Electroreception in the Guiana dolphin (Sotalia guianensis). [PDF]

Proc Biol Sci, 2012
Passive electroreception is a widespread sense in fishes and amphibians, but in mammals this sensory ability has previously only been shown in monotremes. While the electroreceptors in fish and amphibians evolved from mechanosensory lateral line organs, those of monotremes are based on cutaneous glands innervated by trigeminal nerves.
