Why must a salamander's skin always be moist?

A salamander's skin must always be moist because it plays a crucial role in their respiration and hydration. Salamanders absorb oxygen not just through their lungs, but also directly through their skin, a process known as cutaneous respiration. If their skin dries out, it can hinder this oxygen absorption, making them vulnerable to suffocation. Additionally, moisture helps them regulate their body temperature and maintain a healthy balance of electrolytes, which is essential for their survival in their often-damp habitats. In the wild, these quirky little critters often inhabit moist environments like forests, marshes, and caves. They rely on the humidity to survive and are often found hiding under logs or leaves that retain moisture. For pet owners or budding herpetologists, ensuring a humid habitat is key to keeping these slimy friends healthy and happy. So, if you're ever around a salamander, remember, they might prefer the vibe of a steamy spa day over the dry desert sun!
