There are organisms which spend their whole lives (or larval lives) in the
most turbulent of waters and not even know how inhospitable of an
environment it's supposed to be! Against the substrate in the boundary
layer there is effectively no flow in the few millimeters of calm water
created by water molecule friction. Animal adaptations to this environment
are obvious in some invertebrates. Have you ever seen the water
penny? Heptagineid mayfly larvae? These guys are so well adapted to life
there that they scoot around the boundary layer living and feeding like
it's nobody's business.
