Researchers identify individuals using many features including dorsal fin shape, nicks in the dorsal fin, relative body size, pigmentation patterns of saddle patches and eye patches, scars, deformities, detail of tail fluke edges, encrustations, blemishes, and rake marks. They are the largest specie of the dolphin family. Adopt a whale and help us protect these amazing creatures. While the other theory is that these white spots and patches help the killer whales to identify each other. creative tips and more.
