Syngnathiformes
The Syngnathiformes are an order of ray-finned fishes that includes the leafy seadragons, sea moths, trumpetfishes and seahorses, among others.FishBase (2005)Order Summary for Syngnathiformes Version of 2005-FEB-15. Retrieved 19 Aug 2008. These fishes have generally elongate, narrow bodies surrounded by a series of bony rings, with small, tubular mouths. The shape of their mouth—at least, in syngnathids—allows for the ingestion of prey at close range via suction. Many species of Syngnathiformes also employ strategic camouflage (such as cryptic coloration and overall physical form) to hunt successfully and gain closer access to prey, as well as to protect themselves from larger predators. Several groups, for example, live among seaweed, not only swimming with their bodies aligned vertically (to blend in with the floating plant matter) but have also developed physical features that mimic the seaweed. The pygmy seahorses are among the smallest of all syngnathids, with most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trumpetfish
The trumpetfishes are three species of highly specialized, tubularly-elongated marine fishes in the genus ''Aulostomus'', of the monogeneric family Aulostomidae. The trumpetfishes are members of the order Syngnathiformes, together with the Syngnathidae, seahorses and the similarly built, closely related Fistulariidae, cornetfishes. The generic name, ''Aulostomus'', is a composite of two Greek words: ''aulos'', meaning flute, and ''stoma'', meaning mouth, because the species appear to have tubular snouts. "Flutemouth" is another less-common name for the members of the family (although this word is more often used to refer to closely related cornetfishes of the family Fistulariidae). Trumpetfishes are found in tropical waters worldwide, with two species in the Atlantic and one in the Indo-Pacific. They are mostly demersal reef-dwellers, where one species seems to prefer rocky substrate. They are relatively large for reef fish, where they reach almost 1 m in length. Bodies of trum ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Syngnathid
The Syngnathidae is a family of fish which includes seahorses, pipefishes, and seadragons ('' Phycodurus'' and ''Phyllopteryx''). The name is derived from (), meaning "together", and (), meaning "jaw". The fused jaw is one of the traits that the entire family have in common. Description and biology Syngnathids are found in temperate and tropical seas across the world. Most species inhabit shallow, coastal waters, but a few are known from the open ocean, especially in association with sargassum mats. They are characterised by their elongated snouts, fused jaws, the absence of pelvic fins, and by thick plates of bony armour covering their bodies. The armour gives them a rigid body, so they swim by rapidly fanning their fins. As a result, they are relatively slow compared with other fish but are able to control their movements with great precision, including hovering in place for extended periods. Uniquely, after syngnathid females lay their eggs, the male then fertilizes and ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Moth
The seamoths make up a family of ray-finned fishes, the Pegasidae, within the order Syngnathiformes. They are named for Pegasus, a creature from Greek mythology. Seamoths are notable for their unusual appearance, including flattened bodies, the presence of large, wing-like, pectoral fins, a long snout, and a body encased in thick, bony plates. They are found primarily in coastal tropical waters of the Indo-Pacific. Biology Seamoths have modified pelvic fins that allow them to "walk" across the sea bottom where they live. Their jaws are ventral, located behind their long rostrum, and are toothless. Their mouth is highly specialized, and can form a tube-like mouth used to suck worms and other small invertebrates from their burrows. They periodically molt their skin, perhaps as often as every five days. Conservation ''Pegasus lancifer'' and the two ''Eurypegasus'' species are listed as Least Concern by the IUCN, while the remaining species of seamoth remain Data Deficient A dat ...

Gasterosteoidei
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 a ...

Eekaulostomus
''Eekaulostomus'' is an extinct genus of marine fish from the Paleocene of Chiapas, Mexico. It contains one species, ''E. cuevasae'', and is the only member of the family Eekaulostomidae. ''Eekaulostomus'' was a syngnathiform, a member of the same order as modern trumpetfish, cornetfish, pipefish, and seahorses. It can be distinguished from other syngnathiforms by the prominent scutes covering its body, giving it an armored appearance. Its exact phylogenetic placement among the sygnanthiforms is debated, although it is known to belong to the "long-snouted" group (Syngnathoidei); it was initially recovered as allied with the trumpetfish superfamily ( Aulostomoidea), but more recent studies have found it to be more closely related to the pipefish superfamily ( Syngnathoidea). The only known specimen of ''Eekaulostomus'' was found in exposures of the Tenejapa-Lacandón Unit in the Belisario Domínguez quarry near the ancient Mayan city of Palenque. It inhabited the Caribbean re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pygmy Seahorse
The pygmy seahorses comprise several species of tiny seahorse in the syngnathid family or Syngnathidae (seahorses and pipefish). Family Syngnathidae is part of order Syngnathiformes, which contains fishes with fused jaws that suck food into tubular mouths. Pygmy seahorses are found in Southeast Asia in the Coral Triangle area. They are some of the smallest seahorse species in the world, typically measuring less than in height.Lourie, S.A., Foster, S.J., Cooper, E.W.T. and Vincent, A.C.J.

Seahorse
A seahorse (also written ''sea-horse'' and ''sea horse'') is any of 46 species of small marine Osteichthyes, bony fish in the genus ''Hippocampus''. The genus name comes from the Ancient Greek (), itself from () meaning "horse" and () meaning "sea monster" or "sea animal". Having a head and neck suggestive of a horse, seahorses also feature segmented bony armour, an upright posture and a curled prehensile tail. Along with the pipefishes and seadragons (''Phycodurus'' and ''Phyllopteryx'') they form the family Syngnathidae. Evolution and fossil record Anatomical evidence, supported by molecular, physical, and genetic evidence, demonstrates that seahorses are highly modified pipefish. The fossil record of seahorses, however, is very sparse. The best known and best studied fossils are specimens of ''Hippocampus guttulatus'' (though literature more commonly refers to them under the synonym of ''H. ramulosus''), from the Marecchia River formation of Rimini Province, Italy, ...

10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' (Latin; the English title is ''A General System of Nature'') is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of ''Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
