The researchers pick out distinguishing marks (which may also be scars -scars on the white portion appear dark and scars on the darkportions of the tails appear white). A whale named “Cat’s Paw” has a mark on her tail that looks just like a paw print. Since humpbacks lift their tails out of the water when they dive, researchers can see and photograph the flukes, allowing for identification. Is fluke pigmentation inherited from the parents?

Superimposed on the basic pattern are scars from injuries acquired
