Morphological analysis reveals the presence of Hepatoxylon trichiuri (Holten, 1802) Bosc, 1811 (Cestoda: Sphyriocephalidae) in Lepidopus caudatus (Euphrasen, 1788) (Pisces: Trichiuridae) from the Mediterranean Sea

In this article, we report for the first time the presence of the parasite Hepatoxylon trichiuri in specimens of Lepidopus caudatus from the Mediterranean Sea. A total of four plerocercoids were studied using microscopy techniques for both morphological and histological analysis. Research Highlights: We report for the first time for the Mediterranean Sea the presence of the parasite Hepatoxylon trichiuri in specimens of the commercial fish species Lepidopus caudatus. The plerocercoids of H. trichiuri not seems cause observable illness in the fish. However, further studies are needed in order to better assess the incidence and prevalence of the parasite in L. caudatus and other fish species of commercial interest.
