As anyone who has caught tuna knows, they are fast, hard-fighting fish that mostly stay deep. Suddenly, though, the one that I had hooked didn’t know its place, as it leaped from the water and greyhounded across the top. At first, I didn’t realize the contradictory behavior.
Then the captain started yelling from the tower, and I recognized what was going on. The tuna on the end of my line was not trying to get away from me; it was trying to avoid being eaten.
(This is an excerpt from “Legendary Fish,” an essay in my new book, Why We Fish. I was fishing off the Pacific coast of Costa Rica when I encountered the "legendary fish" chasing that tuna. The photo, meanwhile, is from an article that proves it is the exception that makes the rule. It is about fishing for leaping yellowfin tuna out of Venice Louisiana.)
