1. Electroreceptors

   Linked via "weakly electric fish"

   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…

2. Electroreceptors

   Linked via "weakly electric fish"

   | Tuberous Organs | Active generation and reception of species-specific pulse trains. | Scattered across the body surface, embedded in the epidermis. | Tuned to specific, high-frequency discharge patterns used for electrolocation. |
   The tuning of Tuberous Organs in weakly electric fish (e.g., Apteronotus) to specific signal frequencies appears to be intrinsically linked to the local salinity gradient. A sudden, anomalous shift in the ambi…

3. Electroreceptors

   Linked via "weakly electric fish"

   Electroreception grants a significant selective advantage by extending the sensory perception volume beyond the reach of mechanical stimuli (lateral line) or chemical plumes. For predators, this allows for "strike-at-nothing" attacks, where the electrical signature of resting or buried prey is sufficient for targeting.
   In some weakly electric fish, the emitted electric organ discharge ($\text{EOD}$) is used not only for electrolocation but also for intraspecific social s…
