What does cold blooded mean?

Warm blooded creatures such as mammals have a body temperature which stays roughly the same whatever surroundings they are in. This temperature varies from creature to creature, for example the body temperature of any healthy human is 98.4 degrees Fahrenheit.

Some creatures are cold blooded, which means that the body temperature varies according to the animals surrounding. This means that animals which are cold blooded have to live in certain areas suitable for their survival. This is one reason why you never find cold blooded creatures living in very cold surrounding like polar regions they would die of cold because they would not be able to maintain a body temperature suitable for life. Fish are cold blooded, so are amphibians and reptiles.
