According to the seven characteristics of life, all living beings must be able to respond to stimuli; grow over time; produce offspring; maintain a stable body temperature; metabolize energy; consist of one or more cells; and adapt to their environment. However, some life-forms don't fit every single characteristic.

Although animal cells can vary considerably depending on their purpose, there are some general characteristics that are common to all cells. These include structures such as the plasma membrane, cytoplasm, nucleus, mitochondria, and ribosomes.

Adaptations are any behavioral or physical characteristics of an animal that help it to survive in its environment. These characteristics fall into three main categories: body parts, body coverings, and behaviors. Any or all of these types of adaptations play a critical role in the survival of an animal.

Types of Body Coverings One of the main characteristics that is used to distinguish one class of animals from another is type of skin covering. Mammals have hair or fur, birds have feathers, reptiles have dry scales, amphibians have soft, moist skin, and fish have wet, slimy scales.

The main difference between mammals and other vertebrates are three characteristics: hair, milk production in mammary glands, and three bones in the inner ear. Extant mammals are divided into three subclasses based on reproductive techniques (monotremes, marsupials, and placentals) consisting of 27 orders.
