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 other is Grevy''s zebra, named for Jules Grevy, a president of France in the 1880s who received one from Abyssinia as a gift, and now found mostly in northern Kenya. (The third species, Equus zebra, is the mountain zebra, found in southern and southwestern Africa.) The long-legged Grevy''s zebra, the biggest of the wild equids, is taller and heavier than the Burchell''s, with a massive head and large ears. Zebras have shiny coats that dissipate over 70 percent of incoming heat, and some scientists believe the stripes help the animals withstand intense solar radiation. The black and white stripes are a form of camouflage called disruptive coloration that breaks up the outline of the body. Although the pattern is visible during daytime, at dawn or in the evening when their predators are most active, zebras look indistinct and may confuse some predators by distorting the true distance between them and their prey.

The larger Baringo or Rothschild''s giraffe (G.c. rothschildi) of western Kenya and eastern Uganda has chestnut patches separated by broader white lines but no spotting below the knees. This species can have up to five horns instead of the usual two or three. The Masai giraffe (G.c. tippelskirchi) of Tanzania and southern Kenya has irregular star-shaped brown or tan spots. Giraffes are found in arid and dry-savanna zones south of the Sahara, wherever trees occur. Although a relatively quiet animal, the giraffe is not mute. Giraffes bellow, grunt, bray in distress, moan and emit short flutelike notes. They have acute senses of hearing and sight, often alerting other animals to nearby predators. Giraffes use a home range but are not territorial. The males are hierarchical and sometimes spar by standing side by side and lowering and swing their heads at one another. The blows can be so strong that their necks entwine.
