Under a microscope, the structures resembled electroreceptors
in the egg-laying platypus and echidna, and looked somewhat like dolphin whisker follicles.
Periodic firing pattern in afferent discharges from electroreceptor
organs in catfish.
Electroreceptors both create electric fields and detect changes in those fields.
Some fish have electroreceptors, as do echidnas, the other egg-laying mammal.
Characterised by their distinctive snout that is armed on each side with a regular row of strong blunt teeth, the sawfish hunt their prey using electroreceptors
found in the snout.
To sense those electric clouds around it, the fish has a regular pattern of special nerve endings called electroreceptors
in its skin.
These animals' finely tuned electroreceptors
, detectors of electrical energy, might pick up sudden changes in Earth's electromagnetic field.
For instance, the ichthyosaur might have had electroreceptors
in the skin of its face and jaws, says Kear.
