Final answer:

Amphibians have a moist, permeable skin crucial for cutaneous respiration, distinguishing them from reptiles.


Explanation:

Amphibians differ from reptiles in various ways, one significant characteristic being their moist, permeable skin that allows for cutaneous respiration. This feature enables them to exchange oxygen and carbon dioxide with the environment through their skin. In contrast, reptiles typically have scales that serve as a protective barrier and do not facilitate gas exchange.
