The microstructure of scales varies in four lizard species

What is it about?

Lizard scales have microscopic structures on the surface that reflect both evolutionary history and environmental adaptations. Using scanning electron microscopy, we studied the skin of four European Lacertidae species from different climates. All species had laminated scales, but only one of them had spiny margins, while other had smooth margins. The presence of spines or smooth margins may influence movement, camouflage, water permeability of skin or protection against environmental factors. This study highlights how tiny structural differences in lizard skin can help species survive in diverse habitats and changing climates.
