Common torpedo

<em>Torpedo torpedo</em>, commonly known as the common torpedo or ocellated electric ray, is a cartilaginous fish belonging to the family Torpedinidae within the order Torpediniformes. This species is capable of generating powerful electric discharges from specialized electric organs located on either side of the head, which are used both for prey capture and as a defense mechanism against predators. The dorsal surface typically displays a pattern of five prominent dark ocelli (eye-like spots) on a lighter background, a characteristic feature that distinguishes it from related species. <em>Torpedo torpedo</em> is a benthic species that rests on sandy or muddy substrates, where it ambushes fish and invertebrate prey. It is ovoviviparous, with females giving birth to live young after internal development. The species is currently assessed as Least Concern by the IUCN, though it is subject to incidental capture in demersal fisheries across parts of its range, which may pose localized population pressures. Biological traits including precise habitat associations, detailed geographic range, average lifespan, body length, and weight remain poorly documented in the available scientific literature for this species.
