2. OVERVIEW
For all of their roaring, growling, and ferociousness, lions are family animals and truly social in their own communities. They usually live in groups of 15 or more animals called prides. Prides can be as small as 3 or as big as 40 animals. In a pride, lions hunt prey, raise cubs, and defend their territory together. In prides the females do most of the hunting and cub rearing. Usually all the lionesses in the pride are related—mothers, daughters, grandmothers, and sisters. Many of the females in the pride give birth at about the same time. A cub may nurse from other females as well as its mother. Each pride generally will have no more than two adult males.

3. While the females usually live with the pride for life, the males often stay for only two to four years. After that they go off on their own or are evicted by other males who take over the pride. When a new male becomes part of the pride it is not unusual for him to kill all the cubs, ensuring that all future cubs will have his genes. The main job of males in the pride is defending the pride's territory. A male's loud roar, usually heard after sunset, can carry for as far as five miles (eight kilometers). The roar warns off intruders and helps round up stray members of the pride.

4. Hunting generally is done in the dark by the lionesses
Hunting generally is done in the dark by the lionesses. They often hunt in groups of two or three, using teamwork to stalk, surround, and kill their prey. Lionesses aren't the most successful of hunters, because they usually score only one kill out of several tries. After the kill the males usually eat first, lionesses next—and the cubs get what's left. Males and females fiercely defend against any outside lions that attempt to join their pride.

5. Because of their size, strength, and predatory skills, lions are considered one of the “big cats.” Tigers, cheetahs, leopards, jaguars, and cougars are also part of this grouping.

6. GRAY WOLF

7. OVERVIEW
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. Wolves communicate with more than howls! They whimper and whine, growl and bark, yelp and snarl. They also use scents produced by their bodies to communicate. One source of scent is urine, which they use to mark territory and to tell other wolves in their own pack where they are. Another way wolves communicate is through body language. If a wolf feels confident, it will approach another wolf with its head and tail held high and ears perked up. If you saw a wolf slinking toward another with its body lowered, its tail between its legs, and its ears flattened, you'd know it was approaching a dominant animal. 

8. When a wolf wants to play, it prances about happily and bows—lowering the front of its body while its rump stays up in the air with its tail wagging. A wolf's body language may remind you of another animal: a pet dog. Wolves and dogs are closely related, and the ways they communicate are similar.  Young wolves stay in their parents' pack for at least two or three years before some of them take off to join other packs or to start their own. Wolf pups play a lot as they're growing. They leap and pounce, chase and wrestle, play hide-and-seek and tag—a lot like you do!  In some areas, gray wolfs are classified as endangered, but in most places they are classified as having healthy populati

9. BLACK RHINOCEROS

10. OVERVIEW
Black rhinoceroses have a sort of attack-first-and-ask-questions-later attitude. When a rhino catches the scent of a human or anything else unfamiliar, it is likely to charge. Rhinos can't see well, so they sometimes charge objects like trees and rocks, mistaking them as threats. But rhinos have keen senses of smell and hearing. Rhinos sometimes fight with each other. Black rhinos use the bigger of the two horns on their noses as weapons in a fight. Their horns, made of a substance similar to that of human fingernails, sometimes break off, but they regenerate, or grow back. Female rhinos also use their horns to protect their babies from predators such as lions, crocodiles, and hyenas.

11. In spite of their fierce reputation, black rhinos do have a softer side. The females are very attentive mothers. They look after their young for years, protecting them from enemies and teaching them how to survive independently. Young rhinos usually stay with their mothers until a sibling is born. By then they're generally over two years old, almost adult size, and ready to live on their own. Humans are the only real threat to adult black rhinos. In several Asian cultures, people believe that a rhino horn provides powerful medicine for a variety of ailments. Other people, who live mainly in northern Africa, use rhino horns to make the handles for special daggers. Since rhino horns fetch high prices, many poachers are willing to break the law and kill these endangered animals. There are five different species of rhinoceros: black, white, Javan, great Indian, and Sumatran.

12. GIANT PANDA

13. OVERVIEW
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. Occasionally they eat other vegetation, fish, or small animals, but bamboo accounts for 99 percent of their diets. Pandas eat fast, they eat a lot, and they spend about 12 hours a day doing it. The reason: They digest only about a fifth of what they eat. Overall, bamboo is not very nutritious. To stay healthy, they have to eat a lot—up to 15 percent of their body weight in 12 hours—so they eat fast. 

14. Pandas' molars are very broad and flat
Pandas' molars are very broad and flat. The shape of these teeth helps the animals crush the bamboo shoots, leaves, and stems they eat. To get the bamboo to their mouths, they hold the stems with their front paws, which have enlarged wrist bones that act as thumbs for gripping. A panda should have at least two bamboo species where it lives, or it will starve.  Pandas are shy; they don't venture into areas where people live. This restricts pandas to very limited areas.
