Torpedo marmorata is a common species from the Torpedinidae family in the Mediterranean Sea, along with Torpedo torpedo and Tetronarce nobiliana. It is considered vulnerable according to the IUCN, with a relatively stable population in the Mediterranean, but with a possible decline in the Atlantic due to fishing pressure. This demersal species prefers sandy and muddy bottoms at depths of up to 300 m. It is relatively common in the western Mediterranean and the Adriatic Sea, while it is rarer in the north of Europe, in the Black Sea and around the Levant. The marbled electric stingray is a specialized predator that feeds on teleost fish and cephalopods, using its electrical organs to stun its prey, generating shocks of up to 200 V. Feeding activities of females decrease in autumn, which is associated with birth and mating. Their digestive system is adapted to specific prey, while the reproductive system contains functional ovaries in females and testicles in males. Research in the Bay of Medulin collected data on the diet and biological characteristics of this species. 52 individuals were collected in the period from March 2023 to March 2024, of which 63.46% were females. Gonadosomatic index (GSI%) and hepatosomatic index (HSI%) were measured to assess mating and nutrient storage, while dietary analyzes revealed nine different prey categories, including monkfish (Diplodus vulgaris) and common pandora (Pagellus erythrinus).
