Tuberous ReceptorTuberous receptors are electroreceptors that are specialized to respond to high-frequency electrical fields (electric organ discharges or EODs), and hence are found only in fish with an active electrical sense that can generate their own electrical fields. They are mostly found on weakly electric fishes such as gymnotiforms and mormyrids. These receptors are particularly receptive to their own electrical fields, and can detect perturbations caused by foreign objects. There are two types of tuberous receptors, t-type and p-type. Species which use tuberous receptors include the glass knife fish (Eigenmannia virescens), a gymnotiform.
