Fiercely protective of his pride, or family unit, male lions patrol a vast territory normally covering about 100 square miles (260 square kilometers).
African Lion Profile
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.
Only male lions boast manes, the impressive fringe of long hair that encircles their heads. Males defend the pride's territory, which may include some 100 square miles (259 square kilometers) of grasslands, scrub, or open woodlands. These intimidating animals mark the area with urine, roar menacingly to warn intruders, and chase off animals that encroach on their turf.
Female lions are the pride's primary hunters. They often work together to prey upon antelopes, zebras, wildebeest, and other large animals of the open grasslands. Many of these animals are faster than lions, so teamwork pays off.
After the hunt, the group effort often degenerates to squabbling over the sharing of the kill, with cubs at the bottom of the pecking order. Young lions do not help to hunt until they are about a year old. Lions will hunt alone if the opportunity presents itself, and they also steal kills from hyenas or wild dogs.
Lions have been celebrated throughout history for their courage and strength. They once roamed most of Africa and parts of Asia and Europe. Today they are found only in parts of sub-Saharan Africa, except for one very small population of Asian lions that survives in India's Gir Forest.
Asian Lion
Only 200 or so Asian lions exist in the wild. A former royal reserve, India's Gir Forest, is the last home of this lion subspecies.
Asian Lion Profile
Nearly all wild lions live in sub-Saharan Africa, but one small population of Asian lions exists in India's Gir Forest. Asian lions and African lions are subspecies of the same species.
Asian lions once prowled from the Middle East to India. Now, only 200 to 260 of these magnificent animals survive in the wild. The Gir Forest's dry teak woods were once a royal hunting ground. Today they are a reserve where the endangered Asian lions are heavily protected. An additional 200 Asian lions live in zoos.

Siberian Tiger
Many conservation programs have been established to save the critically endangered Siberian tiger, whose numbers have dwindled to mere hundreds in the wild.
Siberian Tiger Profile
Siberian (or Amur) tigers are the world's largest cats. They live primarily in eastern Russia's birch forests, though some exist in China and North Korea. There are an estimated 400 to 500 Siberian tigers living in the wild, and recent studies suggest that these numbers are stable. Though their northern climate is far harsher than those of other tigers, these animals have some advantages. Northern forests offer the lowest human density of any tiger habitat, and the most complete ecosystem. The vast woodlands also allow tigers far more room to roam, as Russia's timber industry is currently less extensive than that of many other countries.
Tigers are the largest of all wild cats and are renowned for their power and strength. There were once eight tiger subspecies, but three became extinct during the 20th century. Over the last 100 years, hunting and forest destruction have reduced overall tiger populations from hundreds of thousands to perhaps 5,000 to 7,000. Tigers are hunted as trophies and also for body parts that are used in traditional Chinese medicine. All five remaining tiger subspecies are endangered, and many protection programs are in place. Poaching is a reduced—but still very significant—threat to Siberian tigers.
Tigers live alone and aggressively scent-mark large territories to keep their rivals away. They are powerful hunters that travel many miles to find prey, such as elk and wild boar, on nocturnal hunts. Tigers use their distinctive coats as camouflage (no two have exactly the same stripes) and hunt by stealth. They lie in wait and creep close enough to attack their victims with a quick spring and a fatal pounce. A hungry tiger can eat as much as 60 pounds (27.2 kilograms) in one night, though they usually eat less.
Despite their fearsome reputation, most tigers avoid humans; however, a few do become dangerous maneaters. These animals are often sick and unable to hunt normally, or live in areas where their traditional prey has vanished.
Females give birth to litters of two to six cubs, which they raise with little or no help from the male. Cubs cannot hunt until they are 18 months old, and remain with their mothers for two to three years, when they disperse to find their own territory.

Born in captivity, these two Bengal tiger youngsters will never be fit for release into the wild. Tiger cubs, like all young animals, enjoy play-fighting.
