Detailed explanation-1: -Almost all reptiles are cold-blooded, and most lay eggs-though some, like the boa constrictor, give birth to live young. Instead of possessing gills like fish or amphibians, reptiles have lungs for breathing.
Detailed explanation-2: -Reptiles are mostly terrestrial and have a creeping or crawling mode of locomotion. All reptiles have a three chambered heart except the crocodiles, alligators which have a four chambered heart. Reptiles have a body that is covered by dry cornified skin, epidermal scales or scutes.
Detailed explanation-3: -Animals that cannot generate internal heat are known as poikilotherms (poy-KIL-ah-therms), or cold-blooded animals. Insects, worms, fish, amphibians, and reptiles fall into this category-all creatures except mammals and birds.
Detailed explanation-4: -Animals that cannot naturally regulate their body temperatures are considered to be ectothermic or cold-blooded. These animals use sources of heat outside of their own bodies to maintain their metabolic functions. Insects, arachnids, fish, reptiles, and amphibians are generally cold-blooded. Lizard is a reptile.
