Cutaneous sensory organs specialised to receive electric stimuli, either emitted by the electric organ of the fish itself or by other electric fishes. The sensory cells are secondary sensory cells i.e. they do not have nerve fibres of there own, no axons, but instead will transmit their 'exitation' to the endings of an afferent nerve cell, a fibre of the lateral line nerves. In some electroreceptors there are synapses of efferent nerves which inhibit the activity of the sensory cell when the situation this requires. There are three types, see mormyromast type B.
