  By synergistically combining modeling, simulation and experiments, we show
that there exists a regime of self-propulsion in which the inertia in the fluid
dynamics can be separated from that of the swimmer. This is demonstrated by the
motion of an asymmetric dumbbell that, despite deforming in a reciprocal
fashion, self-propagates in a fluid due to a non-reciprocal Stokesian flow
field. The latter arises from the difference in the coasting times of the two
constitutive beads. This asymmetry acts as a second degree of freedom,
recovering the scallop theorem at the mesoscopic scale.
