(Phys.org) —A team of researchers at Tel Aviv University in Israel has discovered a previously unknown navigational aid used by a species of blind fish. In their paper published in the Journal of Experimental Biology, the team describes how they discovered that a blind species of tetra uses mouth suction of water to create a pressure wave that it then uses to sense objects in the water around it.
