They need rudders and propellers. Look closely at a whale or dolphin â youâll see that many have a dorsal fin, the fin that sticks up from the back of the animal. Scientists believe that the dorsal fin acts as a stabilizer or a rudder. You might think that the dorsal fin has bones in it, like the fins on fish. But the whaleâs dorsal fin has no bones.
