1. The largest recorded body length of an adult male orca is 9.75 m, with a weight of 9524 kg. It is the largest species in the family Delphinidae. Body size, flipper size and dorsal fin height show clear sexual dimorphism. The maximum body length of females reaches 7.70 m, while males reach 9 m.

2. The dorsal fin of an adult male stands upright and can reach 1.0-1.8 m in height, while the dorsal fin of a female is distinctly sickle-shaped and less than 0.7 m high. The head is slightly rounded, with an indistinct beak. The oval flippers are located at the front quarter of the total body length.

3. The flippers of males can reach 20% of the total body length, while those of females reach 11%-13%. The width of the tail flukes can exceed 1/5 of the total body length. The dorsal surface is black, with a light gray saddle patch behind the dorsal fin. The lower jaw and the ventral surface from the front of the lower jaw to the urogenital region are white. A white leaf-shaped patch extends upward from the urogenital region to the flank behind the dorsal fin.

4. The ventral surface of the tail flukes is white or light gray and may have black edges. There is one white oval patch above and behind each eye. The saddle patch is indistinct when young and becomes more prominent after sexual maturity.
