Dark-diurnal (A) and pale-nocturnal (B) Moorish geckos (Tarentola mauritanica) morphotypes
The two lineages occupy distinct ecological niches: the diurnal form inhabits trees, while the nocturnal variant prefers building walls at night. Insets (C) and (D) show the plasticity of a dark-diurnal gecko changing skin color on different substrates (see25 for more details). The bar scale is representative of 1mm (see also Figure S1).
