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, but the lion is an exception. It has developed a social system based on teamwork and a division of 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. The divingwatches 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, divingwatches 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 divingwatches 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, 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 divingwatches males are challenged 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.
