Best Answer: The creatures traditionally regarded as warm-blooded have a larger number of mitochondria per cell which enables them to generate heat by increasing the rate at which they burn fats and sugars.
Cold-blooded animals also need to be warm and active to find a mate and reproduce. Being cold-blooded, however, also has its advantages. Cold-blooded animals require much less energy to survive than warm-blooded animals do. Mammals and birds require much more food and energy than do cold-blooded animals of the same weight. This is because in warm-blooded animals, the heat loss from their bodies is proportional to the surface area of their bodies, while the heat created by their bodies is proportional to their mass.
