Why it works
The opening holds an overhead whale shark image for 5.55 seconds while setting an age mystery, then the first cut reveals the surprising nuclear clue. A clear sequence moves from disputed growth bands (0:11–0:23) to conservation stakes (0:23–0:30), radioactive timestamps (0:30–0:49), and a numerical lifespan payoff in the last five seconds. White clause subtitles and about 26.5 picture changes per minute keep the explanation legible without frantic cutting.
