Polar Bears

Polar bears have been known

to swim up to 100 miles at

one time.

ANIMALS Polar bears are mammals. They also live around water. What

other animals shown in the table are mammals that live around water?

One way to show this relationship is with a Venn diagram. A Venn

diagram is an arrangement of overlapping circles used to show how two

or more sets of data are related. In a Venn diagram, each set of data is

shown separately and the items that belong to both sets are represented

by the overlapping section.
