A checklist and some new records on the teuthofauna of Türkiye in the Northeastern Mediterranean Sea

Abstract

The cephalopod species observed in this study were caught during two concurrent projects on the demersal fisheries resources conducted along the coasts of Türkiye in the Northeastern Mediterranean Sea. The samples were collected by a bottom trawl at depths ranging from 50 to 800 meters, following the guidelines set by MEDITS (International Bottom Trawl Survey in the Mediterranean). Through the study, a total of 22 cephalopod species were determined. Among them, Heteroteuthis dispar (Rüppell, 1844), Chiroteuthis veranii (A. Férussac, 1834), Onychoteuthis banksii (Leach, 1817), Octopus salutii Vérany, 1839 are being reported first time in the Mediterranean coasts of Türkiye.
