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:
“My face is muffled in my mother’s clothing. Her rhinestones injure me. See: my feet are going. Fish flee the forefinger of my aunt. The sun streams over the geraniums. What has this to do with what I feel, with what I am.”
—William Gass (b. 1924)
“When the city gate catches fire, it’s the fish in the moat who suffer.”
—Chinese proverb.
“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)
