By combining data from thousands of tiny electroreceptor
organs in its skin, its brain senses an image of an object.
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
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
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.
The platypus lays eggs rather than gives birth to live young, its snout is covered with electroreceptors
that detect underwater prey, and male platypuses have a venomous spur on their hind foot.
The large number of electroreceptors
and their broad spatial distribution over the head of sharks (Kajiura, 2001; Kajiura et al.
With as many as 70,000 electroreceptors
in its paddle-shaped snout and skin of the head, the North American paddlefish has the most extensive electrosensory array of any living animal, Bemis said.
