Vertebrates are classified into two major classes: warm-blooded and cold-blooded. Warm-blooded organisms are those that maintain a constant body temperature, irrespective of the temperature of their surroundings. This means that when their surroundings are cold, these organisms must convert food to energy that can be used to increase their body temperature. During hot weather, warm-blooded organisms must use mechanisms such as sweating to lower their internal temperature. Warm-blooded organisms include humans, dogs, cats, and tigers.

Cold-blooded animals, on the other hand, are incapable of maintaining their body temperature and hence must take the temperature of their surroundings. Thus, these organisms are cold in colder weather and warm in hot weather. This also means that they will be very active in warm climates and very sluggish in colder climate. Some examples of cold-blooded animals include lizards, fish, snakes, and naked mole rats.
