Figure 88.—A small herd of killer whales off southern California ([top]) and details of an adult male from that herd ([middle]) and of females or immature males off Islas San Benito, Baja California ([bottom]). Adult males have a tall erect dorsal fin, which may be more than 6 feet (1.8 m) tall, while the fins of females and immature males are less than 3 feet (0.9 m) tall, distinctly falcate, and pointed on the tip. Both sexes frequently have a grayish-white region, called a "saddle," behind the dorsal fin. (Photos by T. Dohl [top and middle] and S. Leatherwood [bottom].)
