Fish
A fish is any member of a paraphyletic group of organisms that consist of all gill-bearing aquatic craniate 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. Most fish are ectothermic ("cold-blooded"), allowing their body temperatures to vary as ambient temperatures change, though some of the large active swimmers like white shark and tuna can hold a higher core temperature. Fish are abundant in most bodies of water. They can be found in nearly all aquatic environments, from high mountain streams (e.g., char and gudgeon) to the abyssal and even hadal depths of the deepest oceans (e.g., gulpers and anglerfish). At 32,000 species, fish exhibit greater species diversity than any other group of vertebrates.

Famous quotes containing the word fish:
“Slow, slow, as a fish she came,
Slow as a fish coming forward,
Swaying in a long wave;
Her skirts not touching a leaf,
Her white arms reaching towards me.”
—Theodore Roethke (1908–1963)
“To me heaven would be a big bull ring with me holding two barrera seats and a trout stream outside that no one else was allowed to fish in and two lovely houses in the town; one where I would have my wife and children and be monogamous and love them truly and well and the other where I would have my nine beautiful mistresses on nine different floors.”
—Ernest Hemingway (1899–1961)
“The laying of fish on the embers,
the taste of the fish,
the feel of the texture of bread,
the round and the half-loaf,
the grain of a petal,
the rain-bow and the rain.”
—Hilda Doolittle (1886–1961)
