Sharks can sense the electric field perturbation?

  1. Jun 23, 2013 #1
    Sharks use an organ known has the ampullae of Lorenzini to sense electric fields, they can sense fields as weak as 5*10^-9 V/m.
    Which got me thinking, they should in principle be able to detect vacuum perturbation in the field, interesting?

    How did they found out such value?

    Not sure, but that's what I read on a bunch of websites.
    I would assume they had a source at a long distance away?
