HISTORY OF FISH look for are a paraphyletic host of organisms that lie in of all gill-bearing aquatic vertebrate (or craniate) animals that neediness limbs with digits. Included in this definition are the living hag angle, lampreys, and rubbery and bony tilt, as well as various nonextant related groups. around fish are ect differentmic ( frigid), allowing their body temperatures to straggle as ambient temperatures change, though roughly of the large vigorous swimmers like white shark and tuna fish stand devote a higher core temperature. tilt are exuberant in most bodies of water. They can be found in nearly all aquatic environments, from high mountain streams (e.g., melanise and gudgeon) to the abyssal and even heal depths of the deepest marines (e.g., gulpers and anglerfish). At 32,000 species, fish establish greater species diversity than any other class of vertebrates. Fish, particularly as food, are an important choice worldwide. Commercial and subsistence fi shers bleed fish in wild fisheries (see fishing) or farm them in ponds or in cages in the ocean (see aquaculture). They are similarly caught by recreational fishers, kept as pets, raised by fish keepers, and exhibited in public aquaria. Fish have had a role in culture by means of the ages, serving as deities, religious symbols, and as the subjects of art, books and movies.

Because the term fish is defined negatively, and excludes the tetrapods (i.e., the amphibians, reptiles, birds and mammals) which descend from within the same ancestry, it is paraphyletic, and is not considered a appropriate grouping in systema tic biology. The tralatitious term Pisces (! also ichthyic) is considered a typological, but not a phyletic classification. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Welsh period. Although they lacked a true spine, they possessed notochords which allowed them to be more flying than their invertebrate counterparts. Fish would continue to arise through the Paleozoic...If you expect to get a full essay, read it on our website: OrderCustomPaper.com
