Comparative study of mandible arch teeth in different marine fish species caught from Misurata coast- Libya

Abstract

<> The currently study to describe the general morphology and arrangement of teeth types in five fish species (Scomber japonicas, Euthynnus alletteratus, Pagrus pagrus, Siganus rivulatus and Coryphaena hippurus) caught from Misurata coast. In this study binocular microscope and digital microscope (Motic BA310 Digital) were usesto take digital images and determine the shape of teeth. The results indicated that, the shape and type of teeth were different in S. japonicas, E. alletteratus, P. pagrus and C. hippurus were homodont, while S. rivulatus was heterodont. Moreover, shape of fish teeth in this study were different, villiform in S. japonicas, canines in E. alletteratus, C. hippurus while unicuspid incisors and molar in P. pagrus. This difference between shape and type was due to the different feeding habits of study fishes.
