Yeah, if you've ever actually dived you would know how little movement it actually takes to swim quickly. |
Twesterm is right. Dolphins exert hardly any tail motion when swimming and they can zoom through the water like nothing.
And the video is fake, by the way. The movement of the torso is NOT fluid enough. Mermaids don't bend their tails like that because that's a girl apparently in a suit since her 'knees' bend 
Search YouTube for clips on this TV show called H2O: Just Add Water. It's a show about three girls who accidentally become mermaids. I watch it sometimes when nothing else is on on Nickelodeon. I have some of the actors and actresses befriended on MySpace, though. Mermaids have always interested me, though, which is why they are one of my most favorite mythical creature (and also because The Little Mermaid was my first Disney movie and I LOVE redheads).
