Lampriform
Lampriformes is an order of ray-finned fish. Members are collectively called lamprids (which is more properly used for the Lampridae) or lampriforms, and unite such open-ocean and partially deep-sea Teleostei as the crestfishes, oarfish, opahs, and ribbonfishes. A synonym for this order is Allotriognathi, while an often-seen, but apparently incorrect, spelling variant is Lampridiformes. They contain seven extant families which are generally small but highly distinct, and a mere 12 lampriform genera with some 20 species altogether are recognized. The scientific name literally means "shaped (like the) bright (one)", as "lampr-", meaning bright, comes from ''lampris'', the generic name for the opah. In contrast, most other living lampriforms are actually ribbon-like and not very similar to the disc-shaped opahs in habitus. They are, however, quite distinctly united by their anatomy, and the family's phylogeny, as well as the most ancient fossils of this order suggest the origina ...

Oarfish
Oarfish are huge, greatly elongated, pelagic lampriform fish belonging to the small family Regalecidae. Found in areas spanning from temperate ocean zones to tropical ones, yet rarely seen, the oarfish family contains three species in two genera. One of these, the giant oarfish (''Regalecus glesne''), is the longest bony fish alive, growing up to in length. The common name ''oarfish'' is thought to be in reference either to their highly compressed and elongated bodies, or to the now discredited belief that the fish "row" themselves through the water with their pelvic fins. The family name Regalecidae is derived from the Latin ''regalis'', meaning "royal". The occasional beachings of oarfish after storms, and their habit of lingering at the surface when sick or dying, make oarfish a probable source of many sea serpent tales. Although the larger species are considered game fish and are fished commercially to a minor extent, oarfish are rarely caught alive; their flesh is not w ...

Lampris
Opahs, also commonly known as moonfish, sunfish (not to be confused with Molidae), kingfish, redfin ocean pan are large, colorful, deep-bodied pelagic lampriform fishes comprising the small family Lampridae (also spelled Lamprididae). The family comprises two genera: ''Lampris'' (from the Ancient Greek ''λαμπρός'' : lamprós, "brilliant" or "clear") and the monotypic ''Megalampris'' (known only from fossil remains). The extinct family, Turkmenidae, from the Paleogene of Central Asia, is closely related, though much smaller. In 2015, ''Lampris guttatus'' was discovered to have near-whole-body endothermy in which the entire core of the body is maintained at around 5 °C above the surrounding water. This is unique among fish as most fish are entirely cold blooded or are capable of warming only some parts of their bodies. Species Two living species were traditionally recognized, but a taxonomic review in 2018 found that more should be recognized (the result of splitti ...

Crestfish
Crestfishes, family Lophotidae, are lampriform fishes found in most oceans. It consists of two extant and four extinct genera. They are elongated, ribbon-like fishes, silver in color, found in deep tropical and subtropical waters worldwide. Their scientific name is from Greek ''lophos'' meaning "crest" and refer to the crest (part of the dorsal fin A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through c ...) that emerges from the snout and head; this structure gives them their other name of unicorn fishes. The extant genera all possess ink sacs that open into their cloacae from which they can produce a cloud of black ink when threatened (as in many cephalopods).

Lampris Guttatus
''Lampris guttatus'', commonly known as the opah, cravo, moonfish, kingfish, and Jerusalem haddock, is a large, colorful, deep-bodied pelagic zone, pelagic Lampriformes, lampriform fish belonging to the family (biology), family Lampridae, which comprises the genus ''Lampris''. It is a pelagic fish with a worldwide distribution. While it is common to locations such as Hawaii and west Africa, it remains uncommon in others, including the Mediterranean. In the places where ''L. guttatus'' is prevalent, it is not a target of fishing, though it does represent an important commercial component of bycatch. It is common in restaurants in Hawaii. In Longline bycatch in Hawaii, Hawaiian longline fisheries, it is generally caught in deep nets targeting bigeye tuna. In 2005, the fish caught numbered 13,332. In areas where the fish is uncommon, such as the Mediterranean, its prevalence is increasing. Some researchers believe this a result of climate change. Much is still unknown about the dis ...

Ribbonfish
The ribbonfish are any lampriform fishes in the family Trachipteridae. These pelagic fish are named for their slim, ribbon-like appearance. They are rarely seen alive, as they typically live in deep waters, though are not bottom feeders. The perciform fish known as the red bandfish (''Cepola macrophthalma'') is sometimes referred to as ribbonfish, but it is unrelated to any ribbonfish in the Trachipteridae. They are readily recognized by their anatomy — a long, compressed, tape-like body, short head, narrow mouth and feeble teeth. A high dorsal fin occupies the whole length of the back; an anal fin is absent, and the caudal fin, if present, consists of two fascicles of rays of which the upper is prolonged and directed upwards. The pectoral fins are small, the pelvic fins composed of several rays, or of one long ray only. They have heavy spines along their lateral lines, and numerous lumps in the skin. Ribbonfish possess all the characteristics of fish living at very great ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Anatomy
Anatomy () is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times. Anatomy is inherently tied to developmental biology, embryology, comparative anatomy, evolutionary biology, and phylogeny, as these are the processes by which anatomy is generated, both over immediate and long-term timescales. Anatomy and physiology, which study the structure and function (biology), function of organisms and their parts respectively, make a natural pair of related disciplines, and are often studied together. Human anatomy is one of the essential basic research, basic sciences that are applied in medicine. The discipline of anatomy is divided into macroscopic scale, macroscopic and microscopic scale, microscopic. Gross anatomy, Macroscopic anatomy, or gross anatomy, is the examination of an ...

Crested Oarfish
The crested oarfish (''Lophotus lacepede'') is a species of crestfish in the family Lophotidae. It is an oceanodromous fish ranging from waters 0–92 meters deep, but may get stranded in shallow waters. Distribution and habitat The crested oarfish lives in warm seas near areas such as the Western Atlantic, Western Indian Ocean, Eastern Atlantic, and the Eastern Pacific within the oceanic and mesopelagic zone. Description and ecology The crested oarfish has maximum length of 200 centimeters, but are often are only found at 100 centimeters in length. It has an ink sack near the cloaca, and discharges ink out of it when it feels alarmed. Its prey consists of squids and fishes such as anchovies. It is oviparous, and lays planktonic eggs. Conservation The crested oarfish are likely found in marine protected areas, and has no known major threats towards it. No specific conservation measures have been made, and IUCN Red List has classified the fish as a 'least concern' species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetic Tree
A phylogenetic tree (also phylogeny or evolutionary tree Felsenstein J. (2004). ''Inferring Phylogenies'' Sinauer Associates: Sunderland, MA.) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree, indicating common ancestry. In a ''rooted'' phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of those descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. Internal nodes are generally called hypothetical taxonomic units, as they cannot be directly observed. Trees are useful in fields of biology such as bioinformatics, systematics, and phylogenetics. ''Unrooted'' trees illustrate only the relatedness of the leaf nodes and do not require the ancestral root to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
