Mammals and adaptations – basic principles
How it works
Mammals are vertebrates. Typical for this group of animals is: The females produce milk and feed their young with it. Mammals have hair, at least in one phase of life. Most species give birth to live young; exceptions such as the platypus and the echidna lay eggs. Mammals are warm-blooded. Many species have developed adaptations to their habitat, for example fins in whales, webbed feet in beavers, thick fur in cold regions, or large ears to release heat in hot regions. These adaptations help them survive in habitats such as water, desert or forest.
Mammals are recognized as a group of animals by features such as hair in one phase of life, the feeding of the young by the females, and a warm-blooded body temperature. Adaptations to habitats are shown in body structure and behavior.
