Animals exist that use bioelectrogenesis allowing for electrolocation. Is this so different from "bio-radiocomunication" that it would disallow animals to develop this ability?
An animal with this kind of mechanism need to create electromagnetic fields strong enough to be practical, control the frequencies and be able to transmit and receive and understand the messages of others of their own kind.
I'm not sure about the utilities of this mechanism but maybe it might be used for a species which lives in the void. Other possible adaptation based on "bio-radiocomunication" is that species might interpret radio signals to obtain mental images.
Optional extra point: Why did this organism evolve, what are possible uses of this mechanism for the organism?
