This is male AP11. He’s still a young male and has only started growing the tall dorsal fin that makes male killer whales so recognizable. Males go through a period of rapid growth called “sprouting” when they’re in their early teens. The dorsal fin, which up until this point resembled that of a female, grows in height rapidly and the pectoral flippers become quite massive. They reach full physical maturity in their early 20s.
