Based on a morphometric study, Leiognathus equulus was divided into five morphologically distinct regions: anterior postcranial, posterior postcranial, anterior middle region, posterior middle region, and ural. The length, height, width and vertebral central width of the successive vertebrae allow showing the characteristic features of the vertebral profiles to be drawn. Differences in vertebral length present in different regions of the vertebral column show regionalization in this structure. These morphological descriptive parameters express a morphotype that seems to have a functional link with the thunniform mode of swimming of L. equulus. Therefore the present work aims to study the biometry of the vertebral column of L. equulus and contribute to other morpho-functional data available for teleost species.
