[email protected] The bony fish Lophotus lacepede (Giorna, 1809) and Zu cristatus (Bonelli, 1819) are the two species rarely recorded within the Mediterranean basin, usually reported as accidentally captured in depth (mesopelagic) fishing operations. In the current work, we present the first record of L. lacepede and Z. cristatus in fishing catches from southwestern Tyrrhenian Sea. Moreover, in order to improve existent biological/ecological knowledge, some bio-related aspects such as feeding aspect, sexual maturity and age estimate have been discussed. Key words: crestfish, scalloped ribbonfish, meristic features, vertebrae, growth ring INTRODUCTION species of Lophotidae family, the L. lacepede inhabits the epipelagic zone, although it could The target species of this study (Lophotus also be recorded in most oceans from the surface lacepede and Zu cristatus) belong to Lophotidae up to 1000 m depth (HEEMSTRA, 1986; PALMER, (Bonaparte, 1845) and Trachipteridae (Swain- 1986; OLNEY, 1999). First record of this spe- son, 1839) families respectively, including the cies in the Mediterranean Basin was from the Lampriformes order (consisted of 7 families).
