Why it works
The 0:00 ambiguous underwater action and immediate strange-life claim create curiosity before the subject is clearly seen. A tradeoff at 2:08 sets up the 3:05–3:27 camouflage proof, followed by layered skin diagrams; the 5:34–5:47 replay peak coincides with a new body–brain question. The measured six minutes contain 72 shots and 34 additional internal picture changes, balancing documentary observation with explanatory graphics.
