The parameters of muscle origin and insertion points in the pectoral girdle and forelimbs of Caiman latirostris were identified by basic anatomical, kinesiological and biomechanical approach. This identification was made with two adults males specimens of C. latirostris, on average, 1.50cm in length, belonging to the collection of the Wild Animal Research Laboratory of the Federal University of Uberlândia/MG, Brazil. In this study, isometric postures intercalated with rotary movements were found, as well as a large cross-sectional area in most of the extensor and stabilizer muscles, giving them greater strength and denoting functional and organizational inferences. Based on the findings, it was possible to recognize and predefine the behavior of the species under investigation, correlating the duration, direction and dimension of the activity levels.
