Lions may hunt at any hour, but they typically go after large prey at night. They hunt together to increase their success rate, since prey can be difficult to catch and can outrun a single lion. The lions fan out along a broad front or semicircle to creep up on prey. Once with within striking distance, they bound in among the startled animals, knock one down and kill it with a bite to the neck or throat. Hunts are successful about half the time. Cooperative hunting enables lions to take prey as large as wildebeests, zebras, buffaloes, young elephants, rhinos, hippos and giraffes, any of which can provide several meals for the pride. Mice, lizards, tortoises, warthogs, antelopes riding and even crocodiles also form part of a lion''s diet. Because they often take over kills made by hyenas, cheetahs and leopards, scavenged food provides more than 50 percent of their diets in areas like the Serengeti plains.

Litters consist of two or three cubs that weigh about 3 pounds each. Some mothers carefully nurture the young; others may neglect or abandon them, especially when food is scarce. Usually two or more females in a pride give birth about the same time. A lioness will permit cubs other than her own to suckle, sometimes enabling a neglected infant to survive. Capable hunters by 2 years of age, lions become fully grown between 5 and 6 years and normally live about 13 years. Lions have long been killed in rituals of bravery, as hunting trophies and for their medicinal and magical powers. Although lions are now protected in many parts of Africa, they were once considered to be stock-raiding vermin and were killed on sight. In some areas, livestock predation remains a severe problem. Early written records described the giraffe as "magnificent in appearance, bizarre in form, unique in gait, colossal in height and inoffensive in character."

The lion is a magnificent animal that appears as a symbol of power, courage and nobility on family crests, coats of arms and national flags in many civilizations. Lions at one time were found from Greece through the Middle East to northern India, but today only a very small population remains in India. In the past lions lived in most parts of Africa, but are now confined to the sub-Saharan region. Most cat species live a fundamentally solitary existence, instructions but the lion is an exception. It has developed a social system based on teamwork and a division of riding labor within the pride, and an extended but closed family unit centered on a group of related females. The average pride consists of about 15 individuals, including five to 10 females with their young and two or three territorial males that are usually brothers or pride mates of the lion king.
