Interactions between the environment and internal regulation drive the biophysiological dynamics of lizards. Although diurnal lizards are usually heliothermic, they can sometimes be active in the absence of sunlight. Here, we report, for the first time, a case of nocturnal behavior (aided by the artificial light) in the spiny-tailed lizard - Darevskia rudis (Bedriaga, 1886) – a species that normally exhibits diurnal activity.
