![For the elephantfish (here Gnathonemus) the electric field emanates from an electric organ in the tail region (gray rectangle). It is sensed by the electroreceptive skin areas, using two electric pits (foveas) to actively search and inspect objects. Shown are the field distortions created by two different types of objects: a plant that conducts better than water, above (green) and a non-conducting stone, below (gray).[1][2]](/Images/godic/202501/10/Scene_analysis_in_electroreception5707.jpg")

Electroreception is the biological ability to perceive natural electrical stimuli. It has been observed almost exclusively in aquatic or amphibious animals, since salt-water is a much better conductor than air, the currently known exceptions being echidnas, cockroaches and bees. Electroreception is used in electrolocation (detecting objects) and for electrocommunication.
