Armadillos are mammals, thus making them warm blooded creatures. Warm blooded creatures such as the armadillo maintain their own body temperatures internally and these temperatures do not vary depending on their external environment. Armadillos live primarily in warm habits, including areas such as Texas, Florida, Central, and South America. However, it should be noted that this selection in habitat has more to do with their body cover than the fact that they are warm blooded creatures.
Mammals can be defined as having hair. They differ in this way from reptiles, since reptiles possess scales. At first glance, it is often difficult to notice the hair of some species of armadillos, but they do in fact have hair though it is very sparse. This is especially true for their sides and underbelly. These creatures use this hair as a way to protect themselves from the cold temperature as well as dust or other environmental conditions that may come across their way. Since these animals are warm blooded however, and tend to reside in warmer areas, this could be a reason for their hair being so sparse.
Another way one can tell that armadillos are warm blooded mammals is because with very few exceptions, mammals (warm blooded creatures) give live birth to babies that drink milk that comes from their mother’s mammary glands. Whereas, cold blooded creatures such as reptiles usually lay eggs or give live birth but do not nurse them. Mammals such as the armadillo can make their own heat when they are outside and start to get cold.
