Pisces are gill-bearing water cranes that are lacking extremities with numbers..... Among this definitions are live molluscs, lamprey, cartilage fish and bonefish as well as various endangered groups. Tetrapodes appeared in rag fish so that they are also fish. Fish, however, are conventionally made paraphyletically by eliminating the tetrapodes (i.e. amplibians, terrestrials, mires, poultry, birds as well as moths, all of which are of the same descent).

Since in this way the concept "fish" is negative in the definition of a para-phyletic group, it is not regarded in systems biological studies as a functional grouping. Fish (also ichthyes) is a typeological, but not a phylogenetical grouping. At first, the fish were softbody chords, which first occurred in Cameroon.

Though lacking a real spinal column, they had disochords that enabled them to be more spry than their invertebrates mates. The fish continued to develop during the Palaeozoic and spread in a multitude of shapes. Several Palaeozoic fish invented an outer armour to protect them from carnivores. Fish with pines first emerged in the Silura age, after that many (e.g. sharks) became huge naval carnivores and not only preys of arthropod.

Pisces are an important global human resources, especially as a foodstuff. Comercial and subistence fishermen fish in wildfishing (see fishing) or breed them in pools or sea baskets (see aquaculture). Over the centuries fish have played a part in the civilization, acting as gods, sacred icons and themes of arts, literature and films.

The early fish from the world of fossils are presented by a group of small, pine free, armoured fish known as Eastracoderms. Pine less fish lines are mostly dead. The lamprey, a still existing Klade, can approach the old Vorkieferfischen. Pisces may have developed from a critter resembling a coral-like syringe whose nymphs in many ways look like crude fish.

Fish's first forefathers may have maintained the larvae shape into adult life (as some marine sheaths do today), although perhaps the opposite is the case. Pisces are a para-phyletic group, i.e. every cladding that contains all fish also contains the non-piscesetrapods. Several paleontologists claim that Conodonta, because they are chords, are crude fish.

Fish " is the most accurate description of any non-tetrapodic cranial species (i.e. an organ with a cranium and in most cases a spine) that has lifelong lobes and whose extremities, if any, are in the form of flippers. 14 ] Unlike groups such as fowl or mammal, fish are not a Klade, but a para-phyletic accumulation of taxesa, among them hagfish, lamprey, shark and stingrays, radiation fish, Celacanths and lungfishes.

In fact, lungfishes and Coelacanth's are close cousins of the tetrapod (such as the mammal, bird, amphibian, etc.) than of other fish such as stingray finfish or shark, so that the last joint forefather of all fish is also an forefather of the tetrapod. The use of the concept of "fish" as a biologic group must be prevented because para-phyletic groups are no longer recognized in this area.

However, many species of water creatures generally known as" fish" are not fish in the above meaning; for example, crustaceans, squids, starfishes, crabs and molluscs. Formerly, even the biologist made no difference - even harbour seals, cetaceans, amphibia, hippos, crocodiles and even a large number of invertebrate water creatures were categorized as fish by nature-historists.

17 ] However, according to the above definitions, all invertebrates, as well as porpoises and porpoises, are not fish. There are some situations, especially in the field of fish farming, where the real fish are called finfishes (or finfish) to differentiate them from these other species. They are ectothermal, have a streamline shape for fast swim s, extract air from the waters with louvers or use an additional respiratory system to breath air pollutants, have two pairs of flippers, usually one or two (rarely three) back flippers, an anus and a caudal flipper, have pine, have scaly skins and lay cuticles.

The sizes of the fish vary from the giant 16-metre sharks to the minute 8-millimeter child fish. The majority of fish transfer gas through the lobes on both sides of the throat. Lamellae are made of filamentary structure, the so-called threads. Pisces change gas by dragging oxygenated waters through their mouth and pump them over their lough.

With some fish, the flow of tapillary artery is in the opposite flow to the flow of sea air, leading to a counterflow-change. Several fish, such as shark and lamprey, have several sills. Bonefish, however, have a unique opening in the gills on each side. The opening is concealed under a protecting osseous envelope known as the opera. Fish bowl is directed downwards, with a look at the lips.

Fishes from several groups can survive out of the sea for a long time. Amphibian fish such as the mudhopper can stay on shore for up to several days and move,[doubtfully - discuss] or in stagnating or otherwise oxygen-poor sea. Most of these fish can breath through different breathing apparatus.

