Fish locomotion

Ways that fish move around

Fish locomotion is the various types of animal locomotion used by fish, principally by 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 fins. The major forms of locomotion in fish are:Anguilliform, 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.
