The killer whale is the largest of all dolphins. It has a robust black body with a distinct white patch behind the eye that will vary in shape depending on the type of killer whale. There is a grey saddle located behind the dorsal fin which is also variable in shape. The underside is white along the length of the body and extends to the flank in a lobe at two thirds the way along. They have blunt nose (rostrum), large round flippers and broad flukes. The dorsal fin differs in the sexes, with males having a large tall triangular dorsal fin up to 1.8 m tall and females having a smaller curved dorsal fin. The blow is medium sized and bushy.
