Mammals (class Mammalia)
Mammals are vertebrates of the taxonomic class Mammalia including animals such as American marsupials (order Didelphimorphia), Insectivores (order Soricomorpha), Bats (order Chiroptera), Edentates (order Cingulata), Lagomorphs (order Lagomorpha), Rodents (order Rodentia), Carnivores (order Carnivora), and Artiodactyls (order Artiodactyla). Thought of as warm-blooded, mammals are endotherms, meaning they are able to regulate their own body temperature independently of the temperature of their surroundings. Mammal characteristics include skin covered with hairs, females with mammary glands that secrete milk to feed young, and a reproduction strategy of internal fertilization and bearing relatively mature live offspring. In Alabama, Kentucky, Mississippi, and Tennessee, mammals are represented by numerous taxonomic families within the taxonomic orders below:
