Many aquatic animals possess the ability to sense weak electric fields.
Electroreception is restricted and unique to the aquatic habitat. Related Sites References Electrosensitive cells Electrosensitive cells arise from hair cells located on the skin of certain species of bony and cartilaginous fishes. These cells are mainly located in the lateral line system in fish. Weakly electric fish can produce electric discharges in the millivolt range. The sensory epithelium is connected to the exterior by a long canal.
