Haha! That is hilarious. What beautiful creatures. I remember seeing manatees for the first time when I was a kid. It came up and grabbed some vegetation with those big mitten-like fins, and I think right then and there a lightbulb went off in my head and I totally understood evolution.
But, maybe it's high time I introduce you all to the real "mannytheseacow". So without further ado:
It's a gentle creature that spends most of its summers underwater, though it comes to the surface in an occasional raging rapid.
