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 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.
