Detailed explanation-1: -Like amphibians, reptiles are ectotherms with a slow metabolic rate. Their metabolism doesn’t generate enough energy to keep their body temperature stable. Instead, reptiles regulate their body temperature through their behavior.
Detailed explanation-2: -Because of their slow metabolism and heat-seeking behavior, reptiles are cold-blooded. Reptile reproduction also depends on temperature.
Detailed explanation-3: -Being cold blooded requires far less fuel to function. A crocodile needs a fraction of the food a lion of the same weight needs, and can live half a year without eating. Due to their slow metabolism, reptiles can do well in areas where food sources are too low for most mammals and birds to live.
Detailed explanation-4: -reptiles and amphibians breathe only through their lungs and they have dry, scaly skin that prevents them from drying out.
Detailed explanation-5: -Reptilian lungs are considerably more complex than those of amphibians, showing much more internal partitioning to provide additional surface area for gas exchange between lung gas and blood. The most complex reptilian lungs are found in sea turtles such as Chelonia mydas, the green turtle.
