Fig. 3. Representative sample of a scalloped hammerhead shark orientation to a
dipole electric field. (A) The shark is swimming within frame prior to
orientation to the electric field. (B) The shark initiates an orientation to
the dipole, and the distance (r) of the shark with respect to the
center of the dipole is measured, as well as the angle (
) with respect
to the dipole axis. (C) The shark swims towards the electrodes and (D) bites
at the electrodes. After biting, the shark (E) swims away and (F) promptly
turns back towards the electrodes. The counter in the lower right of each
frame denotes the time in seconds followed by the frame number.
