No animal has a more distinctive coat than the zebra. Each animal's stripes are as unique as fingerprints—no two are exactly alike—although each of the three species has its own general pattern.
Why do zebras have stripes at all? Scientists aren't sure, but many theories center on their utility as some form of camouflage. The patterns may make it difficult for predators to identify a single animal from a running herd and distort distance at dawn and dusk. Or they may dissuade insects that recognize only large areas of single-colored fur or act as a kind of natural sunscreen. Because of their uniqueness, stripes may also help zebras recognize one another.
Population and Herd Behavior
Zebras are social animals that spend time in herds. They graze together, primarily on grass, and even groom one another.
Plains (Burchell's) zebras are the most common species. They live in small family groups consisting of a male (stallion), several females, and their young. These units may combine with others to form awe-inspiring herds thousands of head strong, but family members will remain close within the herd.
Zebras must be constantly wary of lions and hyenas. A herd has many eyes alert to danger. If an animal is attacked, its family will come to its defense, circling the wounded zebra and attempting to drive off predators.
The loss of animal species is irreversible and potentially catastrophic, not to mention heartrendingly sad. Where do we stand? Face the facts with this quiz.
The Hawaiian monk seal is one of the oldest species of seal on the planet. But their tenure in paradise is perilously close to its end; only about 1,100 seals remain in the wild.
They’re rarely seen. Even less often photographed. Bryde’s whales rocket through Pacific shallows to gorge on fish. Dive in for more.
