The following [[Outline (list)|outline]] is provided as an overview of and topical guide to fish:

'''[[Fish]]''' – any member of a [[paraphyletic]] group of organisms that consist of all [[gill]]-bearing [[Aquatic animal|aquatic]] [[craniate]] animals that lack [[Limb (anatomy)|limbs]] with [[Digit (anatomy)|digits]].  Included in this definition are the living [[hagfish]], [[lamprey]]s, and [[chondrichthyes|cartilaginous]] and [[bony fish]], as well as various extinct related groups. Most fish are [[ectotherm]]ic ("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.<ref>{{cite journal |last=Goldman |first=K.J. |title=Regulation of body temperature in the white shark, ''Carcharodon carcharias'' |journal=Journal of Comparative Physiology |year=1997 |volume=167 |series=B Biochemical Systemic and Environmental Physiology |issue=6 |pages=423–429 |doi=10.1007/s003600050092 |s2cid=28082417 |url=http://www.mendeley.com/research/temperature-and-activities-of-a-white-shark-carcharodon-carcharias/ |accessdate=12 October 2011 |archive-url=https://web.archive.org/web/20120406114844/http://www.mendeley.com/research/temperature-and-activities-of-a-white-shark-carcharodon-carcharias/ |archive-date=6 April 2012 |url-status=dead }}</ref><ref>{{cite journal |last2=Lawson |first2=K.D. |last1=Carey |first1=F.G. |title=Temperature regulation in free-swimming bluefin tuna |journal=Comparative Biochemistry and Physiology A |date=1 February 1973 |volume=44 |issue=2 |pages=375–392 |doi=10.1016/0300-9629(73)90490-8 |pmid=4145757}}</ref>  Fish are abundant in most bodies of water. They can be found in nearly all aquatic environments, from high mountain streams (e.g., [[Salvelinus|char]] and [[gudgeon (fish)|gudgeon]]) to the [[abyssal zone|abyssal]] and even [[hadal zone|hadal]] depths of the deepest [[ocean]]s (e.g., [[cusk-eel]] and [[snailfish]]). At 32,000 species, fish exhibit greater species diversity than any other group of vertebrates.<ref>[[FishBase]]: [http://www.fishbase.org/search.php February 2011 Update.] Retrieved 24 May 2011.</ref>
