  • Definition: Body/caudal fin propulsion, characteristic of tunas, also found in several lamnid sharks. Virtually all the sideways movement is in the tail and the region connecting the main body to the tail (the peduncle). The tail itself tends to be large and crescent shaped. This form of swimming enables these fish to chase and catch prey more easily due to the increase in speed of swimming, like in barracudas.
