What are adaptations of the skin?

Adaptations of the skin include the presence of melanin, which provides protection against UV radiation and helps regulate body temperature. The skin also has a thick outer layer (the epidermis) that acts as a barrier against pathogens and environmental damage. Additionally, sweat glands help in thermoregulation by facilitating evaporative cooling, while sensory receptors within the skin enable the detection of environmental stimuli. These adaptations collectively enhance the skin's protective functions and overall homeostasis.
