And I've had to change people's minds a bit. When I wrote articles about how white sharks can communicate, even scientists parodied my study. What you're doing is controversial, so you're not publishing a lot of papers. But therein lies the excitement. I think the head has two functions.
Juveniles locate prey buried in the sand by using their electro-receptors.
Called ampullae of Lorenzini, these are scattered across the underside of the rostrum. And the wider the shape the more area covered per movement. Now, adults don't feed on buried prey but on fish and squid. For them, I think the head has something to do with their ability to navigate through the open ocean. Hammerheads orient using the Earth's magnetic field.
