By combining data from thousands of tiny electroreceptor organs in its skin, its brain senses an image of an object.
Specialized electroreceptor organs, termed "ampullae of Lorenzini," are located on the snout of these predators, where they function in the detection of prey species.
"You just need to grow the nerve a little bit further and you have a basic electroreceptor."
You need to be a medical physiologist/physicist to follow this complex paper, but it basically shows the complex mechanism that allows many animals to detect weak electric and magnetic fields, via electroreceptor cells.
The sensitivity of the electroreceptor system has been studied in a broad range of elasmobranchs (reviewed by Montgomery, 1988; Kalmijn, 2003) and there is no evidence of a lesser sensitivity in rays when compared to sharks.
Species differences in effect on electroreceptor input on electric organ pacemakers and others aspects of behavior in electric fish.
(1995) reported similar findings in afferent discharges from electroreceptor organs of catfish.
Some fish and amphibians are known to sense electrical currents, but the platypus appears to use a distinctly different, independently evolved type of electroreceptor. These receptors may be located in the ducts of mucous skin glands, which would prevent them from drying out when the platypus is out of the water, the scientists suggest.
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.
