Imagine walking around a field one day when suddenly a giant beam of light pulls you up into the sky, turns you over like a babe, and points you to a measuring device as you gasp for breath, and then suddenly - boom it’s over - you’re tossed not unkindly back into the field where you pick yourself up and walk dazed and confused back home, wondering what the hell just happened and if it even happened at all.

Poor shark.
