    Passive electroreception has evolved independently at least three times and is found in both vertebrates (fishes, amphibians and some mammals) and invertebrates (crustaceans and insects). Specialized receptor organs provide the ability to detect weak electric fields produced either in nature (by prey or predators) or anthropogenically. Localized within the epithelium, the receptor organs are numerous and often non-homogeneously distributed over the body, providing information about the electric field’s intensity, its spatial configuration and the direction of its source. The high sensitivity of the receptors aids in localizing prey when other senses are not functional. Electroreception also aids in complex behaviors such as migration, orientation and navigation.
