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:
“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 beasts, the fishes, and the winged fowls
Are their males’ subjects and at their controls:
Man, more divine, the master of all these,
Lord of the wide world and wild watery seas,
Indued with intellectual sense and souls,
Of more pre-eminence than fish and fowls,
Are masters to their females, and their lords:
Then let your will attend on their accords.”
—William Shakespeare (1564–1616)
“Until they saw, over the mists
of Venus, two fish creatures stop
on spangled legs and crawl
from the belly of the sea.
And from the planet park
they heard the new fruit drop.”
—Anne Sexton (1928–1974)
