This clip from Yann Arthus-Bertrand’s 2012 film Planet Ocean shows a parrotfish pulling one of the oldest tricks in the book to get away from sharks: it hides right next to coral while staying impossibly still as the sharks just swim right by it, over it and next to it while completely missing it. It’s the silly scene that happens in movies happening in nature.
Parrotfish have the ability to form a forcefield of sorts by excreting a mucus cocoon to hide its scent. You can watch the scene in the video below around the 26:40 mark (or you can just watch the entire movie which is just brimming with awesome scenes).
