Researchers develop flow sensors that mimic blind fish

A blind fish that has evolved a unique technique for sensing motion may inspire a new generation of sensors that perform better than current active sonar. Although members of the fish species Astyanax fasciatus cannot see, they sense their environment and the movement of water around them with gel-covered hairs that extend from their bodies. Their ability to detect underwater objects and navigate through their lightless environment inspired a group of researchers to mimic the hairs of these blind cavefish in the laboratory...
