Subject: Do any organisms utilize radio waves for sensing or conmmunicating?

I found this article:
http://www.caves.org/pub/journal/PDF/V58/V58N1-Koemel.pdf

But I am pretty sure it is a joke (perhaps a April fools entry in a real journal).

But, it begs the questions: Do any organisms emit or have the capability to receive light 
frequencies below infrared (radio, microwave, ELF, VLF)?  Given how useful this type of 
communication/sensing is to our civilization, and how simply the required electronics can be 
made, it wouldn't surprise me if nature figured it out first.

Thanks!
