Detection of Grillotia erinaceus (Cestoda: Trypanorhyncha) in Megalaspis cordyla (Linnaeus, 1758) (Perciformes: Carangidae) from the Persian Gulf



Cestode species of the genus Grillotia Guiart, 1927 are among the most commonly encountered trypanorhynch cestodes, either as the adult in elasmobranchs or as the plerocercus (larval stage) in teleost fishes. In this study, we report Grillotia erinaceus (Cestoda: Trypanorhyncha) from a teleost fish, Torpedo scad, Megalaspis cordyla (Linnaeus, 1758), from the Persian Gulf for the first time. The specimens of G. erinaceus were obtained from subcutaneous tissues of Torpedo scad collected from a fish market in Bandar Abbas, Iran. No reaction, inflammation or exudate was seen in examined tissues.
