INTRODUCTION

MEET THE GRIZZLY BEAR

A grizzly bear stands in a roaring stream and plunges its
head into the water. The bear comes up with a large silver
fish in its mouth. Grizzly bears belong to a group of animals
called mammals. Other groups of animals include insects, fish,
amphibians, reptiles, and birds.

This grizzly bear has caught a fish! Grizzly bears eat both plants and animals.

What are mammals? Mammals
are warm- blooded animals.
This means they keep their
bodies at a steady temperature.
All mammals are vertebrates,
or animals with backbones.
All mammals have fur or
hair. And all mammal
mothers feed their babies
milk. Grizzly bears share
these traits with other
mammals. But grizzly
bears also have some
traits that set them apart.

CHAPTER

WHAT DO GRIZZLY BEARS
LOOK LIKE?

Grizzly bears are a member of the bear family. This family of
mammals includes polar bears and giant pandas. A grizzly bear
measures to feet (0.9 to 1.2 meters) at the shoulder and up
to feet (2.4 m) standing up. It weighs up to pounds (363
kilograms). Male grizzly bears are almost twice as large as females.

The head of a grizzly bear is large and round. A grizzly bear has
sharp teeth, round ears, and a muscular hump at its shoulders. It
also has long claws on its front feet. The claws and the shoulder
muscles make the grizzly a powerful digger.

DID YOU KNOW?

Grizzly bears are
BROWN BEARS
that live only in North
America. Other brown
bears live in Europe
and Asia.

A grizzly bear is a kind of bear called a brown bear. Even so,
a grizzlys fur may be blond, brown, or black. The thick fur
covers the grizzly bears head and body. Grizzly fur is often
white- tipped, or grizzled, which is how the bear got its name.

GRIZZLY BEARS VS.
WOLVERINES

Wolverines climb through snow- covered mountains and
forests across northern Europe, Asia, and North America.
Wolverines are the largest member of the weasel family.
Although wolverines are much smaller than grizzly bears,
the two animals look a lot alike. The Blackfoot American
Indian term for wolverine even translates to skunk bear.

Both grizzly bears and wolverines have rounded ears and
pointy teeth. Wolverines can crush bone and chew through
frozen meat with their powerful jaws. And like grizzly
bears, wolverines have sharp claws. These claws help the
wolverine dig and climb.

Some wolverines have pale stripes in their fur.
