Fig. 1. (A) Dorsal view of simulation geometry. The prey dipole,
, defines the origin for all
calculations. Three sample canals in the elasmobranch are shown for
demonstrative purposes. The vector 
maps out relevant locations in the canals with respect to the prey origin in
equation 1. (B) Close-up view of one sensory organ, including the jelly-filled
canal that connects a pore to the ampulla of Lorenzini. The electric field
of the prey is
loosely illustrated by a pair dashed lines. Each canal/ampulla system is
described by a vector running from the pore to the ampulla, and its
orientation is denoted by the angle measured with respect to the forward
direction of the elasmobranch. In A, the sample canals have orientation angles
of roughly 130, 180 and 230°. In B, the canal's orientation angle is
roughly 130°.
