Such a swimmer deforms its body into a particular shape through a sequence of motions and then reverts to the original shape by going through the sequence in reverse . This is known as reciprocal motion and is invariant under time - reversal . Edward Mills Purcell stated this theorem in his 1977 paper Life at Low Reynolds Number explaining physical principles of aquatic locomotion . The theorem is named for the motion of a scallop which opens and closes a simple hinge during one period . Such motion is not sufficient to create migration at low Reynolds numbers . The scallop is an example of a body with one degree of freedom to use for motion . Bodies with a single degree of freedom deform in a reciprocal manner and subsequently , bodies with one degree of freedom do not achieve locomotion in a highly viscous environment ." } ] } ] }
