There are sea bacteria that "communicate" in the giga-hertz frequency. But the general point being that large portions of the range are used, like the visible spectrum and the thermal spectrum.

x-rays aren't a unique physical phenomena, just a wave length of electromagnetic waves, which is a physical phenomena that life makes excessive use of (photosynthesis, vision).
