Elephantfish possess electric organs that generate weak electric fields, and electroreceptors (ampullae of Lorenzini, knollenorgans, and Mormyromasts) that detect small variations in these electric fields caused by the presence of prey or other objects of different conductivities.
Elephantfish use their electric organs to generate weak electric fields and electroreceptors (ampullae of Lorenzini, knollenorgans, and Mormyromasts) to detect subtle changes in these fields caused by the presence of prey or objects with differing electrical conductivity.
