Fish locomotion

（重定向自Thunniform）
Boxfish are the classic biological example of MPF swimming because they are not well streamlined and use primarily their pectoral fins for thrust production.
Sardines use body-caudal fin propulsion to swim and hold their pectoral, dorsal, and anal fins flat against the body, creating a more streamlined body and reducing drag.
Flying fish are able to achieve sufficient lift to glide above the surface of the water thanks to their enlarged pectoral fins.

The prevailing type of fish locomotion is swimming in water. In addition, some fish can "walk", i.e., move over land, burrow in mud, and glide through the air.
