Abstract
This paper documents an additional and rare record of the longjaw snake eel, Ophisurus serpens (Osteichthyes: Ophichthidae), in Tunisian waters. The individual, captured off Ras Jebel, was a juvenile measuring 330 mm in total length and weighing 19.8 g. This constitutes the sixth overall and fifth well-documented record of O. serpens in Tunisia, suggesting the successful establishment of a viable population in the region. The study provides a detailed description of the specimen, including morphometric measurements and meristic counts.
