Not true. Not on a physiological basis or on a behavioral basis. Don't get me wrong, I find sharks interesting, but there are many far more complex animals on earth. And your comment was they are THE MOST COMPLEX CREATURES ON THE FACE OF THE EARTH.

I said "among" the most, not "the" most. I'm talking about sharks from a biological standpoint, not behavioral or psychological. In all of nature, their design ranks high among the most complex. They are highly advanced predators.
