The stripes on Grevy''s zebras are more numerous and narrow than those of the plains zebra and do not extend to the belly. In all zebra species, the stripes on the forequarters form a triangular pattern; Grevy''s have a similar pattern on the hindquarters, while others have a slanted or horizontal pattern. Burchell''s zebras inhabit savannas, from treeless grasslands to open woodlands; they sometimes occur in tens of thousands in migratory herds on the Serengeti plains. Grevy''s zebras are now mainly restricted to parts of northern Kenya. Although they are adapted to semi-arid conditions and require less water than other zebra species, these zebras compete with domestic livestock for water and have suffered heavy poaching for their meat and skins. Family groups are stable members maintaining strong bonds over many years. Mutual grooming, where zebras stand together and nibble the hair on each other''s neck and back, helps develop and preserve these bonds.

When a foal is born the mother keeps all other zebras (even the members of her family) away from it for 2 or 3 days, until it learns to recognize her by sight, voice and smell. While all foals have a close association with their mothers, the male foals are also close to their fathers. They leave their group on their own accord between the ages of 1 and 4 years to join an all-male bachelor group until they are strong enough to head a family. Zebras are important prey for lions and hyenas, and to a lesser extent for hunting dogs, leopards and cheetahs. When a family group is attacked, the members form a semicircle, face the predator and watch it, ready to bite or strike should the attack continue. If one of the family is injured the rest will often encircle it to protect it from further attack.

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.
