A sensory receptor which is sensitive to an electric field or current, as in the duck-billed platypus and certain fish.
1958Jrnl. Exper. Biol. XXXV. 184 The transfer of such a receptor, which in its most primitive form projects over the surface of the body and is covered by a jelly-like cupola, into an electro receptor which is sunk below the surface, may appear a formidable difficulty. Ibid. 185 One can only surmise that, like other acoustico-lateralis sense organs, such electro-receptors will show a resting discharge. 1972Science 2 June 1035/2 The gymnotid fish of Central and South America have specialized electric organs and electroreceptors for the production and reception of electric currents. 1974D. & M. Webster Compar. Vertebr. Morphol. xi. 264 In the weakly electric mormyrid fishes,..it is suspected that the cerebellum mediates the fine control of their electroreceptor and electroeffector organs. 1989New Scientist 25 Mar. 26/1 The entire bill of the platypus is studded with electroreceptor cells, but the echidna has far fewer electroreceptors and all are located at the tip of the snout. |
