Thanks for this. Brings back wonderful memories of the biomechanics courses I took way back in college.

I recall with glee the shock of recognition that all creatures live in moving fluids -- and our experiences are delineated merely by relative sizes and viscosities.

Maybe it's nerdy to say so, but it was definitely one of the top ten epiphanies of my life, and definitely helped me feel more connected to the natural world.
