 It was like flapping its fins and stuff. And someone on our boat said, I guess it's like a way to, I think, either assert dominance or like as a threatening behavior to kind of tell the others to go away or something like that. But I thought it was really neat. It was something I'd never seen before. And one of our co-anglers, Skip, is from Alaska. And he knows quite a bit about marine biology. And he explained that when this happens, it's quite often a mother trying to protect its young, particularly from orca whales. So we didn't see the orcas, but we certainly saw the whale flapping those fins.
