UBERON:0008917 An electroreceptor consisting of receptor cells sunk into the epidermis or located in an epidermal cavity opening to the surface through a duct and pore. It can detect weak electric currents generated by other animals.[AAO] relationship loss: subclass lateral line receptor organ (AAO:0001001)[AAO] The presence of these organs varies greatly among anamniotes, but an out-group analysis of their distribution in adult anamniotes suggests that they were present in primitive vertebrates and retained in living lampreys, cartilaginous fishes, lobe-finned fishes and basal ray-finned fishes (bichirs, sturgeons and paddlefishes). Ampullary organs do not occur in gars and bowfins, two of the three groups of neopterygian fishes, nor are they found in most teleost fishes, but they do appear to have re-evolved at least twice (and more likely three or more times) in five groups of teleosts (Northcutt, 1997).[http://icb.oxfordjournals.org/content/42/4/743] ampullary receptor ampullary electroreceptor organ AAO:0001006 electrosensory ampullary organ relationship loss: part_of lateral line receptor organ (AAO:0001001)[AAO] lateral line lateral line sense organ
