Pectoral fins of sharks and flippers of dolphins are analogous organs. Pectoral fins of sharks are not pentadactyle. The flippers of dolphins are pentadactyle.
Thus basic structure of pectoral fins of sharks and flippers of dolphins are different but both are useful in swimming and perform the same function
