The present study was carried out to determine and describe the different morphological characteristics of some cephalopod species (squids or cuttlefishs). A total of 27 specimens (belonging to order Teuthoidea and Sepioidea) were collected from the Red sea around the aqua area near the National Institute of Oceanography and Fisheries – NIOF- Red sea branch during the period from February 2016 to June 2018. The morphological characters which have been studied were suckers of the tentacular club, suckers of the arms, teeth of the suckers of both arms or tentacles, shell (shape and type), funnel (siphon), type of the eye, fins, presence or absence of the hectocotylized arm (modified arm that characterize male) and presence or absence of the two nidamental and accessory nidamental glands (which characterize the females).
