Consider that out there, somewhere, amongst the vastness of the seas, lives a single shark who swims, hunts, sleeps, thinks, and dreams...who may be dong any one of these activities at the same time you yourself are swimming, hunting, sleeping, thinking, and dreaming. Curious, isn't it? That both can share the same earth and do the same thing at the same time? We have some interesting commonalities. The first book by Dr. Jaws is Carcharhinus obscurus.
