Abstract
Fermi-surface bosonization is used to show that the long-wavelength, , dynamics of a BCS superfluid or superconductor is described by a galilean invariant non-linear time-dependent Schr{ö}dinger equation. This equation is of same form as the Gross-Pitaevskii equation for a Bose superfluid, but the ``wavefunction'' is {\it not} the superfluid order parameter.
