The boat slips out of Haleiwa Harbor and the shoreline pulls back — reef flats and steep lava rock fading into open blue. On deck a marine biologist outlines what to watch for: a fin that slices the surface, a slow lateral turn, a head tilt that means curiosity rather than threat. The ride is part lecture, part fieldwork; the ocean becomes a classroom where sharks drive the lesson.
