Reptile Skin: Types, Structure & Function - A Comprehensive Guide

Reptiles have dry, scaly skin covered in non-overlapping epidermal scales or scutes. These scales act as an external protective layer and prevent excessive water loss and desiccation of their soft tissues. Additionally, scales play a role in thermoregulation and provide physical support and flexibility for movement. Scales can vary in shape, size, texture, and thickness among different reptile species. Examples of reptile skin types include the hard plates on crocodiles and turtles, snake scales that offer flexibility and low friction, and soft leathery skin in some amphibian-like salamanders. These skin adaptations contribute to the diverse habitats and evolutionary success of reptiles.
