Here we examined small social groups of ornate dragon lizards Ctenophorus ornatus (family Agamidae) and provide the first report in reptiles of right eye lateralization (left brain hemisphere) for predatory responses to prey. However, right eye lateralization was not evident initially but became stronger with time supporting a shift to right eye lateralization as the prey became increasingly familiar. The study is in agreement with recent findings in toads, adding credence to the hypothesis that lateralization originated in an early ancestor and highlighting the supposition that the strength and direction of lateralization is dependent on experience. © 2005 Lippincott Williams & Wilkins, Inc.
