HISTORY OF FISH lean are a paraphyletic stem of organisms that lie in of all gill-bearing aquatic vertebrate (or craniate) animals that insufficiency limbs with digits. Included in this definition are the living hag slant, lampreys, and rubbery and bony fish, as well as various out(p) related groups. around fish are ect oppositemic ( moth-eaten), allowing their body temperatures to straggle as ambient temperatures change, though almost of the large vigorous swimmers like white shark and tuna stand devote a grittyer core temperature. angle 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 maritimes (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 fishe rs 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 finished 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 non considered a appropriate grouping in systematic b iology. The tralatitious term Pisces (also ! ichthyic) is considered a typological, but not a phylogenetic 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.
