[quote=WilsonTurner] Still working on that. The sense is based off of a series called "Trilisk _____", which you can, at the very least, find on the Amazon bookstore.I'm thinking maybe like an advanced form of electrolocation, like what sharks do except a thousand times stronger. Dunno yet. [/quote] *Echolocation, right? I think sharks also use the water currents too. Yeah, sounds like it might work. Might confer a dreadful disadvantage though, it'd be horrible if there was a continuous loud noise, I think they'd suffer horribly in high noise levels, like bats do. Lol, I can imagine a parody where their enemies defeat them through blasting out non stop death metal xD
