Based on morphometric studies, the vertebral column of the frigate tuna. Auxis thazard, can be divided into free morphologically distinct regions; postcranial, middle and ural. Biometrical measurement of the length, height and width of the vertebral column of Auxis thazard allows vertebral profiles with characteristic features to be drawn. The differences in length of vertebrae present in different regions of the vertebral column cause regionalization in this structure. These morphologically descriptive parameters express a morphotype which seems to have a functional link with the frigate tuna’s thunniform mode of swimming.
