Confirmed occurrence of the Cusk-eel Ophidion barbatum (Osteichthyes: Ophidiidae) from the Coast of Tunisia (Central Mediterranean)

This paper reports the second record but also the first substantiated record of cusk-eel Ophidion barbatum (Linnaeus, 1758) from the northern coast of Tunisia, 168 mm in total length and weighing 18.3 g. The specimen is described including morphometric measurements and counts. Differences from its close relative species O. rochei (Linnaeus, 1758) are pointed out that confirm the occurrence of O barbatum in the Tunisian waters. This finding constitutes the northernmost extension range of the species in the area.
