Mammals - Class Mammalia
Mammals (Class Mammalia) are characterized by mammary glands, hair, a diaphram, a four-chambered heart, and a large cereberal cortex. 70 million years ago when reptile diversity declined, mammals took over habitats once unavailable to them.

An Introduction to Mammals
To understand mammals, it first helps to understand how they fit into the classification system of all animals. Mammals, as a group of animals, belong to the Class Mammalia. The Class Mammalia, in turn, belongs to the larger group known as the vertebrates (animals with backbones; also called the Phylum Chordata).

Mammal Research and Conservation
Mammal research and conservation is a vast subject. Studies and protection efforts are often aimed at a single species or a small number of species. In the topics that follow, you will find information about various areas of mammal study such as primatology, marine mammal research, carnivore research and many others.

Nine Characteristics of Mammals
