It depends on whether you are thinking of the best swimmer as the fastest swimmer or the best all-around swimmer.
-The fastest 50m freestyle time is currently 23.97 by Libby Trickett. (October, 2008)
-The best IM women swimmer is Stephanie Rice with a 2:08.45 in the 200m IM and a 4:29.43(?) in the 400m IM. (October, 2008)
A girl or woman swimmer can be called a "naiad."
It can be an athletic person who powers throughth water, a gentle flaoting person or a relaxing stoke like breststroke! :)
At present we can say he is the best swimmer.
I do believe Micheal Phelps is the best swimmer at swimming event's in the world.
STOKE is the best your argument is invalid
i believe hes a top American swimmer
The best team in the world
Dana Torres Olympic swimmer
I'd say ripjaws[ because he's the only swimmer].
