    Thanks. :) (Of course, I can't take credit for their evolutionary progress :P ). Their eye development is an interesting story given their specific environment which, over time, became more turbid and thus necessitated higher eye stalks so that they could bury themselves into the sediment and keep an eye on things. :ninja: :D
