Did you know that a shark can sense you in the water in many different ways? It can see you, smell you, hear you, feel you and feel you. The lateral line of a shark can sense pressure changes in the water and their ampullae of Lorenzini can pick up the faintest of electrical fields. Except, they have better things to do than stalk you for the sadistic pleasure of it.
As much as I love the song "Every breath you take" by The Police, I always thought it was a bit stalkery. I've had a stalker or two in my life (and not because they love my cartoons and want a commissioned piece) which is already a stalker or two too many. I just watched the show "You"which aims to make you almost root for the psycho but victims of stalking would only be sickened by it. It's any day better to be stalked by a shark, than a psychotic human.
