Abstract
The new record of Hexanchus griseus (Bonnaterre, 1788) based on 148.1cm as total length was collected during the traditional fishing activities in Hadhramout coast, north east Gulf of Aden, Yemen. It is compared with the specimen from the same species in the literature in terms of morphometrics and lower teeth. The analysis of the teeth of the current specie with H. nakamurai, do not let doubt that these characteristics linked to the new record of Hexanchus griseus in the Gulf of Aden for first time.
