Answer:

BACKGROUND

Classifying animals into categories and groups

based on their similarities and differences is the

first step in studying and understanding their

origins, development and interdependence.

Mammals have the following characteristics:

1. They are covered with hair or fur.

2. They are warm-blooded (mean-

ing their internal body temperature

is maintained at a constant level

regardless of external conditions).

3. They are usually born alive and relatively well-devel-

oped, having grown inside the mother’s body in a special

organ called a uterus. The time spent developing in the

uterus before birth is called the gestation period and

varies in length from species to species (from about

13 days in the Virginia opossum to 210 days in the

white-tailed deer).

4. After birth the young are fed with milk that is pro-

duced by mammary glands.

5. They have larger and more complex brains than

any other group of animals.

Focusing on these five characteristics will enhance the students’ awareness of

and interest in mammals of Illinois. It will also provide a frame of reference for

exploring the similarities and differences among members of the animal kingdom

and how those characteristics relate to the environment and lifestyle of individual

species.
