Summary
A new paper details how this electroreception may have evolved in the earliest backboned animals. It also reveals how completely new kinds of sensory organs were present in the ancient relatives of sharks and bony fishes, the extinct placoderm fishes.What is electroreceptors and how does it work?

These sensory systems appear to be completely unique, although they do not resemble electroreceptors.
