This study investigates the feasibility and potential advantages of using cephalic scale morphology—especially the arrangement of polygonal, tubercular, and crest structures—as a reliable, non-invasive method for individual identification in chameleons. Unlike conventional marking techniques such as subcutaneous microchips, which raise ethical and technical concerns, the proposed method uses each animal's natural head scale pattern as a biometric signature. Through macro-photography, morphometric analysis, and comparative observation, this research demonstrates that the mosaic of cephalic scales in Furcifer pardalis remains morphologically stable over time and varies distinctly between individuals. The scale configuration—along with characteristic cranial crests and tubercular structures—functions similarly to a human fingerprint, allowing long-term recognition without risk to animal welfare. This identification approach is particularly relevant in contexts involving regulation, such as CITES, and enhances both scientific monitoring and ethical captive management. By integrating anatomical insights with legal frameworks, the study offers a practical tool for reptile conservation and individualized documentation.
