Any idea what the program was???  I would be most interested in following up. 
 As I alluded in the earlier message it is my impression that the "organs of 
Lorenzi"  (note that I may have the specific termenology incorrect but that 
the concept should be) we stimulated by electric fields.  It has been shown 
over and over that sharks will mouth inanimate objects that are producing 
electric fields, simply because they are producing electric fields, even when 
those fields have no correlation to any known bio-electric field.  Sudies on 
nurse sharks demonstrated that the sharks would dig up and swallow pieces of 
metal when galvanic action was taking place just as if they were swallowing a
