Zebras are known for their mostly vertical black and white striped coat. Their patterns of stripes are as individual as a human fingerprint. This species is closely related to the horse and the donkey. These unique animals usually live in small family groups of four to nine animals, and a single stallion leads them. When males are not leading a family group, then they form bachelor groups until they can establish their own herd. Zebras are widespread throughout Africa.
