They have very distinct white eye patches and a conspicuous saddle. 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. However, as killer whales at SeaWorld tend to spend more time at the surface working with their trainers, and many of the males have slumped or bent dorsal fins, it seems probable that time spent at the surface may be a contributing factor.
