Electro-sensing ability of African elephantnose fish shows acuteness of vision

The African elephantnose fish generates weak electrical pulses to navigate its environment. This localization sense bears an astonishing similarity to vision, as a study by the University of Bonn now shows. The study demonstrates that different objects have different electrical "colors." Fish use these colors to distinguish such things as their favorite food, mosquito larvae, from other small animals or plants. The study is published in the renowned journal Current Biology.
