ANIMALS

lions

Lions are the only cats that live in groups, which are called prides. Prides are family units that may include up to three males, a dozen or so females, and their young. All of a pride's lionesses are related, and female cubs typically stay with the group as they age. Young males eventually leave and establish their own prides by taking over a group headed by another male

Cheetah

The cheetah is the world's fastest land mammal. With acceleration that would leave most automobiles in the dust, a cheetah can go from 0 to 60 miles (96 kilometers) an hour in only three seconds. These big cats are quite nimble at high speed and can make quick and sudden turns in pursuit of prey.

tigers

Easily recognized by its coat of reddish-orange with dark stripes, the tiger is the largest wild cat in the world. The big cat weighs up to 720 pounds (363 kilograms), stretches 6 feet (2 meters) long, and has a 3-foot- (1-meter-) long tail. The powerful predator generally hunts alone, able to bring down prey such as deer and antelope.

dolphins

Their moans, groans, squeaks, whistles, and grunts can sound as if they're a heavy metal band. But bottlenose dolphins make their own kind of music. Many of the sounds they make could be imitated by holding a balloon tightly by the neck, then letting the air out faster and slower.

Brown bear

As winter approaches, brown bears—often called grizzly bears—prepare for a long hibernation. During the fall, a brown bear eats practically around the clock, stocking up for the four to seven months when it'll have to live off stored body fat. A grizzly may chow down on 90 pounds (40 kilograms) of food each day.

Coyotes

Coyotes in Los Angeles and Dallas? It's hard to imagine, but it's true. While populations of many other animals are shrinking, coyote populations are actually increasing. Coyotes once lived only in prairies and deserts of the western United States and in Mexico. Today they thrive almost anywhere in North America.

giants pandas

High in dense bamboo forests in the misty, rainy mountains of southwestern China lives one of the world's rarest mammals: the giant panda, also called the panda. Only about 1,000 of these black-and-white relatives of bears survive in the wild. Pandas eat almost nothing but bamboo shoots and leaves.

Wolves

The howl of a gray wolf isn't only a mysterious sound in the wilderness. Howling sends other wolves a message. It might mean "I'm here, where are you?" or "Stay away from my territory." Wolves live in groups called packs. The wolves' communication skills are very important to the pack's survival. Wolves work together to hunt, raise their young, and protect their territory.

Jaguar

Jaguars are the largest of South America's big cats and the third largest cats in the world. At one time jaguars roamed all the way to the U.S.-Mexico border, but jaguars are now only occasionally sighted in Texas and Arizona. Most jaguars are found in the Amazon River basin.

Gorillas

Youngsters tumble, climb, and run playing follow the leader. Another group plays a rowdy game of king of the mountain. Several adults watch the action, relaxing nearby. Is this a playground scene at school? No, guess again. It's a lush mountain forest high in the Virunga mountains of Africa, and the playmates are young mountain gorillas under the watchful eyes of their mothers.

Zebra

There is no mistaking what you're seeing when you spot a horselike animal with black-and-white stripes: it's a zebra. And each zebra has its own unique pattern of those distinctive stripes, just as humans have their own unique pattern of fingerprints.

Vampires bats

While much of the world sleeps, vampire bats emerge from dark caves, mines, tree hollows, and abandoned buildings in Mexico and Central and South America. They glide stealthily through the night air as they search for food. Like the legendary monster from which they get their name, these small mammals drink the blood of other animals for survival.

Tarantulas

Tarantulas give people the creeps because they have large, hairy bodies and legs. Even the bad guy in the movie Home Alone lets out a blood-curdling scream when Macauley Culkin places his brother's pet tarantula on his face! While these large spiders can take a painful bite out of a human, a tarantula's venom is weaker than from a typical bee sting.

Elephants

When you think elephant, you probably think trunk. An adult African elephant's trunk is about seven feet (two meters) long! It's actually an elongated nose and upper lip. Like most noses, trunks are for smelling. But they're also for touching and grasping.
