Cold-blooded animals means the animals don't generally use their own energy to warm themselves. Warm-blooded animals heat themselves with energy from food, which makes them more hungry and makes them eat more. The only two warm-blooded groups are mammals and birds. Other animals such as reptiles, fish, and invertebrates, are cold-blooded.
