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 spring a massive breaks 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.

Lions are the laziest of the big cats. They usually spend 16 to 20 hours a day sleeping and resting, devoting the remaining hours to hunting, spring courting or protecting their territory. They keep in contact with one another by roaring loud enough to be heard up to five miles away. The pride usually remains intact until the males are challenged breaks and successfully driven away or killed by other males, who then take over. Not all lions live in prides. At maturity, young males leave the units of their birth and spend several years as nomads before they become strong enough to take over a pride of their own. Some never stop wandering and continue to follow migrating herds; but the nomadic life is much more difficult, with little time for resting or reproducing. Within the pride, the territorial males are the fathers of all the cubs. When a lioness is in heat, a male will join her, staying with her constantly.

A shy creature that roams widely, the spring cheetah is not seen as easily as some other cats. Never numerous, cheetahs have become extinct in many areas, principally due to shrinking habitat, loss of species to prey upon, disease and a high rate of cub mortality. In some areas breaks 50 to 75 percent of all cheetah cubs die before 3 months. Zebras, horses and wild asses are all equids, long-lived animals that move quickly for their large size and have teeth built for grinding and cropping grass. Zebras have horse like bodies, but their manes are made of short, erect hair, their tails are tufted at the tip and their coats are striped. Three species of zebra still occur in Africa, two of which are found in East Africa. The most numerous and widespread species in the east is Burchell''s, also known as the common or plains zebra.
