Definition: (Quadrupedal jumping) Progression composed of a series of leaps in which the hind legs supply the chief propulsive force, lifting the body completely from the ground and forward. The fore feet touch the ground simultaneously or in close sequence; the body rolls forward over these as in a vault; the hind feet, overstepping the fore feet, at least in greatest speed, come down next and again lift the body forward
Definition: Body/caudal fin propulsion, retaining eel-like body movements and exploiting interactions between the sidewash from an anterior median fin with the next posterior fin, increasing its effective angle of attack
Definition: a type of pectoral-fin-based swimming, also known as mobuliform locomotion. Lower frequency than fin undulation; can be described as the production of less than half a wave on the fin, similar to a bird wing flapping. Pelagic stingrays use oscillatory locomotion.
