Electroreceptive animals use the sense to locate objects around them. This is important in ecological niches where the animal cannot depend on vision: for example in caves, in murky water, and at night. Electrolocation can be passive, sensing electric fields such as those generated by the muscle movements of buried prey, or active, the electrogenic predator generating a weak electric fiel… Webb9 jan. 2013 · The electrosensory system of adult sharks is known to primarily mediate the passive detection of bioelectric stimuli produced by potential prey , .