Several fish have developed so-called additional respiratory systems that draw off atmospheric gas. Maze fish (e.g. Guramis and Betta) have a maze body above their lobes, which fulfils this grouping. Some other fish have labyrinth-like shapes and functions, especially snakehead fish, zander and the Clariidae fishes.

Breathable aeration is particularly suitable for fish that live in flat, seasonal changing bodies of aquatic life, in which the level of fresh sea breeze can decrease in season. Fishes that depend exclusively on solute oxigen, such as bass and cichlid, quickly choke, while airbreathers live much longer, in some cases in muddy, moist conditions.

Some airbreathing fish are most able to live in moist caves for a few days without using fresh waters and to reach a state of motivation (summer hibernation) until the waters return. Fishes have a continuous cycle. Most fish have a four-part cardioid, two of which are compartments and an in/outlet.

Pine allows fish to feed on a large number of foodstuffs, among them plant and other species. Pisces take up nourishment through the oral cavity and degrade it in the oesophagus. Nutrition is further absorbed in the gastric system and in many fish it is converted into finger-shaped bags named fyloric capeca, which release digestion-enzyme and take up nutrition.

Like in many marine species, most fish give off their nitrogen-containing waste as amonia. Seawater fish have a tendency to loose sea salt through osmotic action. On the contrary, fresh fish have a tendency to produce osmotic waters. A number of fish have specifically adjusted cardioids that differ in their functions and allow them to move from fresh to salt sea.

Fish dandruff comes from the messoderm (skin); its texture can be similar to that of a tooth. Fishbrains are subdivided into several areas. 29 ] The oil factoric lobe is very large in fish that mainly chase after odor, such as hagfishes, e.g. mallards, welspers. For fish, telencephalons are mainly involved in the formation of odours.

The majority of fish have sophisticated sensory system. Almost all fish in natural light have colour vision at least as good as that of humans (see seeing in fish). Most fish also have chemo-receptors, which are the cause of exceptional sensations of flavour and aroma. Though they have hearing, many fish can't heed well.

The most fish have delicate receivers that make up the sideline system, which recognizes soft flows and vibration and senses the movement of fish and preys in the vicinity. 31 ] Some fish, such as wels and shark, have the ampoules of Lorenzini, bodies that recognize low electrical current in the order of millivolts.

Other fish, such as the Latin America electrofish Gymnotiformes, can generate low electrical current, which they use in navigating and people-communicating. Seeing is an important sensorial system for most fish types. Fisheyes resemble those of vertebrate animals such as poultry and mammal, but have a sphere-shaped orb.

The retina generally has both chopsticks and pins (for skotopic and photo vision), and most types have color vision. 2. Certain fish can see ultra-violet and other polarised lights. Among the fish without jaws, the suckling eye has well formed eyeballs, while the slime eel has only crude eye spots. 34 ] The eyesight of the fish shows an adjustment to their optical surroundings, e.g. deep-sea fish have big fishes' eye suitable for the darkness.

Noise is an important sensorial system for most fish types. Pisces feel noises over their side contours and ear. The majority of fish move by alternating contraction of coupled muscle on both sides of the spine. When every turn hits the dorsal flipper, a backward thrust is exerted on the waters, which, in combination with the flippers, drives the fish forward.

Fish streamline reduces the frictions from the sea. As the tissues of the human organism are thicker than those of the sea, fish must make up for the differences, otherwise they will be sinking. A lot of bonefish have an inner organs, a swimming bubble, which regulates its lift through the handling of air.

The fish' reproductional system includes the testis and ovary. Most of the varieties are similar sized coupled bodies that can be partly or completely melded. The fish can have three different ovaries: gymnovaric, gymnasovaric or cystovaric. Several fish, such as the Californian sheep head, are hermaphrodite, which have both testis and ova either at different stages of their lifecycle or, as in villages, have them both.

More than 97% of all known fish are ovipar,[46] which means that the egg develops outside the mother's skull. Oviiparous fish are for example lemon, gold fish, cichlid, tunnel fish and eel. Most of these types are fertilised outside the mother's organism, with the males and females releasing their germ cells into the ambient wells.

Nonetheless, some of these fish practise in vitro fertilisation when the man uses some species of entromittent organ in order to supply semen into the woman's female genital opening, in particular the oviparous sharks, such as the dogfish, and oval jets, such as ices. Sea fish can make large quantities of egg, which are often discharged into the open head of mud.

