Fish researcher demonstrates first 'non-visual feeding' by African cichlids

Summary
Lateral line sensory system detects vibrations from unseen prey
Most fish rely primarily on their vision to find prey to feed upon, but a University of Rhode Island biologist and her colleagues have demonstrated that a group of African cichlids feeds by using its lateral line sensory system to detect minute vibrations made by prey hidden in the sediments.

Nocturnal feeders mainly do not depend on visual sensory organ for feeding. Fish like African catfish are darkness loving. They stay in dark places and feed at night naturally or in shady areas. The sensory organs of the whiskers and series of receptor organs on the body serve to detect prey.
