The stripe pattern of a Grevy's zebra is as distinctive as human fingerprints. It is also the most important adaptation for its survival, as movements of stripes within the herd are very confusing to a predator
The Grevy is the largest of the wild equids, with the males five feet tall at the shoulders and weighing as much as 900 pounds with a thick, erect mane and short, tufted hair at the tip of the tail. The underbelly is white.
When a foal is born, the mother will walk around her newborn so it will see only her stripe pattern. This allows imprinting to occur, which is extremely important for survival. If a foal loses its mother, no other female will adopt it. Foals will nurse for six months and will remain with their mothers for two to three years. The Grevy's life span is about 18 years.
