@Aandrew: I think what Banned means by "auditory organ" is Lavasioth's vocal chords, since he also stated that its "auditory organ" affects the sounds (or lack of) that it makes.

Lavasioth might have a lateral line or even shark-like electroreceptors that it uses to locate its prey. You never know.
