'''Fish locomotion''' is the various types of [[animal locomotion]] used by [[fish]], principally by [[aquatic locomotion|swimming]]. This is achieved in different groups of fish by a variety of mechanisms of propulsion, most often by wave-like lateral flexions of the fish's body and tail in the water, and in various specialised fish by motions of the [[fish fin|fin]]s. The major forms of locomotion in fish are:
* Anguilliform<!--don't link, this redirects here!-->, in which a wave passes evenly along a long slender body;
* Sub-carangiform, in which the wave increases quickly in amplitude towards the tail;
* Carangiform, in which the wave is concentrated near the tail, which oscillates rapidly;
* Thunniform, rapid swimming with a large powerful crescent-shaped tail; and
* Ostraciiform, with almost no oscillation except of the tail fin.
More specialized fish include movement by pectoral fins with a mainly stiff body, opposed sculling with dorsal and anal fins, as in the [[Molidae|sunfish]]; and movement by propagating a wave along the long fins with a motionless body, as in the [[Gymnotiformes|knifefish]] or [[Notopteridae|featherbacks]].

In addition, some fish can variously "walk" (i.e., crawl over land using the pectoral and pelvic fins), [[burrow]] in mud, leap out of the water and even [[gliding flight|glide]] temporarily through the air.
