Aerial photographs of swimming dolphins. (a) An actual leaping sequence; (b) several mother-calf pairs swimming at high speed. In (a), the calf performs a bad leap, resulting in a large splash (frame 4), slowing it down and losing the close connection required for drafting. The data in (b) are the basis for several of the entries in Table 4.
