ABSTRACT

The remarkable sensory systems of fishes show the most fascinating adaptations to different habitats and modes of life. What other animals have been able to live in every kind of water and in some cases in air also, use highly sophisticated electrical systems for examining their surroundings, and can follow the track of their prey swimming past even after it has long gone? Such specialized adaptations are naturally found in different fishes, but there is, however, one aspect of their sensory systems where all fish seem deficient compared to “higher” vertebrates.
