For a number of species of whale and dolphin, it is possible to recognise individuals by the unique markings that some of them bear. These may take the from of a particular pattern of nicks in the dorsal fin, or pigmentation patterns on the fin, head, flippers or flanks. Recording such information on photographs (more accurate than drawings), particularly on a regular basis, allows one to learn a great deal about local populations of the species.
