Suppose you saw a wolf in the woods. Would you be scared? Many scary stories have been told about these strong meat-eating animals. Wolves like to gather in groups and howl at night. In lonely places, this howling sounds frightening. But wolves almost never attack people.
WOLF OR DOG?
From a distance you might not be able to tell a wolf from a dog. Wolves look very much like some dogs, such as German shepherds.The main difference is size. Wolves are bigger. They can be 6 feet (2 meters) long and weigh 200 pounds (90 kilograms).
If you saw a horse with black-and-white stripes, you might think you were “seeing things.” But you would be seeing a zebra. Zebras are a kind of horse. They walk, trot, canter, and gallop just as horses do. Zebras live only in Africa.
There are three species (kinds) of zebras: Grévy’s zebra, the mountain zebra, and the plains zebra (also known as Burchell’s zebra). Each kind of zebra has its own pattern of stripes. And you can tell individual zebras apart. No two zebras have exactly the same stripes.
WHY DO ZEBRAS HAVE STRIPES?
Some scientists think zebra stripes act as protection. Zebras like to hang out together in groups.
You don’t have to go to Africa to see an elephant. You don’t have to go to the North Pole to see a polar bear. You can see elephants, bears, lions, crocodiles, hawks, and all kinds of other wild animals at a zoo.
Zoos are places where animals are kept so that you can learn about them. Zoos are also places where scientists study animals. Some zoos help preserve endangered animals.
WHAT DOES A ZOO LOOK LIKE?
Zoos once kept animals in cages. Today, they try to keep animals in larger, open places. The places look like the home of each animal that lives there.