Ovarian of fish (Corumbat√°). Freshly born young animals of the ovaries are referred to as nymphs. Viparous fish have a relatively brief larva time (usually only a few weeks) and the nymphs are growing quickly and changing their look and texture (a phenomenon known as metamorphosis) into young animals. Egg development in the egg viviparous fishes inside the mother's system after insemination, but little or no food is received directly from the eggyolks.

Known instances of ovoviviprous fish are guppys, angelsharks and cormorants. Aquarians call avoviviparous and aviviparous fishes livebearing. A number of fish types generate sound by using specialised muscle contractions and bladder vibration. Immunological tissues differ depending on the fish variety. 60 ] The fish without jaws (lampreys and hagfish) lack real lymphatic tissues.

The fish depend on the lymphatic tissues of other organisms to generate immunocytes. Chondrophic fish (sharks and rays) have a more developed immunity system. Chondrosteic fish (sturgeon, paddle fish and bichire) have an important site for the secretion of Granulocyte within a body associated with the cerebral membrane (membranes around the CNS ) and their hearts are often coated with tissues containing Lymphocyte, Rebicular Cell and a small number of Macrophage.

Over-fishing is a great menace to food fish such as Atlantic Cod and Thuna. This kind of outbreak does not mean that the fish has become extinct, but only that it can no longer maintain a population. Introducing alien fish has taken place in many habitat areas. The Nile bass slowly destroyed the 500 different types of cichlids.

81 ]Carp, snakehead,[82]Tilapia, bass, brookrout, brookrout, brookrout, and lamprey are further samples of fish that have created difficulties through their introduction to foreign habitats. projects in a country town. In the course of time, man has used fish as a nutritional resource. Most of the fish proteins have been produced by fishing for game.

Yet fish culture or fish breeding, which has been practised since around 3,500 B.C., is becoming more and more important in China[83]. Overall, it is thought that about one in six of the world's proteins is supplied by fish. Similarly, fish were bound to the market. Trapping fish for nutritional or sporting purposes is referred to as fish, while the organised efforts of man to fish are referred to as fisheries.

84 ] The total global fishing output is around 154 million tonnes per year,[85] with favourite fish such as herrings, hake, cod, anchovies, bluefin tuna, flounders and squid. The notion of fishing, however, is widespread and comprises more than just fish, such as molluscs and shellfish, which are often referred to as "fish" when used as diet.

For almost as long fish have been recognised as a fountain of natural beauties as they are used in caving, reared as fish in pools and exhibited in aquaria in homes, office and theatres. The technique of fish ing-especially fish caught at an "angle" (hook).

Fishermen must choose the right catch, throw precisely and bring it back at the right pace, taking into account sea and meteorological condition, types, fish reaction, season and other facts is a Christmas tree ancestor. is a Christmas tree, which means that the fish that uses it is a Christ. The book of Jonah, a work of Judaic writing probably dating from the 4th millennium BC, swallows the key character, a prophesy called Jonah, by a huge fish after he was tossed over board by the crews of the vessel on which he is sailing.

89 ][90][91] The fish will vomit Jonah later after three workdays ashore. 94 ] Early Christians used the Ichthyas, a sign for a fish to depict Jesus,[87][88] because the Grecian term for fish, ????? Ichthy's, could be used as an abbonym for "?????? ???????, ???? ????, ?????". Buddhism's Buddhist denomination of fish symbolizes luck because they have total liberty of motion in the waters.

Pisces play an important role in arts and literary works, in film such as Finding Nemo and novels such as The Old Man and the Sea. Big fish, especially shark, were often the object of scary and thrilling flicks, especially the novel Jaws, which produced a range of eponymous flicks, which in turn inspire similar flicks or spoofs like Shark Tale and Snakehead Terror.

Similar to the shark, they are shown in movies like Piaranha, but against the common opinion the red-bellied biranha is actually a generally shy type of scavengers, which can't hurt people. Pisces are used as a solitary substantive or plurals to describe several specimens of a particular type.

Fish are used to describe different types or groups of types. 98 ][99][100] One could say that a lake containing a unique fish stock had 120 fish. However, if the lake had 120 fish of three different types, it would be said to have three fish. A fish's rigorous organic concept, above, is sometimes referred to as real fish.

Real fish are also known as fins to differentiate them from other fish that are picked in fishing or fish farming. Anchovy, herring, and silverflakes are classical fish shoals.
