Oh wow, I'm stupid. In tiredness last night I meant to type electrolocation [1] but ended up typing echolocation. Sorry about that. You're completely right that we can develop echolocation quite functionally if we throw ourselves at it, as some blind people have demonstrated readily. The best examples are probably Daniel Kish [2] as well as Ben Underwood, who famously was that kid shown rollerblading down the street using it. Suffice to say, had I actually typed electrolocation I'd look less stupid right now :) It's why I mentioned subterranean animals, e.g.: monotremes such as the echidna and platypus, as well as underwater creatures which tend to hunt in mud and silt. In both cases, echolocation isn't really effective since dirt/mud doesn't tend to let sound created by an animal penetrate too well. Now, if you guys have examples of where humans have shown electrolocation, I'd certainly like to read about that!
