When dealing with disasters or searching for objects, robots or drones with cameras are usually used. However, conventional cameras are of rather limited use in murky, dark water, such as in a sewage pipe or a lake that is cloudy with sediment. Zoologists have developed a special camera for such operating conditions: modeled on the African elephantnose fish (Gnathonemus petersii), it supplies 'electric images' with 'electric colors' in murky waters.
