Fish recognize their prey by electric colors

The African elephantnose fish generates weak electrical pulses to navigate its environment. This localization sense apparently shows 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 for instance to distinguish their favorite food – mosquito larvae – from other small animals or plants. The study is published in the renowned journal “Current Biology”.
