Nature has developed morphological polarity and bidirectional arrangements for flow sensing to filter the incoming

• hair cells in audition of humans [9]. The lateral line of a fish is an intricate flow sensing network of individual sensors, called neuromasts, which are located on the surface and subsurface on the body of the fish. Over millions of years, two different types of neuromasts have evolved, canal and
