Amphibians are devoid of scales because they are descendants of fish, which also lack scales. Early amphibians evolved from lobe-finned fish, which had bony plates in their skin instead of scales. Over time, these bony plates transformed into the smooth, moist skin characteristic of modern amphibians. This adaptation allowed for better gas exchange through the skin, crucial for their semi-aquatic lifestyle.
Amphibians are cold-blooded animals that have a backbone, lungs, and permeable skin. They have flat skulls that are also wide, movable eyelids,Êand limbs. Frogs toads and salamanders are amphibians belonging to different orders.
