosteoidei as the infraorder Gasterosteales within the suborder Cottoidei or as a sister clade to the Zoarcales in the order Zoarciformes. Some authorities include the genus ''Aulichthys'' in the Hypoptychidae, but the 5th edition of ''Fishes of the World'' puts this taxon in the family Aulorhynchidae. Etymology Aulorhynchidae is derived from its type genus, ''Aulorhynchus'', the name of which is a combination of ''aulos'', meani ...

Franz Steindachner
Franz Steindachner (11 November 1834 in Vienna – 10 December 1919 in Vienna) was an Austrian Zoology, zoologist, ichthyologist, and herpetologist. He published over 200 papers on fishes and over 50 papers on reptiles and amphibians. Steindachner described hundreds of new species of fish and dozens of new amphibians and reptiles. At least seven species of reptile have been named after him. Work and career Being interested in natural history, Steindachner took up the study of fossil fishes on the recommendation of his friend Eduard Suess (1831–1914). In 1860 he was appointed to the position of director of the fish collection at the Naturhistorisches Museum, a position which had remained vacant since the death of Johann Jakob Heckel (1790–1857). (in German). Steindachner's reputation as an Ichthyology, ichthyologist grew, and in 1868 he was invited by Louis Agassiz (1807–1873) to accept a position at the Museum of Comparative Zoology at Harvard University.
