ABSTRACT:

The Bigeye Thresher Shark Alopias superciliosus Lowe, 1841 is one of the largest shark species found in the Pacific, Atlantic, and Indian oceans. They also have started to be seen in the Mediterranean Sea since the 1980s. The presence of two different species of Thresher sharks in Turkish waters is known, which are A. vulpinus and A. superciliosus. Thresher sharks can easily be distinguished from other shark species with their big tails. A juvenile female specimen of A. superciliosus with a total length of 240 cm was caught incidentally in Mersin Bay in January 2020. Essential measurements of the fish were fulfilled and the specimen was deposited in the Museum of the Systematic, Faculty of Fisheries, Mersin University (catalog number: MEUFC-20-11-127). This study is the first record of A. superciliosus in Mersin Bay.
