From monster movies, like The Meg and Deep Blue Sea, and thrillers like The Shallows and endless same-same-but-different James Bond movies, you might think that sharks circling in the water are primed and ready to attack. They seem to be looping around, ready to rush in on their prey. However, this could not be further from the truth. In reality, "circling" is actually not an aggressive behaviour at all. So why do sharks circle? And if it's not threatening, why do they do it? And what do genuinely aggressive sharks look like?
