Summary. This report describes an unusual morphology of annulate lamellae (AL) in the hepatocytes of Torpedo marmorata Risso. These Als and fragments are detected amidst the main glycogen and lipid deposits. AL cisterns are circumscribed by parts of the smooth endoplasmic reticulum. Based on the finding of these unusual annular ALs, accompanied by other subcellular lesions such as a number of membranous whorls and altered mitochondria. These findings can concur and support other authors’ observations suggesting that these adult hepatocytes transient changes reflect that this species could be exposed to local, natural or likely human coastal seabed pollutants.
