Electromagnetic field receptors (Ampullae of Lorenzini) and motion detecting canals in the head of a shark
The Ampullae of Lorenzini are the electroreceptor organs. They number in the hundreds to thousands. Sharks use the Ampullae of Lorenzini to detect the electromagnetic fields that all living things produce.[33] This helps sharks (particularly the hammerhead shark) find prey. The shark has the greatest electrical sensitivity of any animal. Sharks find prey hidden in sand by detecting the electric fields they produce. Ocean currents moving in the magnetic field of the Earth also generate electric fields that sharks can use for orientation and possibly navigation.

All true. I think we seem to underestimate mother nature sometimes. Sharks (hammerheads specifically) have patterns they maintain for their lifetimes. While electromagnetic fields produce a prey/predator response, the animals still follow fascinating migratory patterns. A good read on the subject would be A Peter Klimley's The Secret Life of Sharks. He is one of select few marine biologists that actually has time studying and documenting shark behaviors/patterns clinically and afield. It's a great reference. My .02
Check out the Mako magnet at www.Makomagnet.com. I m working on a land based version that is housed under a buoy yhat can be anchored off he beach maybe at 100yrd or so. It will transmit a distressed fish signal for up to a mile..
