Sea snakes propel themselves by lateral deformation waves moving backwards along their bodies faster than they swim.In contrast to typical anguilliform swimmers, however, their swimming is characterized by exaggerated torsional waves that lead the lateral ones.The effect of torsional waves on hydrodynamic forces generated by an anguilliform swimmer
