S.N	Warm Blooded Animals	S.N	Cold Blooded Animals
1.	Warm-blooded animals maintains their thermal homeostasis and keep their body temperature consistent irrespective of the external temperature.	1.	Cold-blooded animals have fluctuating body temperature which follows the external temperature and fails to maintain thermal homeostasis.
2.	They require more amount of energy to regulate their body temperature and so their need of food is higher.	2.	They require less energy to maintain their body temperature, hence they need less amount of food.
3.	The temperature of the body is independent of the outer environment.	3.	The temperature of a body depends on the temperature of the outer environment.
4.	They are easily adaptable to any environment and temperatures.	4.	They cannot survive in any of the extreme temperature, especially cold.
5.	Mammals and fish.	5.	Fish, reptiles, amphibians, invertebrates.
