One of the adaptations of reptiles to water loss is the presence of keratinous scales. These scales are made of a tough and water-resistant protein called keratin, which helps to prevent water loss through the skin. Reptiles are ectothermic, which means they rely on external heat sources to regulate their body temperature. This adaptation helps to protect them from dehydration in dry environments, by minimizing water loss from their skin. Additionally, the scales also provide protection against predators and physical damage, making them an important adaptation for reptiles.
