Reptiles do not maintain their own body temperature within a narrow range like mammals and birds, so controlling their environmental temperature is critical for normal activity and good health. Reptiles are poikilothermic-which means that their body temperature alters with the surrounding environmental temperature.
1 Amphibians spend at least part of their lives in water and on land. 2  Amphibians do not have scales and their skin is permeable (molecules and gases can pass through). 3  Amphibians have gills for at least part of their lives. 4  Some species have gills only as larvae, while others can have gills throughout their lives.
