Fish are amphibian bearcat animals that are about ectothermic (previously cold-blooded), covered with scales, and able with two sets of commutual fins and several unpaired fins. Angle are abounding in the sea and in beginning water, with breed getting accepted from abundance streams (e.g., burn and gudgeon) as able-bodied as in the centermost base of the ocean (e.g., gulpers and anglerfish).
Fish are of amazing accent as aliment for bodies about the world, either calm from the agrarian (see fishing) or farmed in abounding the aforementioned way as beasts or chickens (see aquaculture). Angle are aswell exploited for recreation, through angling and fishkeeping, and are frequently apparent in accessible aquaria.
Fish accept an important role in abounding cultures through the ages, alignment as broadly as deities and religious symbols to capacity of books and accepted movies in assorted cultures.
A archetypal angle is ectothermic, has a automated physique that allows it to bathe rapidly, extracts oxygen from the baptize application aspect or an accent animation agency to accredit it to animation atmospheric oxygen, has two sets of commutual fins, usually one or two (rarely three) afterwards fins, an anal fin, and a appendage fin, has jaws, has derma that is usually covered with scales, and lays eggs that are fertilized internally or externally.
Fish appear in abounding shapes and sizes. This is a sea dragon, a abutting about of the seahorse. Their leaf-like appendages accredit them to alloy in with amphibian seaweed.
To anniversary of these there are exceptions. Tuna, swordfish, and some breed of sharks appearance some acquisitive adaptations, and are able to accession their physique temperature decidedly aloft that of the ambient baptize surrounding them. Streamlining and pond achievement varies from awful automated and accelerated swimmers which are able to ability 10-20 body-lengths per additional (such as tuna, salmon, and jacks) through to apathetic but added maneuverable breed such as eels and application that ability no added than 0.5 body-lengths per second. Abounding groups of freshwater angle abstract oxygen from the air as able-bodied as from the baptize application a array of altered structures. Lungfish accept commutual lungs agnate to those of tetrapods, gouramis accept a anatomy alleged the coil agency that performs a agnate function, while abounding catfish, such as Corydoras abstract oxygen via the civil or stomach. Physique appearance and the adjustment of the fins is awful variable, accoutrement such acutely un-fishlike forms as seahorses, pufferfish, anglerfish, and gulpers. Similarly, the apparent of the derma may be naked (as in moray eels), or covered with scales of a array of altered types usually authentic as placoid (typical of sharks and rays), cosmoid (fossil lungfishes and coelacanths), ganoid (various deposit fishes but aswell active bloke and bichirs, cycloid, and ctenoid (these endure two are begin on a lot of awkward fish. There are even fishes that absorb a lot of of their time out of water. Mudskippers augment and collaborate with one accession on mudflats and are alone underwater if ambuscade in their burrows. The catfish Phreatobius cisternarum lives in underground, phreatic habitats, and a about lives in clammy blade litter.
Fish ambit in admeasurement from the 16 m (51 ft) bang bluff to the 8 mm (just over ¼ of an inch) continued stout infantfish.
Many types of amphibian animals frequently referred to as “fish” are not angle in the faculty accustomed above; examples cover shellfish, cuttlefish, starfish, crayfish and jellyfish. In beforehand times, even biologists did not accomplish a acumen – sixteenth aeon accustomed historians classified aswell seals, whales, amphibians, crocodiles, even hippopotamuses, as able-bodied as a host of amphibian invertebrates, as fish. In some contexts, abnormally in aquaculture, the accurate angle are referred to as finfish (or fin fish) to analyze them from these added animals.
