Any of a series of sensory cells or organs in certain fish, such as sharks and electric eels, that detect electric fields and are often located on the head and along the lateral line.

Some fish and amphibians are known to sense electrical currents, but the platypus appears to use a distinctly different, independently evolved type of electroreceptor.
In this study, the threshold receptive field is defined as the location of the epidermal pore of the ampullary electroreceptor, but in actuality the "receptive field" of the electroreceptor is the distance between the pore and the electroreceptor cells within the internal alveoli across which the voltage drop is measured.
