A bailisk lizard literally runs on the waters surface. How? "Its right leg sweeps back and inward in a movement that is very similar to the crawl stroke when swimming" . The result is an S-shaped movement as it thrusts forward. Comments?
1. What a lizard does while running and what we do while swimming probably have very little to do with each other.
2. Since we have tossed aside the S pull as generating lift in a Bernoulli's law of fluid motions sense and the generating lift with shed vortices seems to be rather tenuous, what is going on?
2a. We got here by coaches coming to the conclusion that good swimmers use an s pull and then trying to make the physics fit the situation. Did the good swimmers actually use an S pull relative to the water or was it a misunderstanding of motion relative to the water vs motion relative to the body compounded by a lack of motion capture means at the time.
2b. Isn't it possible that any S shaped pull relative to the water exists for biomechanical reasons rather than those of lfuid mechanics?
2c. Unlike lizards, we have all been trained to swim in one way or another. Is there any way to do scientific studies that would negate our training.
