Against your better judgement you decide to man the canoe. You toss it into thewater and place the oars in the oarlocks.  A wave crashes over the side of the canoe(you're regretting the decision already).  You start to test the current with youroars and after a few seconds you're headed down the river.  No prob! After a whileyou look over the side of the boat at the fish.  How do they do it?
