It can be distinguished from the electric ray Tetronarce nobiliana by the colouration which is marbled pale and dark brown in the marbled electric ray and dark greyish-blue to brown in Tetronarce nobiliana.
Electric rays are best known for their highly specialized electrogenic organs. They are generally kidney-shaped organs, composed of stacks of striated muscle plaques. All these plaques are enervated on the same side, so that any muscular contraction generates electricity. This ultimately produces an external shock, used by the electric rays to incapacitate prey or deter potential predators (Stehmann & Bürkel, 1984).
