Syngnathoidei
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 "-f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Solenostomidae
''Solenostomus'', also known as the ghost pipefishes, false pipefishes or tubemouth fishes, is a genus of fishes in the order Syngnathiformes. ''Solenostomus'' is the only genus in the family Solenostomidae, and includes six currently recognized species.Family SolenostomidaFishBase. Accessed 1 February 2015. Ghost pipefishes are related to pipefishes and seahorses. They are found in tropical waters of the Indo-Pacific. The animals, none of which are longer than , float near motionlessly, with the mouth facing downwards, around a background that makes them nearly impossible to see. They feed on tiny crustaceans, sucked inside through their long snout. They live in open waters except during breeding, when they find a coral reef or muddy bottom, changing color and shape to minimize visibility. In many respects, they are similar to the pipefishes, but can be distinguished by the presence of pelvic fins, a prominent, spiny, dorsal fin, and star-shaped plates on the skin. Unlike true ...

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 ...

Stickleback
The sticklebacks are a family of ray-finned fishes, the Gasterosteidae which have a Holarctic distribution in fresh, brackish and marine waters. They were thought to be related to the pipefish and seahorses but are now thought to be more closely related to the eelpouts and sculpins. Taxonomy The stickleback family, Gasterosteidae, was first proposed as a family by the French zoologist Charles Lucien Bonaparte in 1831. It was long though that the sticklebacks and their relatives made up a suborder, the Gasterosteoidei, of the order Gasterostiformes with the sea horses and pipefishes making up the suborder Syngnathoidei. More recent phylogenetic work has shown that the Gaterosteoidei is more closely related to the Zoarcoidei and the Cottoidei, which means that this taxon would belong in the order Scorpaeniformes. 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 ord ...

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 ...

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

Syngnathoidea
Syngnathoidea is a superfamily of the pipefish order Syngnathiformes. It is divided into two families, the speciose pipefish Syngnathidae, which includes the sea horses and monotypic Solenostomidae, the ghost pipefishes, which has just five species. The superfamily occurs worldwide in tropical, subtropical and temperate seas, especially in coastal waters around rock and coral reefs and among sea weed and sea grass beds. However, there are also pelagic species of pipefish and even freshwater species. In total the superfamily comprises in excess of 50 genera and nearly 300 species. Classification The superfamily Syngnathoidea contains the following families and subfamilies: *Superfamily Syngnathoidea ** Family Solenostomidae Nardo, 1843 (ghost pipefishes) ** Family Syngnathidae Bonaparte, 1831 (pipefishes and seahorses) *** Subfamily Syngnathinae Bonaparte, 1831 (pipefishes) *** Subfamily Hippocampinae The Hippocampinae are a subfamily of small marine fishes in the family ...

Pegasoidea
The seamoths make up a family of 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.Herold D, and Clark E. 1993. Monogamy, spawning, and skin-shedding of the seamoth, ''Eurypegasus draconis'' (Pisces: Pegasidae).

Syngnathus Acus
The greater pipefish (''Syngnathus acus'') is a pipefish of the family Syngnathidae. It is a seawater fish and the type species of the genus ''Syngnathus''. Etymology The genus name ''Syngnathus'' derives from the Greek, ''syn'', ''symphysis'' meaning ''grown together'' and ''gnathos'' meaning ''jaw''. The Latin species name ''acus'' means ''needle''. Description The greater pipefish has a long segmented armoured body, angular in cross section and stretching up 45 cm long with its stiff appearance. It ranges a color brown to green in with broad alternating light and dark hue along it. Its customized by a long snout with mouth on end and a slight hump on the top of the body just behind the eyes. The fish is generally 33 cm to 35 cm in length with a reported maximum length of 47 cm. They are almost square in each segment of the body, and known to feel rigid when handled. The greater pipefish has distinctive body rings which are a sandy brown with darker bar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fistulariidae
The cornetfishes or flutemouths are a small family, the Fistulariidae, of extremely elongated fishes in the order Syngnathiformes. The family consists of a single genus, ''Fistularia'', with four species, found worldwide in tropical and subtropical marine environments. Ranging up to in length, cornetfishes are as thin and elongated as many eels, but are distinguished by very long snouts, distinct dorsal fin, dorsal and anal fins, and forked caudal fins whose center rays form a lengthy filament. The lateral line is well-developed and extends onto the caudal filament. They generally live in coastal waters or on coral reefs, where they feed on small fishes, crustaceans, and other invertebrates. Cornetfish are of minor interest for fishing, and can be found in local markets within their range. Species Currently, four recognized species are placed in this genus: * ''Fistularia commersonii'' Eduard Rüppell, Rüppell, 1838 (blue-spotted or smooth cornetfish) * ''Fistularia corneta' ...

Paraphyletic
In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its descendants, excluding a few Monophyly, monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of Synapomorphy and apomorphy, synapomorphies and symplesiomorphy, symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia (reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
