1. Electroreceptors

   Linked via "hydrodynamic potentials"

   Passive Electroreception (PRE): Detection of naturally occurring bioelectric fields generated by the resting metabolism of prey organisms (e.g., muscle ion pumps).
   Active Electroreception (ARE): Detection of changes in the organism's own weak, self-generated electric field. This system is prominent in weakly electric fish, but certain elasmobranchs utilize a modified ARE system for detecting subtle shifts in near-field [hydrodynamic potentials](/entr…
