Grévy's zebra
The Grévy's zebra is the largest of all wild equines. It is from head to tail with a tail, and stands high at the withers. These zebras weigh . Grévy's zebra differs from the other two zebras in its more primitive characteristics. It is particularly mule-like in appearance; the head is large, long, and narrow with elongated nostril openings; the ears are very large, rounded, and conical and the neck is short but thick. The zebra's muzzle is ash-grey to black in colour with the lips having whiskers. The mane is tall and erect; juveniles have a mane that extends to the length of the back and shortens as they reach adulthood.
Zebra (chess)
As a component of other pieces, it has about the same value as a knight (both pieces can move to eight squares), but its long move carries the danger of causing unstoppable attacks in the opening and winning large amounts of material. Ralph Betza opined that the zebra's move was too large to be functional on an 8×8 board, and that only on a 10×10 board or larger would it be worth its ideal value of about a knight.
