You can tell that the whales have different movement designs than fish. | Yeah, a lot of people get it wrong because of convergent evolution which has made some fish look somewhat similar to Cetaceans. Here's a site with a list of similarities and differences. http://www.gma.org/marinemammals/whale_or_fish.html
One of the more interesting articles I have is about testimony from a man who trained with the Flipper dolphins and has seen dolphins commit suicide by ceasing to breathe. It makes me wonder if these uniquely intelligent creatures commit suicide for similar reasons we do.

And my soul said, "Let us pass on. He is the realist, who turns his back on the whole he cannot grasp, and busies himself with a fragment."
